Arcturus 2" Adjustable Eyepiece Proj Camera Adapter
This eliminates the need to change eyepieces when different magnification or additional projection enlargement is desired. This additional projection range is particularly useful in high-resolution Lunar / Planetary photography. The rightmost barrel can be unscrewed and is the same as the prime focus camera adapter above. Requires T-ring (sold separately - see below). Threaded to accept standard 2" filters.
