Q S I 5 0 0 S E R I E S U S E R 1 Section G U I D E Getting Started Thank you for your purchase of a QSI 500 Series Camera. The QSI 500 Series family of thermoelectrically cooled CCD cameras is designed to produce scientific-grade images with wide dynamic range, excellent linearity and low noise. Your QSI 500 Series camera will provide years of service if properly treated and maintained.
Q S I 5 0 0 S E R I E S U S E R G U I D E What’s In the Box? Your QSI 500 Series camera was shipped in a water-tight Pelican case with custom-cut foam to provide the ultimate in protection. Please take a few minutes to examine your camera to make sure that it has arrived in good condition, and that the case contains the items listed below. Note that additional items purchased at the time of order may be included as well.
Q S I 5 0 0 S E R I E S U S E R G U I D E Get to Know Your Camera Take a few minutes to familiarize yourself with the external connections and features of your camera. The image above shows the major external features of a typical QSI 500 Series camera. The depth of the Camera Cover on your camera may differ depending on the internal options installed.
Q S I 5 0 0 S E R I E S U S E R G U I D E Install Software and Drivers The USB drivers and associated software included on the installation CD-ROM must be installed before connecting your QSI camera to your computer. Note: Do not connect your camera to your computer until instructed to do so during the camera installation process. Refer to the QSI 500 Series Camera Installation Guide for complete software and hardware installation instructions.
Q S I 5 0 0 S E R I E S U S E R G U I D E Connect the camera Select “Camera Control Window” from the View menu to open the Camera Control Window. MaxIm will open the Camera Control window and display the Setup tab. After MaxIm is installed it must be told which camera to use. Click the “Setup” button in the upper left corner under Main CCD Camera.
Q S I 5 0 0 S E R I E S U S E R G U I D E Select “QSI Universal” from the Camera Model list box. Click OK. That will take you back to the Camera Control Window. If you have a QSI camera with an internal color filter wheel you’ll also need to tell MaxIm about that by clicking “Setup” under “Filter Wheel” toward the upper right of the Setup tab. Select “QSI Universal” as the filter wheel model. Click OK.
Q S I 5 0 0 S E R I E S U S E R G U I D E Click the “Connect” button to establish communication between MaxIm and your QSI camera. If MaxIm fails to connect to the camera, double-check that power is supplied to the camera and that the USB cable is securely connected. Once MaxIm connects to the camera the Camera Control window will look like this: Note: This example assumes the camera does not have a color filter wheel.
Q S I 5 0 0 S E R I E S U S E R G U I D E View the image MaxIm will instruct the camera to acquire a bias frame and then automatically download and display the resulting image. Your screen should look something like this. Your display may vary somewhat from the screen shot above and the image displayed may be larger or smaller than that shown depending on your camera model.
Q S I 5 0 0 S E R I E S U S E R 2 Section G U I D E Camera Features and Operation Camera Attachment Options The camera can be attached to your telescope or lens in a variety of ways. The image above shows the industry standard T-Adapter with an attached 2" nosepiece. An optional 1.25" nosepiece is also available. The T-Adapter is compatible with a wide variety of standard accessories. An optional C-Adapter adapter is also available.
Q S I 5 0 0 S E R I E S U S E R G U I D E Using SLR Lenses The C-Adapter and T-adapter can be used to attach many standard SLR lens attached to your camera. The image at the right shows an Olympus OM series SLR lens attached to a QSI Model 520i camera. Optional SLR lens adapters are available to fit a variety of popular SLR camera lenses. See Section 6 in this Guide for a list of available adapters and compatibility requirements.
Q S I 5 0 0 S E R I E S U S E R G U I D E Electrical Connections The image at the left is a closeup of the bottom of the camera body. All electrical connections to the camera are made through the three connectors located on this connector panel. The panel is recessed into the camera body to protect the connectors when no cables are attached. DC Power Connector The camera is ordinarily powered by the included AC power adapter which plugs into the middle connector on the bottom of the camera.
