Stellarvue Field Flattener for f/7 Telescopes with 2" Focusers - SFF7-21

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. 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..

This large photographic field flattener is made for our 102 mm - 130 mm refractors. It threads to the rear of the Feather Touch 3” focuser. This flattener is made for cameras that have the 2.156-24 camera attachment.

It is essential that the flattener be placed at a precise distance from your cameras CCD chip. This is referred to as the cameras "backfocus." A camera's backfocus is the distance from the attachment thread to the ccd chip. All ccd cameras have different backfocus distances. This distance is increased when adding filter wheels and/or off axis guiders. For this reason, we work with our customers to help them get the correct spacing. You can save yourself a lot of time and frustration by merely calling us.

This flattener works as is with the SV130 when there is about 52 mm of backfocus to the CCD chip. It works with the Stellarvue 102 when you have about 55 mm of backfocus. If you are not sure about your particular requirements please contact us at (530) 823-7796 Monday - Friday 9-5 Pacific Time so that we can assist you in getting precisely what you need.  if a custom adapter is needed to achieve the proper spacing between the field flattener and the camera, we can make this for you.
