Correctors

To correct the field of view ASA uses the Correctors designed by Dipl.Phys.Philipp Keller. All correctos have sufficient backfocus to be connected to all popular camera systems.

Given the matching corrector the system can be used as f 3.6 or can be shortened to f 2.75 or extended to f 6.8. The photographer can decide which focal length to use, which depends on the situation (object, seeing, wind ....)
This feature is only offered by the Astrographs of the N-Series but not by the Astrographs of the H-Series.

Example: an ASA Astrograph N 8"/f3.6 with 730 mm can also be used as 558mm f 2.75 or as 1380mm/ f 6.8 (see at correctors).
All our correctors are available as a stand-alone and can be used with other Newton telescopes too.