Q S I 5 0 0 S E R I E S U S E R G U I D E Note: The camera power connecter uses a standard 2.1mm coaxial DC power connector with center positive. Inside diameter 2.1mm, outside diameter 5.5mm, length 10mm. Caution: Because of the wide range of potential power sources (especially with field operations that can also employ batteries, generators, DC inverters, etc.
Q S I 5 0 0 S E R I E S U S E R G U I D E Guider Control Port All QSI 500 Series cameras have a Guider Control Port that can be used in conjunction with MaxIm LE (or other CCD imaging software) to 'guide' your telescope mount for longduration astro-imaging. Ordinarily, the Port is only operational if the camera is being used as the 'Guider' camera, or if you’re using the QSI camera as your main imaging camera and have configured MaxIm to send guider correction signals through the main camera.
Q S I 5 0 0 S E R I E S U S E R G U I D E Cooling the Camera Cooling the CCD is essential for successful astro-imaging. Cooling dramatically reduces the dark current and resulting thermal noise in an image and makes long exposures practical. See the discussion in the 'CCD Imaging Overview' Section on dark current and noise. QSI 500 Series cameras use a very efficient thermo-electric cooler (TEC) which relies on the 'Peltier Effect' to cool the CCD.
Q S I 5 0 0 S E R I E S U S E R G U I D E will rise by only a few degrees after a full night of imaging. For additional details on the Liquid Heat Exchanger, see the Accessories section below. Note: The Fans can usually be turned off when using the LHX. In fact, the fans may actually decrease the cooling ability if the air is warmer than the liquid. Caution: It is generally advised that only water be used in the LHX.
Q S I 5 0 0 S E R I E S U S E R G U I D E that the surrounding environment. If the relative humidity is high enough, this action could drop the camera below the dew/frost point and condensation will form. Caution: Do not allow excessive dew or frost to collect in or on the camera. Exercise the normal precautions that you would with any precision optical or electronic device. Never use the LHX to drive the camera temperature so low that liquid water forms on or in the camera.
Q S I 5 0 0 S E R I E S U S E R G U I D E Note: Depending on the ambient temperature and Cooler setpoint, the time to reach the setpoint temperature can take as long as 15 minutes. Once the CCD temperature has stabilized at the setpoint value, it is recommended to allow the entire camera an additional 5 to 10 minutes to reach thermal equilibrium. Note: Best regulation is achieved when the power to the cooler is kept below 85%.
Q S I 5 0 0 S E R I E S U S E R G U I D E Internal Color Filter Wheel A five position filter wheel is available for some models of QSI 500 Series cameras. The filter wheel is designed to hold five standard 1.25" filters. Ordinarily, the filter wheel is supplied with an LRGB filter set as illustrated in the following image with filter positions 1-4 occupied by red, green, blue and luminance filters respectively. The filter wheel can be supplied without filters if desired.
Q S I 5 0 0 S E R I E S U S E R G U I D E Advanced Setup Options The QSI Configuration dialog box is used to view or change camera settings that are seldom modified. Bring up the Camera Control dialog box and click the Setup tab. The camera must be disconnected to proceed further. If necessary, click the Disconnect button. Click the Setup button in the upper left corner under “Main CCD Camera” to open the Setup QSI Universal dialog box for the Main camera.
Q S I 5 0 0 S E R I E S U S E R G U I D E Note: The very first time a QSI camera is connected to the computer it will set the relevant options shown above to default values based on the configuration of the specific camera. From that point forward, the settings are maintained in the Windows Registry. All subsequent changes are made to these Registry settings. This allows the computer to always know your last selections for each camera and restore them the next time you begin imaging.
Q S I 5 0 0 S E R I E S U S E R G U I D E Note: If only one camera is connected to the computer, the computer will always select that camera by default. You do not need to make the selection here. If two or more cameras are available and they match the serial numbers of the last camera(s) used for the Main and/or Guider camera, the computer will automatically reconnect to them in the same roles.
