0.9x SKYWATCHER Reducer/Flattener for EVOLUX 62ED
Two-element design incorporating an ED element. Reduces the standard focal length of the Evolux-62ED by a factor of 0.9x and provides the highest quality edge-of-field correction.
The flattener/reducer illuminates a full-frame format and provides accurate stellar images in a 30mm image circle.
Provides a focal length of 360mm and f/5.8. Field of view 5.09°.
Rear focus 55mm. Multi-coated. Supplied with adapter/field rotor. Filter thread inside the adapter to mount 2" filters. Thread M56x1 female / M48 male.
Can be used in conjunction with Canon or Nikon M48 T-ring adapters.
This accessory is necessary because refractors provide a curved focal plane, as stars are not point-like near the edges in the image. It provides an image corrected to the edge of the field. A dedicated adapter will allow you to attach the reducer/corrector to your telescope's eyepiece holder, it is rotatable to optimize your framing and accepts 50.8mm filters. Optimized for the Sky-Watcher Evolux 62ED f/6.45 (Doublet), this screw-in reducer/corrector reduces the scope's focal length by a factor of 0.9x (f/5.8 induced focal ratio - apparent field 5.09°).
The use of a focal reducer in astrophotography also reduces exposure time. It will be necessary to use a dedicated M48 wide field T-ring for your camera, available for Sony (#SKWSW0187), Nikon (#SKWSW0188) or Canon (#SKWSW0189).
Technical specifications of the Sky-Watcher 0.9x reducer/flattener for 62ED:
- M56 female threads on telescope side
- M48 male thread on camera side
- Image circle size corrected by 30mm
- Backfocus: 55mm from the M48 thread
