This is a 70mm diameter 4 piece ED Glass full metal construction unit using premier quality Japanese ED Glass. It screws directly to the Sky Rover focuser at one end, and to a 48mm Canon or Nikon T Mount at the other, or via it’s 48mm male thread direct to your CCD Imaging train system.
Imaging Circle Diameter with Reducer Flattener fitted is 42mm and Backfocus distance from the end of the thread of the 48mm connection is 54.8mm.
This exceptional custom engineered premier quality accessory reduces the telescope’s focal length by a factor of 0.8X enabling a major increase in speed and also full field-edge correction and an a major increase in optical speed thereby shorter duration images proving the improvement in Signal to Noise performance that every astroimager seeks.
Use in conjunction with an Astronomy Alive 48mm thread Canon or Nikon T Mount to direct connect to your Canon or Nikon DSLR.
