3D printed RASA 8 Centering Ring Kit based on mxcopell/apshooter inspiration on CN forum. The kit replaces the uneven and too thick "Black Teflon Compression Ring" provided by Celestron for Rasa 8" telescope.
Two models included:
RASA Ring -> 87.5mm outer, 85.4mm inner diameter, 2.3mm height. Fits within retaining ring. No washer, so metal of rasa-T-ring adapter will hit metal of Clamp Ring.
RASA Ring/Washer -> 87.5mm outer, 85mm inner diameter ring, w/ 2.3mm height. washer/bearing: 87.5mm outer and 81mm inner diameter, w/ 0.6mm height.
This goes between rasa T-ring adapter and Starizona filter slider to allow filters to slide out without hitting Clamp Ring. Height of washer does not affect backfocus.
