TS-Optics NEWTONIAN Coma Corrector 0.97x Riccardi Design

Codice articolo: TSWynne68

The 2.5" Wynne Coma Correktor has been completely redesigned by Massimo Riccardi and now provides full illumination with full format sensors for Newtonian telescopes.

♦ Optimal for Newtonian telescopes with an f-ratio of f/3 up to f/6

♦ Very good illumination and correction up to 50 mm field diameter

♦ Generous backfocus between 66 mm and 71 mm (depends on focal length)

♦ Adaptation to the focuser via the M68x1 thread

♦ Camera connection via the M68x1 male thread of the corrector

♦ Due to the short design the illumination is improved and the corrector requires only 160 mm distance from the tube

♦ 1st image to the left - similar, the current corrector is even shorter

TS-Optics Wynne Newtonian coma corrector for large sensors

For the correction of coma of Newtonian telescopes Massimo Riccardi has designed this outstanding 3-element coma corrector for Teleskop-Service. The corrector provides 66-71 mm backfocus for all customary CCD and DSLR cameras and also off-axis guiders, filter wheels, ... This makes the TS 2.5" Wynne corrector an interesting alternative to the ASA Wynne corrector, which offers less backfocus. On top of that, our corrector provides better illumination, achieved by its short design of only 100 mm.

Simple adaptation to the focuser via the M68x1 thread:

The TS 2.5" Wynne corrector has a M68x1 Zeiss style thread on its top. This thread permits the trouble-free screw-connection to many focusers, for example the Moonlite 2.5" or Starlight Feather Touch. The focusers only requires a camera-sided M68x1 female thread. This specific thread is very common amongst high-quality focusers.

Camera-connection and required backfocus distances:

The TS 2.5" Wynne corrector has a camera-sided M68x1 female thread. This allows for a convenient attachment of exciting accessories, such as our TS-Optics M68 off-axis guider. Most cameras with large sensors offer a M68x1 connection or can at least be adapted to this thread.

The backfocus is calculated from the base of the M68x1 thread:

♦ Focal length 600 mm - Backfocus 66 mm
♦ Focal length 800 mm - Backfocus 68 mm
♦ Focal length 1000 mm - Backfocus 69.5 mm
♦ Focal length 1200 mm - Backfocus 69.75 mm
♦ Focal length 1500 mm - Backfocus 70.5 mm
♦ Focal length 1800 mm - Backfocus 71 mm
