PFE-1 MOUNTING KIT INSTRUCTIONS

MOUNTING KITS FOR THE SPECTRASOURCE INSTRUMENTS CAMERAS

The Lynxx PC, Lynxx MC, Lynxx 2, and Lynxx 2000 camera heads are shipped with a

combination 1¼"/2" telescope coupler which must be removed. Loosen and remove the

coupler by removing the three socket cap screws holding the coupler to the camera face.

Install the stainless steel mounting plate with the dovetail mount away from the camera face

using the three 1/4" long flat head socket screws.

Next, attach the PFE-1 to the dovetail by tightening each of the four setscrews on the PFE-1.

Roughly center the camera by looking down the 1¼" coupler. You may need to flip the

mirror out of the way and remove the filter slider. The CCD photometer is now ready for the

reticle alignment (Section 3.3).

MOUNTING KITS FOR THE SBIG ST-4 AND ST-5 CAMERAS

To mount the PFE-1 to the ST-4, the existing 1¼" coupler with clear glass window must be

removed. Since this procedure directly exposes the CCD chip, it should only be done in a

dust-free environment. To reduce the moisture content inside the CCD chamber and reduce

the possibility of frosting, the existing 1¼" coupler should only be removed when the

relative humidity is below 50%. Carefully loosen and remove the four socket cap screws.

Gently lift the telescope coupler up and away from the camera body. This will expose the

CCD chip directly. Next, position the new camera mount with O-ring and clear glass

window directly over the CCD. Line up the screw holes and install the four 5/8" long socket

cap screws. Tighten snugly.

Next, install the stainless steel mounting plate with the dovetail mount away from the camera

face using the three 1/4" long flat head socket screws.

Finally, attach the PFE-1 to the dovetail by tightening each of the four setscrews on the PFE-

1. Roughly center the camera by looking down the 1¼" coupler. You may need to flip the

mirror out of the way and remove the filter slider. The CCD photometer is now ready for the

reticle alignment (Section 3.2).

Note: the eyepiece height is lower for the ST-4 than for the Lynxx cameras. This is

due to the fact that the TC-211 chip is actually mounted on the face of the camera head

rather than within the camera head as with the Lynxx cameras. Thus, the chip can actually be

brought closer to the flip mirror of the PFE-1. The eyepiece height is set at Optec according

to the mounting kit purchased. Do not attempt to adjust the eyepiece orientation or height.
