The mono data from the DSI should give the QHY8 images a nice luminance!
I like this image of M83.. The DSI's inset frame size is a little noticeable in the upper right hand area of the shot.. however its not too distracting..
I do think its about time you dipped your toes in the QHY8 imaging waters though Allan. 6mp noise free images will really open your eyes!
