Coma corrector: for sharp stars, to the edge of the field of view

A coma corrector for Omegon astrographs and telescopes up to f/4! Astronomy photographers are familiar with the fact that photos of the night sky taken with a fast Newtonian telescope will show stars near the edge of the photo elongated. This is a typical property of fast telescopes. This coma corrector can be used to make beautiful photos of your favorite objects that everyone will admire.

The benefits in a nutshell

coma corrector for astrographs up to f/4

for a 2" focuser

Wider usable field of view

take photos that look even more impressive

M48 thread, for optimal illumination of larger sensors

also suitable for visual observation

75mm back focus

The 'meteoric' stars at the edge of its image field are the fault of an aberration known as 'coma', where off-axis points appear distorted. The solution: Omegon's coma corrector.

This ensures fine, sharp stars right at the edge of the image field: you no longer have to crop your photos and make use of a wonderfully wide field of view.

How to use the comma corrector for better photos

The coma corrector consists of two parts: the eyepiece adapter and the lens system. For photography, simply unscrew the eyepiece attachment and insert the coma corrector into your 2" focuser. Now connect the M48 thread with your camera. The advantage: even the largest chips are fully illuminated.

What do you need to optimally connect your camera to the coma corrector?

an M48 to M48 adapter between the camera and the lens system

the coma corrector requires a distance of 75mm between the lens system and the camera chip. You will need an extender to achieve back focus (minus the distance to the sensor). Example: Most SLR cameras have a sensor distance of 55mm. So you still need a 20mm extender.

Visual observation of sharp stars

You can also use the visual coma corrector to enjoy super-sharp stars all the way to the edge of the eyepiece field. The coma corrector has a 2" eyepiece with a compression ring and two set screws.
