TS-Optics adapter to M68x1 for ASA correctors with adapter flange

Connection adapter for Baader / TS M68 ZEISS adapter system on ASA 3" correctors:

ASA offers high quality 3" correctors for Newtonian telescopes and for Cassegrain telescopes. This adapter connects these correctors to the M68 adapter system.

For example, you can directly adapt the short TS off-axis guide with M68 thread connection. Starting from the M68 thread, there are connection adapters for almost all reasonable thread sizes and up to 2".

Tilt - against oblique field:

Many astrophotographers know the problem: you focus as well as possible and the sharpness is still not satisfactory in 1-2 corners. The result is a lazy compromise, either changing the sharpness setting until the stars appear relatively evenly "sharp", or simply cropping the corner.

The M68 adapter has a built-in tilt mechanism:

The best way is a one-time calibration through test shots. Identify the "bad corner" and then begin tightening the adapter on the tension and compression bolts.

♦ Loosen the locking screws (these are the small headless screws)

♦ Adjust the adjustment screws in the orientation where you see image degradation

♦ Take the following test shot: if there is a deterioration, you are going in the wrong direction; then go in the opposite direction; if there is an improvement, you are on the right track.

♦ If you are satisfied with the result, retighten the locking screws and you are done.

.... we expect sharper astronomical images, right in the corners
