ASA 3" Wynne Corrector for ASA N-Series Astrographs
To correct the images produced by N-Series Astrographs, ASA uses correctors designed by Philipp Keller. All correctors have sufficient back-focus to be optically compatible with all popular astronomy camera systems.
Depending on the corrector installed, ASA N-series Astrographs can be used at f/3.6, or shortened to f/2.75, or can be extended to f/6.8. The astrophotographer can decide which focal length to use, depending on the object they are imaging, the seeing conditions, or other considerations.
For example, an ASA 8" Astrograph 8N, f/3.8 with a nominal focal length of 730mm can also be used at 558mm (f/2.75) or as a 1,380mm (f/6.8) optical system. All ASA correctors are available for purchase separately, and can be used with many other Newtonian telescopes.
