TS-Optics RC 203 Pro OTA

This 203 mm Ritchey–Chrétien uses hyperbolic primary and secondary mirrors with 1624 mm focal length at f/8. The all-reflective optical layout is intended for imaging and can also be used visually with suitable accessories.

Focusing and spacing

A separate focuser moves the eyepiece or camera without focusing by shifting the primary mirror. Extension rings are used to accommodate different optical trains. The table labels backfocus from the focuser socket separately from any distance measured from the rear tube surface.

Tube and mounting

This is the metal-tube configuration. Its published weight, secondary obstruction and mounting rails remain specific to this version; carbon and metal RC assemblies are not interchangeable specifications.

Manufacturer details

Metal-tube 8-inch RC. 8.25 kg includes focuser, with an additional 500 g for extension tubes; carbon mass/rail configuration not substituted.
