Hi,
Another one of AR2699. This was taken with the 80mm f/6 - Quark - Focal Reducer and ASI-120MM-S.
Did not use a tilt adapter, to see how bad NR's were going to be. They were there and after the flat still shining thru a bit. That was remover in software with Fast Fourier Transformation method.
Not as sharp as I would like, but this AR is to nice. It seems sharper on the left side, than on top right, and that puzzles me a bit. Looks as if the sensor or focal reducer are not lined up. Or is this just stacking with some better areas in some places of the image? Any ideas? Rgrds,
Paul
