A Maksutov corrector is then placed just ahead of the secondary mirror (supporting the secondary and eliminating the need for spider vanes). As in a Maksutov camera, placing the corrector at the center of curvature would eliminate coma entirely, but would result in an absurdly long optical tube. Typical focal ratios range from f/4 to f/6. Skywatcher QUATTRO-8S 200 mm f/4 Imaging Newtonian with parabolic Pyrex Mirror The new QUATTRO Newtonian Telescopes from Skywatcher with the fast f/4 focal ratio are ideal for astrophotography with short exposure times. But they also deliver a good image quality for observing moon and planets.

The focal reducer function: The faintness of deep sky objects means that DSLR and CCD deep space photos can require lo-o-o-ng exposures with a long focal length telescope.For those who guide their telescope manually, long exposures invite guiding errors as …

2016-7-19 · accessories, like the F4 Coma Corrector (4 lenses, enlarged T2 thread), we advise you to ask your reseller or visit the Sky-Watcher sites at www.skywatcher.com … Skywatcher Quattro 8-CF Imaging Newtonian. February 13, When I received my telescope and optically matched Aplanatic Coma Corrector, I was impressed with the build quality of the scope itself, internal baffles to boost contrast as well as eliminate stray light, and the focuser is pretty sturdy for a stock focuser, and quite easily handles

It is quite possible I have found the best position and I'm not satisfied with it. It is also possible that the coma corrector has removed the coma and flattened the field and has now revealed an eyepiece aberration I could not see before as a coma corrector does not actually correct the eyepiece itself.

2020-1-30 · A 2? dual-speed 10:1 ratio focuser is included for excellent focusing precision. Additionally, the tube length has been slightly shortened to optimize performance for prime-focus photography. Even better performance for astro-photography, and visual use, can be achieved when used in combination with the Sky-Watcher Quattro coma corrector. The Altair Astro Photo-Visual Coma Corrector will reduce coma in most fast Newtonians, as well as acting as a field flattener, and is optimised to work with the Altair Astro 8" F4 Imaging Newtonian, as well as Synta Skywatcher, Orion USA and GSO Newtonians.

The Revelation 2" Coma Corrector for Newtonian Telescopes effectively reduces coma (elongation of stars) and field curvature defects in shorter focal ratio Newtonians of f/4 and slower. Highly recommended for our Revelation f/4 M-LRN imaging scopes. Also recommended for Skywatcher PDS systems and Altair Astro Imaging Newtonians. F5 Coma Corrector. Optimised for use with Sky-Watcher f/5 Newtonian reflecting telescopes, this field correcting lens provides flat pin point stars for both visual and astrophotography needs. Take full advantage of your full-frame Digital SLR camera and produce superb flat field images without any increase or reduction in magnification.
