Stellarvue DSLR f/7 Photographic Field Flattener
Stellarvue SFF7-21 Photographic Field Flattener
This is our most popular modular flattener designed for the SV80, SV102, SV110 and all Stellarvue telescopes that operate at a certain focal ratio. The lens inserts into the 2" focuser and uses a tapered insert tube to more accurately seat the flattener in the focuser. A DSLR adapter is included with t-thread. The spacing distance from the T-thread on the flattener is 55 - 56 mm so it will work as is with any DSLR camera that have a t-adapter.
For other cameras including all ccd cameras, consult us. Usually, a t-thread extension is all that is needed. This flattener is designed for use with cameras having an APS or smaller chip. This is the majority of cameras on the market.
