ASA 500mm f/15.6 classical Cassegrain OTA soon to be installed (7800mm focal length). The baffle, focuser, secondary and primary are all independently adjustable; it took a few days to figure out the collimation but I got it. The OTA is well designed and built. The supplied documentation shows optics with outstanding Strhel figures. I should have it up and running in August of 2022.
