Baader Field Flatteners, Reducers & Coma Correctors

Baader Planetarium correctors fix the optical aberrations that appear at the edge of the field in astrophotography. The MPCC Mark III is a 2" coma corrector for Newtonian telescopes, the RCC I Rowe Coma Corrector serves fast Newtonians, and the M68 Field Flattener gives flat fields with refractors.

For visual use and imaging with long-focus instruments, the Alan Gee Telecompressor Mark II and UAG II shorten the focal length, with a centring ring for 9.25" SCTs.
