Great image. Quick question about different exposures in DSS, do you just stack them all in the same processing run, so lights of varying exposures, bias, darks etc all in one go?

Thanks.

I add all the images in one stack, with flat frames and bias frames, We have found darks not beneficial with Alt-AZ mounts. I have not tried layering stacked images yet.

Adding short exposures helps with brighter parts of objects, example M42 with 60s and 10s subs, all stacked in one process, after stretching with ST, using photoshop express I can reduce highlights and increase shadows to bring out good detail in the core.
