CATSEYETM Collimation System Introduction |
The CATSEYE Collimation web site has been changed to a "Frames" format. If you do not see a split Frame to the left, click: Here |
The heart of the CATSEYETM Collimation System is a precision, "calibrated" REFLECTIVE, TRIANGLE-SHAPED center spot placed on the primary which is illuminated with DIRECT lighting and generates very bright & distinct visual cues for quickly determining the necessary Primary & Secondary mirror adjustments.
The spot is easily & precisely placed on the Primary using one of two size exclusive CATSEYETM clear-acetate Spotting Templates: The system is readily used in daylight, but literally "shines" during NIGHTTIME collimation. When a bright red LED flashlight is directed toward the Primary from the front of the scope, with the CATSEYETM or BLACKCATTM Cheshire in the focuser, the images of both the spot and the reflective ring on the business end of the CATSEYE/BLACKCATTM can clearly be seen.
The primary mirror is then adjusted until each point of the triangle just "touches" the inside radius of the ring image (i.e. the triangle is perfectly centered in the ring). If the vertex points of the REFLECTIVE TRIANGLE center spot have been aligned with the (3) Primary cell adjustment screws at spotting, you will quickly learn which Primary adjustment screw(s) to turn and the direction to turn them.
Additionally, with the REFLECTIVE TRIANGLE center spot on the Primary, Secondary Mirror collimation using a traditional "autocollimator" or the new 2" INFINITYTM is so easy, it's scarry. When the CATSEYE/BLACKCATTM Cheshire and an autocollimator are used alternately and progressively to collimate both the Primary and the Secondary .....