Q S I 5 0 0 S E R I E S U S E R G U I D E Imaging Options Camera Gain Default setting is “High”. This setting can only be changed on cameras that support switchable gain. With supported cameras, gain can be set to “Low” in order to utilize the full dynamic range of the CCD when using on-chip binning. Shutter Priority Settings are “Mechanical” or “Electronic”. This setting can only be changed on cameras with interline transfer CCDs such as the QSI 520 or 540.
Q S I 5 0 0 S E R I E S U S E R G U I D E Status and Notification QSI 500 Series camera utilizes a variety of methods to inform the operator of the camera's operation, status and other events. A built-in LED Status Indicator and audible Beeper provide notification at the camera. In the event of a serious internal error, the camera will also pass a descriptive error code back to the controlling application which then reports it to the user.
Q S I 5 0 0 S E R I E S U S E R G U I D E Camera Soft Error State Indication Flash Red: 1 Flash Yellow: 1 Flash Red: 1 Flash Yellow: 2 Flash Red: 1 Flash Yellow: 3 Flash Red: 1 Flash Yellow: 4 Flash Red: 1 Flash Yellow: 5 Flash Red: 1 Flash Yellow: 6 The camera is over-temperature. Camera has exceeded the 40°C maximum recommended operating temperature for the internal electronics and enclosure.
Q S I 5 0 0 S E R I E S U S E R G U I D E Camera Hard Error State Indication Flash Red: 2 Flash Yellow: N The number of yellow flashes of the Status Indicator specifies the nature of the camera Hard Error. This code indicates the technical nature of the problem. Note: Neither class of error indications can be disabled with the Advanced Dialog box. If you encounter any of these errors, make a record of the code flashed by the Status Indicator.
Q S I 5 0 0 S E R I E S U S E R 3 Section G U I D E CCD Imaging Overview This section is intended only as a brief overview of CCDs and CCD Imaging. If you are new to CCD imaging there are a number of excellent books that you can use to gain a deeper understanding of the issues and techniques.
Q S I 5 0 0 S E R I E S U S E R G U I D E prevent light from falling on the CCD surface while the image is being shifted out of the CCD. Interline Transfer CCDs Interline transfer CCDs work somewhat differently. In an interline transfer CCD, next to every column of pixels is a specialized storage column that is covered by a mask to prevent light from hitting the storage 'pixels' underneath. When an exposure is complete, the entire image is shifted in a single operation into this masked storage column.
Q S I 5 0 0 S E R I E S U S E R G U I D E draining off excess electrons before they exceed the capacity of the pixel. This can increase the dynamic rage of the CCD by as much as 300 times or more. This increase in dynamic range greatly reduces the difficulty of imaging bright objects. Anti-blooming CCDs make astrophotography more convenient, but with tradeoffs in quantum efficiency (QE) and linearity.
Q S I 5 0 0 S E R I E S U S E R G U I D E Single-shot color CCDs, like those found in almost all general use digital cameras, are made by placing red, green and blue filters over adjacent pixels in the CCD. The image processing program then has to separate the three different color images and recombine them into a single color image.
Q S I 5 0 0 S E R I E S U S E R G U I D E Reducing noise in CCD images CCD imagers have developed a standard set of calibration techniques to reduce or eliminate different types of noise from CCD images. Calibrating CCD images requires taking some special kinds of exposures that are then applied to the “light frames” taken of the night sky. The calibration frames are called Dark Frames, Flat Fields and Bias Frames. MaxIm LE and other CCD camera control software help gather these extra frames.
Q S I 5 0 0 S E R I E S U S E R G U I D E 6-minute Dark Frame Above is a 6-minute dark frame taken during the same imaging session with the above image of M78. Notice the brighter pixels scattered randomly around the image. Note: The pixel values in this image have been stretched significantly to show the variations in the dark frame. In reality this image is almost completely black with perhaps a few hundred “hot” pixels.
Q S I 5 0 0 S E R I E S U S E R G U I D E Original image Original image minus dark frame Look at the two images above. The top image is the original image as it came out of the camera. The bottom image has had the average of 5 dark frames subtracted from it. Note that the bright pixels have been virtually eliminated leaving a smooth black sky background.
