This is a dedicated Sky Rover 0.8X Focal Reducer/ Flattener specifically designed for use with a Sky Rover 115mm ED Triplet APO F/7 Apochromatic Astronomical Telescope.
This unit is optimised for use on a Sky Rover 115mm ED Triplet APO F/7 Apochromatic Astronomical Telescope.
Please note this is a different selection & design to the Sky Rover ULT115 Reducer Flattener – EVERY Sky Rover telescope has a DEDICATED design Reducer Flattener – as we are firm in our attitude that every Reducer Flattener has a dedicated design, and is unsuitable to be applied to more than one specifically designed telescope’s optic – this is the only way to do this duty properly.
This is a 70mm diameter 4 piece ED Glass full metal construction unit using High 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 CMOS Imaging train.
Imaging Circle Diameter with Reducer Flattener fitted is 42mm and Backfocus distance from the end of the thread of the 48mm connection is 55mm.
This custom engineered High 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.
