Took these pictures last week using the ED120 with ZWO ASI120MC The first picture is a 1200 stack of Copernicus using a meade 2.5x barlow and following pictures are of clavius with and without the barlow lens. I did not go too hard on the wavelet sharpening in registax to maintain a smooth appearance. would appreciate advice on whether I might of got better results with a monochrome camera. I know it would have provided better resolution but often the seeing reduces its effect.
