DrRobin Posted August 4, 2016 Share Posted August 4, 2016 Hi, I am not sure what went wrong with my flats this morning, but as it was an early rushed session I didn't notice. Even if I had there wasn't time to re-do the 12 pane Ha mosaic. Coupled with a slight lack of time, the sun struggling to rise above the villa (I moved three times to follow a gap) and an almost flat battery on my lappy (needed a re-charge to do the Ha) it wasn't going my way this morning. Ha, 12 pane disc, Quark, WO ZS80mm, 0.5x FR The bright and dark patches are the result of a poor flat and repeat in nearly every frame. I tried cropping it out of the panes, but it wouldn't stitch. Still the fili-prom in the 2 o'clock position looks good False colour Over-exposed to see the prom My Quark is not the best for proms and reckon this would have been spectacular from here with my Lunt 60. To complete the picture a full disc CaK, fortunately this doesn't need flats. So all in all a pleasing session, especially as it was crammed in to about 30 minutes. Tomorrow will hopefully be better prepared, the lappy is going on charge now and I have given my scope, Quark and camera a good talking to about flat fields.
