Optional adapters available for 2.5" HEX focuser & 2" focuser. WitrynaThis Newton QUATTRO 254/1000 f3.9 by SkyWatcher offers a large 254mm diameter with 1000mm focal length: thanks to the fast f/3.9 focal ratio and to the compatibility with the very good optional coma corrector, it's great for astrophotography. Thanks to the not too high weight (11 kg), this Newton telescope can be used also on EQ6 type mounts.
WitrynaThe TS FLAT2 is a Field Flattener designed for use with APO/ED and Fraunhofer refractor telescopes with focal ratios f/4 to f/9. Features. Good even illumination - can be used with full format sensors; Generous back focus distance of between 108mm to 128mm - depends on the focal length of the telescope Witryna7 sty 2024 · Short focal length telescopes – especially Newtonian reflectors – exacerbate this problem, but field curvature is present in most telescopes to some extent. ... Field curvature can be corrected …
WitrynaThis turns a common f/4 Newtonian into an f/3 system, giving a larger field of view and reducing exposure times by a factor of 1.8x. The Nexus incorporates extra-low dispersion (ED) glass in a sophisticated optical design that gives performance equal to the best coma correctors while decreasing, instead of increasing, the focal length.
