We either send the Antares, Celestron or TS-Optics reducer. They are identical.
Focal reduction and image field flattening for Schmidt Cassegrains
Schmidt Cassegrains are among the most popular telescopes on the market. The main reason is the compactness and, of course, the price, which is possible through the production in large quantities.
Visually, however, these devices are a compromise. The focal length is relatively long, which makes the devices faint and also the field of view is curved. This makes astrophotography difficult. The usable field of view is very small and also blurred at the edges.
Astrophotography with good results is only possible with suitable lens attachments.
What does the SC f/6.3 reducer?
Increase the light intensity ... the light intensity is increased from the typical f/10 to f/6.3. That means one reduction of the exposure time to about 40%!
Reduction of the focal length ... the focal length decreases and correspondingly larger is the usable
Facial field ... For example, the focal length of 2000mm is reduced to 1260mm.
Flattening the image field ... the curved field of view is leveled, the sharpness increases at the edge. The perfect distance to the camera chip are 85mm from the SC thread. The thread itself is not included.
Technical characteristics:
Shortening factor ... Shortening factor 0.63x - f/10 becomes f/6.3 (at 85mm distance from the camera's thread to the chip)
Lens construction ... four-line design - multi-coated for maximum light transmission
Connection thread ... telescope side SC female thread / camera side SC male thread
Many adaptation options - see "recommended accessories":
- Adapter to 2" connector ... for adapting the reducer to 2" sockets - if, for example, you have provided your SC with a 2" extension
- Celestron Radial Guider ... an Off Axis Guider that allows tracking and recording with the SC telescope at the same time
- Adapter from SC to T2 ... the SC focal adapter connects the SC male thread to T2
