Vixen Optics offers an array of choices for mounting photographic imagers to your telescope focusers.
The #3523 43mm DX Camera T-Adapter fits any drawtube with a 43mm female threading, or anything you can reduce to that size. For telescopes with a 2" (50.4mm) inner diameter focuser/drawtube, you can use the Vixen #37291 EA 50.8mm to 43mm adapter. Many Vixen telescopes have a 60mm inner diameter drawtube, but include a 60mm to 50.8mm adapter.
A Vixen T-mount is attached with the SLR camera to the rear of this adapter, and in between it is possible to have a 1.25" eyepiece (for eyepiece projection imaging) or no eyepiece at all (for prime focus imaging). When using this device for prime focus imaging without eyepieces in the optical path, it is possible to use a 48mm filter upon the combination filter ring/eyepiece holder ring.