Q S I 5 0 0 S E R I E S U S E R G U I D E The image above has been manipulated to highlight the effect of dust motes on a filter or CCD cover glass. Note the 3 darker circles. Because dust will tend to stay in one place over a night of imaging, the variation in pixel values caused by the dust can be easily eliminated by properly applying a Flat Field. A flat field is created by taking an image of an evenly illuminated subject. There are four common ways to create flat fields.
Q S I 5 0 0 S E R I E S U S E R G U I D E because flat fields tend to use fairly short exposures, you can often take a full series of flat fields and flat-darks in just a few minutes. The resulting master Flat Field is used to scale the pixel values in the light frame, eliminating the effects of pixel non-uniformity, optical vignetting and dust on the optical surfaces.
Q S I 5 0 0 S E R I E S U S E R G U I D E Stacking Images After calibrating each of your raw images with dark frames, flat fields and bias frames, combining or “stacking” multiple sub-exposures can be used to further reduce the noise in your images. Stacking multiple images with a pixel-by-pixel average or median combine tends to increase the signal to noise ratio (SNR) of the combined image.
Q S I 5 0 0 S E R I E S U S E R G U I D E of diminishing returns. Combining 18 frames will not yield a final image twice as good as combining 9 frames. Also note that in some cases, doing a “median combine” rather than an “average combine” may yield better results. A median combine is recommended if several of the individual frames have unique anomalies such as bright pixels caused by cosmic rays, satellites, airplanes, etc.
Q S I 5 0 0 S E R I E S U S E R 4 Section G U I D E Taking Images with your QSI 500 Series Camera Launch MaxIm LE Note: This section uses MaxIm LE as the camera control application. If you use a different camera control application, it will support similar operations. Launch MaxIm LE by double-clicking the MaxIm LE icon on your desktop or select “Programs > MaxIm LE > MaxIm LE” from the Windows Start menu.
Q S I 5 0 0 S E R I E S U S E R G U I D E Camera Control Window Select “Camera Control Window” from the View menu to open the Camera Control Window. MaxIm should open the window and display the Setup tab. If another tab is displayed, click the Setup tab. MaxIm may recognize your QSI camera and automatically show it as the default camera in the Main CCD Camera field.
Q S I 5 0 0 S E R I E S U S E R G U I D E If you don’t see “QSI Universal” listed in the Main CCD Camera field, click the “Setup” button in the upper left corner under Main CCD Camera. The window below will open. Select “QSI Universal” from the pop-up menu. Click OK. That will take you back to the Camera Control Window. Click the “Connect” button to establish communication between MaxIm and your QSI camera.
Q S I 5 0 0 S E R I E S U S E R G U I D E Cool the CCD To set the CCD cooling temperature you must first turn Cooling on by clicking the “Cooler On” button just to the left of the Connect button. After turning cooling on, the Camera Control window will look like this: The camera will immediately begin cooling the CCD to achieve the current setpoint temperature. To select a different setpoint temperature, click the “Cooler” button at the bottom left of the Main CCD Camera field.
Q S I 5 0 0 S E R I E S U S E R G U I D E Note: Please refer to the Cooling the Camera discussion in Section 2 Camera Features and Controls for in-depth information on cooling your 500 Series camera and the available cooling options. Focusing with MaxIm LE Achieving precise focus is critical for producing high quality astronomical photos. This seemingly simple task is surprisingly difficult when using the long focal lengths typical of astronomical telescopes.
Q S I 5 0 0 S E R I E S U S E R G U I D E Focus tab window should be set as shown above. You may need to adjust the exposure time in the “Seconds” field to the time necessary to see a few bright stars. Setting the exposure time as short as necessary to see a few bright stars allows you take more focus images in a shorter period of time, generally allowing you to achieve reasonably sharp focus fairly quickly. When you are satisfied with the focus, click “Stop”.
