TS-Optics NEWTON Coma Corrector 1.0x Riccardi Design - 3" Connection
3-element Newtonian coma corrector for Newtonian telescopes from f/3 to f/6 with the best illumination of its class.
? Short design with only 99 mm length for a better illumination than with all other Wynne correctors. Full frame format is not only fully corrected, but also fully illuminated.
? 65 mm working distanc for enough space for all adaptions.
? M68 ZEISS level threaded connection - with this, the entire M68 adapter range is open to you.
? The corrector works without changing the focal length.
? The corrector needs a focus position at 150 mm above the tube - that is less than with all other Wynne correctors and keeps the secondary mirror small.
? Designed by the world-famous optics designer Massimo Riccardi - a high-end corrector of the reference class.
TS Optics 3" Wynne Newtonian Coma Corrector with improved illumination
Teleskop Service has commissioned the well-known optics designer to develop further the proven Wynne coma corrector design. The problem of all Wynne correctors is the illumination. Due to the length, the field lens of the corrector vignettes. Thus 3" Wynne correctors even do not achieve 30 mm fully illuminated field at f/4.
The result of this development is the TS 3" Wynne corrector with significantly illumination and, at the same time, outstandig sharpness over the field. Thus cameras with full frame format sensors and even large format sensors can be used. Simultaneously, we were able to increase the working distance to 65 mm for making possible to use nearly all common CCD and DSLR cameras.
An overview of the advantages and features of the TS 3" Wynne corrector:
? Through the short construction of less than 100 millimeters, the illumination is significantly improved, compared with other 3" Wynne correctors.
? The corrector fits directly to 3" receptacles of focusers - the adaption is very simple.
? Through the practical M68 connection thread, screw connections with the focuser via custom adaption are just as possible as directly attaching of our M68 adapter range, like our M68 off-axis guider.
? The corrector is at least equal to conventional long Wynne correctors.
? A high-quality multi-coating is applied to every lens. Even with bright stars, no refections or ghosting will appear.
? The body is CNC machined and offers a neat internal blackening.
