SolarMax II Series ® H-a Telescopes With RichView™ Tuning 1
WARNING! Looking at the Sun can be very dangerous unless the proper precautions are taken and specialized solar viewing equipment, like Coronado Solar filters and telescopes are used. Never look at the Sun directly with your eyes. When using Coronado filters on a telescope not designed specifically for solar viewing, be sure to block all non-filtered optical components such as viewfinders to prevent the suns light from passing through.

About Coronado Coronado® was founded in 1997 by David Lunt and Geraldine Hogan as Coronado Technology Group. David Lunt’s 40 plus years experience at the forefront of optical design and innovation translated into patented technology allowing the classical FabryPérot etalon to be constructed in a novel way. Tremendous demand changed the initial concept of producing a few hydrogen-alpha (H-a) telescopes a month for the advanced solar amateur.
PST® Personal Solar Telescope Congratulations on your purchase! Meade Instruments has shipped your Coronado PST dedicated H-a telescope fully assembled and ready for use. Be sure to read the safety and cleaning instructions on page 4 and 13 before using your PST telescope. You can refer to the diagrams below for questions regarding the components of your system. Please read these instructions in full before setting up your new PST telescope and contact customer service if you have any questions.
Tuning PST Double Stack 40 with RichView tuning - With a double stack system, follow this procedure for best results: After the PST telescope is pointed at the Sun and the image has been focused, rotate the knurled ring on the telescope in either direction slowly while looking at the image in the eyepiece to get the most detail and contrast. Now adjust the tilt of the external Etalon on the front of the telescope with the T-Max wheel to achieve the brightest image while eliminating any reflections.
SolarMax II 60 Dedicated H-a Telescope filter in place. Once the nylon set screws are loose the drawtube will easily slide in and out of the focuser but cannot be completely removed. Most eyepieces will come to focus when the drawtube is nearly fully extended but some variations in eyepieces may require different positioning of the drawtube. Secure the drawtube in its new position by retightening the nylon set screws. The drawtube should be fully inserted for storage.
of 6562.8 Angstroms, you will need to adjust the tuning slightly to get the best high-contrast views of the features you want to observe. After the SolarMax II telescope is pointed at the Sun and the image has been focused, move the RichView tuning lever up or down slowly while looking at the image in the eyepiece to get the most detail and contrast. Surface details will generally require one setting, while prominences will require a different setting for maximum detail. blocking filter.
SolarMax II 90 Dedicated H-a Telescope and the helical focuser. Once the nylon set screws are loose, fully extend draw tube #2. Retighten the set screws before proceeding. To extend drawtube # 1 locate the set screws between the helical focuser and the end of the telescope. Once loosened the drawtube will extend but cannot be removed. Retighten the setscrews before proceeding.
the bandpass to <0.5Å and gives a spectacular 3D effect showing increased surface detail. The SolarMax II 90 telescope can be double stacked by adding an additional SolarMax II Etalon with TMax (Product #SME90). Contact your Coronado dealer or Meade Instruments directly for pricing. tighten the thumbscrew to secure it. Adjust the helical focuser by holding between the thumb and fore finger and rotating in either direction.
SolarMax II 40mm, 60mm and 90mm Filter Sets Congratulations on your purchase of a SolarMax II H-a filter set! Be sure to read the safety and cleaning instructions on page 4 and 13 before using your SolarMax II filter. You can refer to the diagrams below for questions regarding the components of your system. Never point your telescope at the sun until your filter set is fully assembled on the telescope.
recommends using a 1.25” diagonal and eyepiece for visual work and has provided a Zero Length Adaptor with your BF30. Some two inch accessories may not come to focus and are not recommended.
Cleaning Should your filter get a build up of loose dirt particles on any surface use a static free lens brush to gently “sweep” it clean. Fingerprints and other residue can be cleaned using a high grade optical solution applied to an optical tissue. Using a circular motion work from the outside edge in towards the center. As these are hard coatings you can be firm but do not rub. Finish with an anti-static lens cloth. All of these cleaning items can be purchased through a camera/telescope dealer.
Definition of Terms Prominences — H-a emissions projecting beyond the limb of the sun, consisting of complex clouds or streamers of ionized hydrogen above or in the Chromosphere. Filaments - Prominences seen against the face of the sun, appearing as long narrow dark streamers or diffuse dark areas. Active Region - Active regions are the result of enhanced magnetic fields and appear darker than the surrounding areas with a roughly circular shape. Active regions show plage, sunspots, and flares.
Solar Facts The Sun is on average 93 million miles (150 million km) away from Earth and 900,000 miles (1.4 million km) across. The Earth is about 8,000 miles (13,000 km) across. Think of the Sun as a basketball and Earth as pin head and you have the proper proportions. It takes a little over 8 minutes for light from the Sun to reach Earth. Approximately 1 million earths would fit inside the Sun. Solar radius =695,990 km =432,470 mi =109 Earth radii Solar mass =1.989 1030 kg =4.
Troubleshooting Here is a quick reference guide to answer some of the most commonly asked questions and solve the most common problems for the new Solar observer. I can’t find the Sun - One of the hardest things to master is lining up your telescope on the Sun. You can use a technique based on minimizing the shadow on the ground. This method will work by standing in front of and to the side of your set up.