Q S I 5 0 0 S E R I E S U S E R G U I D E View the image in MaxIm LE When an exposure has completed, MaxIm will automatically download and display the image in a new window. After downloading the image, examine it to see if the target is properly framed and the exposure time is appropriate. The best astronomical images are achieved when the full dynamic range of the CCD is utilized. If you like the image, save it by selecting “Save” from the File menu.
Q S I 5 0 0 S E R I E S U S E R G U I D E minute image. Tracking errors, improper polar alignment, airplanes, satellites, and cosmic rays all conspire to make it difficult to be successful with very long exposures. Plus it’s a lot less frustrating to throw away one 5-minute exposure out of a total of 12 than a single 60minute exposure. MaxIm makes taking multiple sub-exposures easy. It’s even possible to set up an entire night of images and then go to sleep.
Q S I 5 0 0 S E R I E S U S E R G U I D E The Setup Sequence window allows you to set up 16 different groups of images to take during a single automated sequence. In the window above, we show 6 different steps in the sequence. MaxIm LE will take five 360 second light frames each with the red, green and then blue filters, ten 360 second light frames with the luminance filter, 12 360 second dark frames and 16 bias frames. The total duration of the sequence is shown along the bottom under “Duration.
Q S I 5 0 0 S E R I E S U S E R G U I D E The above numbers represent the minimum of each type of frame you should use. Taking more of each type of frame will further reduce the noise present in each calibration master image and improve your final results. Why you take different types of image calibration frames was discussed in some depth in the CCD Imaging Overview section. This section covers how to take the required calibration frames.
Q S I 5 0 0 S E R I E S U S E R G U I D E taken with the CCD at the same temperature as your light frames. If you’re taking LRGB or other filtered images, ideally you should take a set of flat fields through each filter. Setup your telescope and possibly your light box to take your preferred style of flats. Adjust the exposure so the average pixel is filled to approximately half its full well depth. With QSI 500 Series cameras you should strive for pixel values of roughly 30,000 ADUs.
Q S I 5 0 0 S E R I E S U S E R G U I D E Dark frame showing two cosmic ray hits in lower right hand quadrant Inspect your dark frames for cosmic ray strikes or other anomalous pixel groupings. The dark frame above shows two cosmic ray hits in the lower right quadrant of the image. Cosmic rays are energetic particles originating from somewhere in space.
Q S I 5 0 0 S E R I E S U S E R G U I D E Screenshot showing Pixel Math command ready to subtract a master dark frame. Select your light frame for Image A at the top and your master dark for Image B. Select “Subtract” for the operation. Click OK. You should see many of the bright pixels scattered around the light frame, disappear or get visibly darker. Do this with each of your light frames. After dark subtracting the individual light frames, the light frames can be combined into a master light frame.
Q S I 5 0 0 S E R I E S U S E R G U I D E 1. Produce a master dark flat following the steps above for creating a master dark frame. 2. Subtract the master dark flat from each of the flat fields. 3. Produce a master flat field by averaging the dark-subtracted flat field images. 4. Finally, divide the master flat field image into each of the dark-subtracted light frames. Save the resulting images with names that identify the frames as dark subtracted and scaled by a flat field.
Q S I 5 0 0 S E R I E S U S E R G U I D E Launch MaxIm LE. Choose “Set Calibration” from the Process menu. That will open the Set Calibration window. By default, MaxIm expects to calibrate images with bias frames, dark frames and flat fields. For this example we’re only going to show calibrating with bias frames and dark frames. Note: MaxIm also has a Calibration Wizard that steps you through the process of setting up your image calibration.
Q S I 5 0 0 S E R I E S U S E R G U I D E In the “Auto-Generation” panel near the bottom of the window, click the “…” button to the right of the text field and navigate to the folder that contains your images. In this example the images are contained in: My Documents\QSI\Astro Images\M78 QSI 504 060924\ Click the checkbox next to “Include Subfolders” if you’ve organized the images and calibration frames into subfolders within the main folder.
Q S I 5 0 0 S E R I E S U S E R G U I D E The upper panel lists the groups of calibration frames that MaxIm identified. The first calibration group should be selected. The lower “Group Properties” panel lists the files in the selected calibration group. Click on the group labeled “Dark1” in the upper panel to see the files in that group.
