Starlight Instruments 1:10 micro reduction for Celestron CPC, SC and Edge HD 1100
Allows more precise focusing, for example for astrophotography
The Celestron Schmidt Cassegrain's focus is adjusted by adjusting the main mirror. The normal setting is not fine enough for many applications. Focusing in astrophotography often becomes a game of patience.
The 1:10 micro reduction solves the problem. The gear reduction simply mounts to the telescope's focus drive. The accessory is not complicated, there is no need to disassemble the telescope.
