Large Chip flattener for 2.5” focusers - 48 mm attachment
This flattener is made for our f-7 refractors. It threads to the rear of the 2.5" Stellarvue or Feather Touch focusers. 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. When using a CCD astro camera, spacer rings and/or extension tubes may be required.
