TS-Optics REFRACTOR 0.79x 3" ED Reducer Corrector for big sensors

TS Optics 3-inch 0.79x ED reducer corrector for APO refractor telescopes

TS PHOTOLINE 3" 3-element 0.79x reducer offers a big well corrected and illuminated field with 45 mm diameter. The corrector is made for CCD and DSLR cameras with big sensors. Of course the results will be also perfect with smaller sensors.

♦ We suggest the corrector for all refractor telescopes with 2.5" focuser or bigger.

♦ Barrel 3" or (at least) M68 thread necessary

♦ Best multicoating and well blackened internal walls against reflections

♦ Save connection to the telescope through the ZEISS Level M68x1 male thread

♦ Simple camera adaption through the M48 2" filter thread on the camera side


 

The TS Optics PHOTOLINE 0.79x reducer / corrector

...has been designed for astrophotography through APO refractor telescopes. It makes the system faster and corrects for the field curvature even with full size sensors. It does not need the extreme back focus of the Riccardi corrector. It is suitable for all models with focusers from 2.5" and connects to them via M68 thread or 3" barrel.

Back Focus - distances from the M48 thread to the camera sensor

depends on the focal length of the telescope:

♦ Focal Length to 350 mm .... 70 mm
♦ Focal Length to 420 mm .... 65 mm
♦ Focal Length 450-500 mm ... 61 mm
♦ Focal Length 510-600 mm ... 58 mm
♦ Focal Length 610-700 mm ... 57 mm
♦ Focal Length 710-790 mm ... 56 mm
♦ Focal Length from 800 mm .. 55 mm

To find the exact distance, we offer spacer and extension rings.
