Quantity

This field flattener for f/7 refractors slips inside a 2" focuser. 

This is our most popular modular flattener designed for 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 has a t-adapter. For other cameras including all ccd cameras, consult us. Usually, a 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.
