TS PhotoLine 2" 0.79x 4-Eement Corrector / Reducer for Apo Refractor telescopes

TS PhotoLine 2" 0.79x 4-element corrector for apo refractor telescopes

TS Optics focal reduction and field correction for astrophotography with Apo refractor telescopes

♦ focal length reduction 0.79x - the shutter speed is reduced to 62%
♦ 4-element design for maximum sharpness performance
♦ Can be used on any refractor with 2" eccentric or larger
♦ Perfect sharpness and good illumination up to 30mm sensor diameter - perfect for DSLR cameras with APS-C sensors
♦ Easy camera adaptation via the T2 thread (M42x0.75)
♦ 2" socket with 2" filter thread

TS Optics Photoline 2" Corrector and focal length reducer for astrophotography with APO refractors

The corrector is a further development of the well-known RICCARDI Reducer. The 4-element design provides a very good correction in the field, which can not be achieved with the simple 0.8-fold reducers.

Unlike the Riccardi Correctors, this corrector can be used on any refractor with a 2" eyepiece, and if you can use a 2" level mirror, you will not have any problems focusing with the PhotoLine Reducer.

Distance T2 thread to the camera sensor

The distance depends on the focal length of the refractor:

♦ Focal length < 350mm: 70mm
♦ Focal length up to 420mm: 65mm
♦ Focal length 450-500mm: 61mm
♦ Focal length 510-600mm: 58mm
♦ Focal length 610-700mm: 57mm
♦ Focal length 710-790mm: 56mm
♦ Focal length > 800mm: 55mm
