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.
Cons
Nem tapasztaltam.
Summary
Én nagyon elégedett vagyok vele.
