This full frame field flattener is made specifically for the aluminum tube SVX102T and the carbon fiber tube SXV102T-R. It is made specifically for the Stellarvue FSV3 3" focuser.
Please note: This flattener will not work with telescopes using other focusers.
If you are using a Stellarvue SV102T/SVR102T using a 3" Feather Touch focuser you will need this 3 inch Feather Touch focuser adapter. If you are using an SV102T/SVR102T that comes with either the Stellarvue or Feather Touch 2.5" focuser you will need our 2.5 inch focuser adapter.
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.
