David Astro Adapters

David Astro adapters are the machined parts that connect cameras, correctors and visual gear in a working imaging train. The range covers M42 and M48 extension tubes from 3mm to 30mm for setting backfocus, T-rings for Sony Alpha, Pentax K and Micro 4/3 bodies, and 1.25" and 2" nosepieces to T2 or M48.

An SCT to 2" visual back lets Schmidt-Cassegrain owners use standard 2" diagonals and eyepieces.
