Scott really knows how to process an image. He also is has a lot of patience and takes the necessary time to collect a lot of data. He is a professional photographer and he clearly has an eye for what makes a nice image. Thanks for the comments.

Thanks Dave, it is a beautiful image. Great detail, stars are solid and the color is just right.

Trevor,

I'm not sure of the total time but I do know that the Ha is 18 10 min exposures. He uses a 900 mm guide scope and hasn't seen any differential flexure. I'll see if I can get the RGB exposure time.
