Starizona 0.63x SCT Corrector IV for Schmidt-Cassegrain telescopes

Starizona Field Corrector and Focal Reducer 0.63x for all Schmidt-Cassegrain telescopes

We have tested many correctors for Schmidt-Cassegrain telescopes and this corrector has become the test winner. With this corrector, serious astrophotography of nebulae, star clusters and galaxies with Schmidt-Cassegrain telescopes becomes a success. The image quality even in the corners improves dramatically and the exposure time decreases to 40%.


That well works the Starizona corrector compared to standard f/6.3 reducers:

Thze image shows the stars at the edge with a Canon EOS full-frame camera. With the Starizona corrector, the stars are finer, smaller, and the limiting magnitude improves.

The effect is visible even with smaller sensors. Currently, we do not know a corrector with comparably good properties at the Schmidt-Cassegrain.

The advantages and features of the Starizona SCT 0.63x corrector:

Focal length reduced to 0.63x

27 mm illumination at optimal correction

2" barrel size

Suitable for all Schmidt-Cassegrain telescopes from Celestron and Meade

90.3 mm working distance

Filter thread for 2" (48 mm) filters

Camera side thread: T2 (M42x0.75) male thread

Fully multi-coated for maximal contrast - no reflexions from bright stars

Made in USA

Connection to the telescope and adaption at the camera side:

If you use a Schmidt-Cassegrain telescope for astrophotography, we always recommend an additional focuser. Focusing becomes more accurate and also more easy. The Starizona SCT corrector is simply connected via the 2" receptacle of the focuser.

You have 90.3 mm working distance from the camera-side connection thread of the corrector to the optimum focus position. This is enough space for an off-axis guider, filter wheel and, of course, DSLR cameras. A T2 extension with 35.5 mm travel is also included, giving you a working distance of 55 mm - ideal for simple adaptations.

Question:
How do you have to measure the working distance?

Answer from Teleskop-Service:
The working distance is measured from the beginning of the connection thread on the housing of the corrector (see example picture):
