same target but on multiple nights with different times, 60s , 180s, etc.., and different flats & flat darks. This is a game changer for me if we can do it all in one shot preprocessing.

Looks good! I'll checkout sharpless 2 catalog and find better suited objects. Once done, I'll send you data again. May I ask what the steps you took to get the jpeg you sent?

Am new. Still learning which DSOs emit stuff that I cna pick up. Is there a list of H-alpha or O3 or anything like that I can use to then determine which targets to shoot with this quad band filter? Oh, I've got a master dark, master flat, and more lights if you want to process it some? If so, do you have a recommendation where I can send it/store it for you?

awesome. looking forward to your results and recommendations. Matthew On Fri, Jun 19, 2020 at 12:51 PM han.k han59@users.sourceforge.net wrote: I got the image. This is a reflection nebula.
