Large Chip flattener for 2.5” focusers - 48 mm attachment
This flattener is made for our 102 mm to 130 mm f-7 refractors. This includes the doublets and triplets. It threads to the rear of the 2.5" focuser (Stellarvue or Feather Touch). This flattener uses an over-sized 48 mm camera attachment thread. Using one of the over-sized 48 mm T rings, a DSLR camera may be used with this field flattener. This provides a completely threaded mounting solution for larger chip cameras when used a 2.5” focuser. This field flattener requires 55 +/- 0.5mm (standard DSLR) back focus. When using a CCD camera, the remaining back focus required can be made up with 48mm extension tubes.
48mm x .75 pitch threads can be added internally to this field flattener to accommodate most 48mm filters. Check the option box above to add this feature. SKU:SFF3-25-48Width:10.00 (in)Height:6.00 (in)Depth:6.00 (in)Shipping:Calculated at Checkout
