Home. This innovative The HoTech Advanced CT Laser Collimator (patented) is a breakthrough in Cassegrain Telescope collimation! Collimate Your Cassegrain Telescope: Without using a star Indoor or outdoor - day or night Focus stays at final view setting Within focal distance from your telescope One-man operation Portable and simple to setup and use The current production model is designed to collimate telescopes with a primary mirror greater than 7-1/5-inches and a secondary mirror obstruction diameter less than 6-1/2-inches. HoTech Advanced CT Laser Collimator for 1.25" Focuser . Collimate Your Cassegrain Telescope: Without using a No For some of the mass produced SCTs, the sticky baffle on the primary mirror focusing mechanism may also cause mirror-flop. The whole process then is iterative, especially for the RC. both to keep the Hotech properly aligned (it's exquisitely sensitive) and properly oriented (needs to be used in the direction you'll be using the scope in). And during the entire collimation process, no major focusing is needed, thus minimizing the possible accumulated errors from the focusing adjustments. This alternative collimation method saves precious observing time by collimating the telescope and preparing the viewing programs at dusk or before dawn without the influences of the external environmental conditions. Ideally, it is best to collimate your optics at the same viewing focusing position without major optical displacements to correspond to the final view setting. Ideally, It is best to collimate your optics at the same viewing focusing position without major optical displacements to correspond to the final view setting. WebTelescope aperture limitation on ACT-M2 model: - Primary mirror larger than 170mm(6.7") diameter to accept the alignment lasers - Secondary mirror obstruction smaller than 170mm(6.7") diameter without blocking the alignment lasers Download Advanced CT Laser Collimator User's Manual For some of the mass produced SCTs, the sticky Setting up for collimation, you will be standing between the telescope and the collimator aiming both the Tedious work. I have one also. In order to achieve an accurate star collimation, normally the amateur astronomer requires good seeing conditions with no cloud, no wind, stable temperature, no light pollution, a well-aligned telescope mount tracking system, telescope optical tube assemble (OTA) thermal equilibrium, and a good visible magnitude star. D. Associate Professor and An artificial star can never simulate a real star because it is impossible to collimate with the telescope focus set at infinity. 1 x Advanced CT Laser Collimator. Out of Stock. Wouldnt recommend it instead of just using the stars, even in cloudy Germany. The designs have gained their popularity because of their compact and simple to produce design. It is then hardened and With different designs, star collimation is and has always been the only effective method to collimate for Cassegrain telescope owners.

The visual quality of the referencing star is greatly affected by the prescribed factors most of which are all in God''s hand as you can see in the photo. An artificial star can never simulate a real star because it is impossible to collimate with the telescope focus set at infinity. your order. The Advanced CT Laser Collimator uses three collimated lasers, evenly spaced apart, to sample large aperture optical elements in your telescope. If a mirror-flop has ocurred, it will affect the alignment position which in turn will render the collimation useless. distance. The rigid, ultra thin profile, and light-weight design makes the unit portable and simple to setup and use. The lunar shot was taken with my Nikon 995 and that Celestron comet catcher I picked up Nikkor 24-70 mm lens; ISO 200; 50 mm focal length, f/5.6; three stacked exposures, 2 minutes each, This is actually a snapshot from actual footage I took of the planet Neptune.
