The corrector is designed for this apochromat and brings optimal astrophotographic results. Cameras up to full frame can be used and the star images are pinpoint up to the corners. In addition, the focal length of the apo is reduced to 336 mm. The focal ratio improves to f/4.8, saving about 36% in exposure time over a 1.0x flattener.

The connection of cameras to the corrector:
On the camera side, the corrector has an M48x0.75 male thread. This thread provides 15% better illumination than T2. Therefore we can recommend the corrector for all cameras up to full frame. The working distance is exactly 55 mm from the thread. For all astro cameras there are suitable adapters for this thread and distance. We are happy to advise you.

Thread for 2" nebula filters available:
If you unscrew the camera adapter from the corrector, you have a 2" filter thread on the inside. There you can use nebula filters for contrast enhancement or IR cut filters. The working distance is not changed.

The connection on the telescope side:}]The corrector has an M63x1 male thread on the telescope side. Included in the scope of delivery is an adapter to the M54x0.75 thread. With this adapter, you can screw the corrector directly into the focuser of the TS CF apo. No tilting is possible and the star image remains optimal.

Adaptation of astro cameras with 17.5 mm distance from T2 thread to sensor:
Many astro cameras have a T2 connection thread and a back focus of 17.5 mm. With this adaption you have also integrated a 360° rotation, a quick coupling and still a mount for 2" filters. You need the following components, from the camera to the telescope:

• T2AbstimmA05 (tuning ring with 0.5 mm height)
• TSROTM48-T2 (adapter to M48, rotation, quick coupling and filter holder)
• TSVF208 and TSFV210
