This is a dedicated Skywatcher ED100 0.85x Focal Reducer/Corrector specifically designed for use with a Skywatcher Black Diamond ED100 telescope.
This is designed for serious Astroimaging. This unit is custom engineered & optically optimised for use on a Sky-Watcher Black Diamond ED100.
This superb quality accessory effectively reduces the telescope’s focal length by a factor of 0.85x to 765mm, and increases photographic speed from f9 to f7.65. It provides much improved field-edge correction and an 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.
Supply includes full Skywatcher Australian warranty.
