Pro Coma Corrector for Astrograph

Chromatic aberration corrector: for sharp stars right up to the edges
Omegon Chromatic Aberration Corrector for Astrographs and Telescopes up to f/4. Astrophotographers know all too well that when capturing the sky through their fast Newtonian telescope, stars close to the image edge appear elongated, rather than as sharp, round points. This is a typical phenomenon found in brighter telescopes. But now this chromatic aberration corrector will allow you to immortalize your favorite celestial objects in admirable photos.

Summary of the benefits:

• Chromatic aberration corrector for astrographs up to f/4
• Compatible with 2" eyepiece holders
• Larger useful field
• Stunning photos
• M48 thread for optimal illumination of larger sensors
• Also suitable for visual observation
• 75mm Backfocus

Meteoroid stars around the edges of the image: the culprit is an optical system defect called chromatic aberration. Light rays strike the system diagonally to the optical axis. The solution: Omegon's chromatic aberration corrector.

It ensures sharp, defined stars right up to the edges of the image. With it, you won't have to crop your photos again, but you'll also be able to take advantage of a substantially larger field of view.

How to use chromatic aberration corrector to get better photos
The corrector consists of two parts: the eyepiece adapter and the lens system. To practice astrophotography, simply remove the eyepiece adapter and attach the corrector to your 2" eyepiece holder. Then, screw the M48 thread onto your camera. The advantage: this will also illuminate larger sensors.

What is needed for a perfect match between camera and chromatic aberration corrector?

• An M48 to M48 adapter between the camera and the lens system
• The chromatic aberration corrector requires a 75 mm distance between the lens system and the camera sensor. You'll need an extension sleeve to achieve backfocus, subtracting, of course, the distance to your camera's sensor. For example, most SLR cameras have a 55 mm distance to the sensor. In this case, you would need a 20 mm sleeve.

Visual observation of sharper stars
Feel free to use the chromatic aberration corrector for visual observation and enjoy super-sharp stars right up to the eyepiece. The chromatic aberration corrector features a 2" eyepiece mount with a retaining washer and two screws.
