♦ Reduction of the focal length 0.79x - exposure time goes to 62%

♦ 3-element design with ED element for very good field correction

♦ Easy telescope adaptation with 2" nosepiece

♦ M54x0.75 external thread for screw connections available

♦ On the telescope side M48x0.75 female thread for 2" filters

♦ Easy camera adaptation via T2 - M42x0.75

♦ Perfect definition and good field illumination for cameras up to 30 mm sensor size

The TS 2" PHOTOLINE 0.79x corrector / reducer is an improved design of the well known Riccardi reducser.

Its four element design offers good field correction superior to cheap 0.8x reducers.

For friends of screwed solutions, an additional M54x0.75 external thread is available at the end of the 2" socket. Many focuser already have a corresponding internal thread. Via adapters you can also adapt the TSRED279 to focuser with other threads.

Back Focus - distances from the T2-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
