The Skywatcher 120ed Flattener 0.85x Focal Reducer is a useful accessory for astrophotographers who want improved field edge correction. This feature helps optimize most regular telescopes for use in astroimaging. The focal reducer also decreases the focal length of the telescope which is an advantage when taking pictures through telescopes.
You’ll need to use a Skywatcher DSLR-M48 Ring Adapter to connect this to your telescope. As always, try to make sure you’re the telescope and tripod you’re using can support the weight of your camera.
