Field flattener TS PHOTOLINE FLAT 3 connection M92

The TS PHOTOLINE 3" field flattener is perfect for professional Astrophotography with 3" focusers .Perfect for flattening large CCD fields thanks to its 68mm aperture.

The PHOTOLINE TS Flatteners with a 68mm free aperture have been designed for large format sensors. It corrects field curvature without altering the focal length. The flattener is screwed directly to the focuser to optimize the rigidity of the system.

The field flattener TS, apart from offering superb image quality, has another great advantage: its backfocus is significantly larger than 55mm, which is the usual value offered by most field flattener.This allows additional accessories to be used between the flattener and the camera, such as off-axis radial guides, filter-holder wheels...

Especially suitable for the following equipment:

William Optics FLT APOs of 98, 110 and 132mm (with 3.5" focuser)

Triplets TS of 102mm, 115mm and 130mm.
