Sky-Watcher 2″ Aplanatic Coma Corrector f/4

Skywatcher Aplanatic coma corrector

Skywatcher Aplanatic coma corrector for sharp stars to the edge
The Skywatchers Aplanatic coma corrector lets you get the most out of your fast Newton telescope. Stars stay nice and round, even at the very edges of your image. No more stretched dots. No more “comets.” Your pictures immediately look calmer and more professional.

Specially made for fast f/4 Newton telescopes
Fast telescopes are great for astrophotography, but they often show distortion at the image edge. This coma corrector addresses that problem at the source. It corrects the image without changing your focal length. So you keep the same field of view, but tight and sharp.

More confidence in long exposures
Because stars remain neatly point-shaped, you can expose longer without your image becoming cluttered. Details in nebulae and galaxies come out better. That means more usable photos and less post-processing afterwards.

Easy to integrate into your setup
The 2″ connection fits directly onto your Newton telescope. On the camera side, you use an M48 connection. With a 55mm back focus, it is ideal for many cameras and accessories. Everything connects logically, so you'll be ready to shoot faster.

Compact, solid and thoughtful design
The four lenses are perfectly aligned to effectively correct distortion. The compact design keeps your setup balanced. This is important, especially for precise tracking and longer exposures.
