The MountOne 100MM Astrograph.

Front and centre, top, is a 100mm f/3.5 apochromatic C-Mount lens. The lens has manual iris and focus control rings on the exterior of the lens.

The 100MM Astrograph enables automatic focus control of the lens by way of a stepper motor, belt and printed focus ring. Taking advantage of OnStep's INDI Focus driver, we can remotely control and adjust the precise position of the 100mm's focal plane.

Twin 6811-2RS bearings (the same as used in the MountOne), support any tension on the belts that adjust the focus. This keeps any stresses off both the lens and the Raspberry Pi HQ Camera it attaches to.

The 100MM astrograph integrates the lens, focus system, HQ Camera, a Raspberry Pi 5 & accessories, power converter, and an optional GPS into a single unit.
