More about the product

The most problem of common coma correctors that even if they improve the coma on the edges, but makes spherical aberration at the center, what degrades image sharpness and resolution. This new coma corrector has 4 lenses, 2\" size. Does not give any additional optical defect on the image (for example does not have interior reflections on surfaces that reach the image).

The focal point remain on the same place, so with a M48 adapter you can easily attach your Canon or Nikon camera. On the botoom there is a standard filter thread.

The optimal image quality depends on your telescope\'s focal length. In the below you can find the optimal distance from the M48 edge of coma corrector to the sensor.

telescope focal length	corrector-CCD distance
600mm	52,2mm
800mm	54,2mm
1000mm	55,5mm
1200mm	55,2mm
1600mm	55,2mm

The standard M48-EOS adapter has 55.2 mm distance with Canon-EOS cameras. We also have 54.2 mm adapter for 800 mm focal length, if you need that, please advise.

Pros

Már régóta vártunk egy kiváló minőségű, fókuszt nem növelő, ugyan akkor elfogadható árú korrektorra F/4-es rendszerekhez. Ez a korrektor ennek abszolút megfelel. Nem mellesleg magyar tervezésű az optika.
