Stellarvue Large Photographic Field Flattener for SVX80T-3SV
This is the same full frame field flattener that comes with the Stellarvue SVX80T-3SV and SV80T-3SV. The Stellarvue Large Photographic Field Flattener for SVX80T-3SV is formatted for this telescope specially and it threads into the adapter on the focuser drawtube.
This flattener will also work with the following telescopes but you need to add an adapter in order to thread it to your focuser drawtube:
- SV80ST refractors that use either a 2.5″ Stellarvue or a 2.5″ Feather Touch focuser
Please note: This flattener will not work with older 80 mm Stellarvue Telescopes that were made using a 2″ focuser.
On the camera side of this flattener is a standard M48X.75 thread. The backfocus from the base of this thread is 55 mm. So this flattener as it comes will work with a DSLR with a 48 mm t-ring. It will also work with a ccd camera that uses the M48 thread and has a 55 mm back focus. If your ccd camera uses another thread and/or if the back focus is not exactly 55 mm, please call us and we can provide you with a modified version of this flattener with the proper adapter to meet your requirements.