Q S I 5 0 0 S E R I E S U S E R G U I D E If MaxIm correctly identified all the calibration groups you created, you can click OK to close the Set Calibration window. Optionally you can click the “Replace w/Masters” button next to the Auto-Generate button. When Replace w/Masters is pressed, MaxIm will combine all the images in each calibration group and save the combined master image in the same directory as the individual frames. It will then modify the calibration groups to use each master frame.
Q S I 5 0 0 S E R I E S U S E R G U I D E MaxIm will apply each of the calibration groups you specified in the Set Calibration step to each of the open images. You can then choose to save the calibrated images or just leave them open in MaxIm. Tip: Be careful when saving the individual calibrated images not to overwrite the original image files. It is often useful to go back to the original uncalibrated images.
Q S I 5 0 0 S E R I E S U S E R G U I D E The dialog box above will open showing a list of all currently open files on the left. Select individual image files and then click the “>>” button to add them to the list of Selected Images or click the “Add All” button to add all the images. Click OK. This brings up the Combine Images dialog, which performs two related functions. It aligns and then combines the individual images.
Q S I 5 0 0 S E R I E S U S E R G U I D E The first image file is again the top window in MaxIm. Select a second alignment star near the opposite edge of the image. Repeat the process by clicking on the second star in each image. When you click on the star in the last image, MaxIm will make a bell sound indicating that the alignment process is complete. Make sure the Output field is set like you want: Sum, Average or Median.
Q S I 5 0 0 S E R I E S U S E R G U I D E If everything was done correctly the calibrated and combined image should show additional detail with less noise and greater contrast than the individual frames. Changing the range of displayed brightness levels in Screen Stretch window will show additional detail in different parts of the raw image file. Save the image with a name that allows you to identify this image as a combined master image. MaxIm provides additional tools for manipulating images.
Q S I 5 0 0 S E R I E S U S E R G U I D E Select the binning mode for a single exposure in MaxIm LE on the Settings tab of the Camera Control window. Note: MaxIm automatically adjusts the Width and Height fields to represent the size of the resulting image. In the example above 2x2 binning has been selected. This reduces the size of the resulting image of the QSI 504 from 768x512 to 384x256.
Q S I 5 0 0 S E R I E S U S E R G U I D E Note: When using binning other than 1x1, the pixels are combined inside the CCD before reading and converting the combined pixel charge to a numeric value. This results in lower overall noise than reading each pixel separately and combining them numerically in your computer..
Q S I 5 0 0 S E R I E S U S E R G U I D E Using the internal Color Filter Wheel Some QSI 500 Series cameras include an internal 5-position color filter wheel. The color filter wheel is controlled automatically by MaxIm LE or other camera control software. From the factory, the 5 positions of the filter wheel come with the following filters: 1. Red 2. Green 3. Blue 4. Luminance 5.
Q S I 5 0 0 S E R I E S U S E R G U I D E Shutting down your camera QSI cameras can safely be turned off by removing the power cable at any time, however it is best to let the temperature of the CCD rise close to the air temperature before removing power. Click on the Setup Tab in the Camera Control window. Click the Cooler Off button to turn off the CCD cooler. The fans will continue to run dissipating heat from the thermoelectric coolers.
Q S I 5 0 0 S E R I E S U S E R 5 Section G U I D E Guiding The QSI 500 Series camera can be used as you main imaging camera or as an autoguider. MaxIm LE supports the following cameras as autoguiders. Other camera control software, such as MaxIm DL support additional autoguiders with a QSI camera.
Q S I 5 0 0 S E R I E S U S E R G U I D E Using an AutoGuider This section provides basic instructions on how to use your QSI 500 Series camera as your main imaging camera and set up a separate camera on a guide scope for guiding. For this example, we’re using a Meade DSI Pro as the autoguider. For complete instructions on guiding, including a step-by-step tutorial, please see the Online help in MaxIm LE. Setup your QSI 500 Series camera as described above.
