Below is a set of 10 subexposures of 240seconds of the Dumbbell Nebula, taken with my newest addition, the GSO Ritchey-Chretien 8inch scope and the QHY8L.
Darks and flats were used, stacked with DSS, and very quick PS editing (just levels, curves and some denoise).
I am thinking of getting the PixInsight software since the trial is over and it is 10 times as good as Photoshop..
Good night and clear skies,
Andrei
