This corrector really does the job well. The optics quality is great and the stars are sharp from edge to edge with my F4 Newtonian. Observing with eyepieces is really good especially if they are parfocal. It's not very difficult to find the optimum focus for the corrector. I have it permanently fitted in my Newton and I don't even take it out. It makes my Newton a perfect telescope without any coma. When I saw Albireo through the corrector for the first time, I was shocked by the sharpness and clarity of the view - it was like there's no any optics at all! You can also attach any camera with 42mm or 48mm thread. You can even attach the ZWO ADC corrector using the 42mm thread. The corrector looks very large on the picture, however, it doesn't reach/obstruct the optical path of the telescope when inserted into the focuser and therefore it doesn't cast any shadow on the main mirror. This is a must have for any F4 Newtonian.
