And a failure. This is not really HR, or at least it is far bellow the result i could get from this amazing optic. Several reasons led to this result : tilt induced by a loosy 2" extention tube, poor seeing (but good transparency) and some wind.
Processing has been a pain in the neck due to some distortion probably caused by the Paracorr making the mosaic assembly layer by layer impossible. I had to mount the whole LRGB picture in MaximDL, and then separate each layer in PS, thus loosing some resulution in the process.
So i just present the 70% mosaic, not the full one. The overall picture is still quite pretty to me !
