TS PHOTOLINE flattener / corrector - full size field flattening for APOs with large focusers
... exceptional results even with full size sensors - the focal lenght is not affected
... direct M48 connection for DSLR cameras

TS Field Flattener for full size sensors

This PHOTOLINE Flattener has been developed for the TS triplet and ED refractors equipped with a 3" Crayford focuser. It corrects for the field curvature without changing the focal length. The large free aperture of 68 mm allows illuminiation of full size sensors without vignetting.

The TSFLAT3 can be mounted directly to focusers with female M92x1 thread:
... these are e.g. the TSFOCR3 and the similar 3" Astrotech focusers.

We offer adaptations to all common focusers (see adapter recommendations below). The manufacturing of individual adapters is possible, too.

Scope of delivery:

TSFlat3 parts
The flattener comes with a M48 adapter. Using a M48 bajonet ring, you can attach your DSLR camera directly and achieve good results. If using full size sensors, it might be necessary to fine tune the distance with spacer rings between corrector and camera.
