Hello!
I just purchased your HaRGB guide and was skimming through it. I have a couple of questions. I am fairly new to RGB as I have focused on narrowband SHO photography as I live in a Bortle 9 + area.
Why are you not using Luminance frames? I have ready pretty much everywhere its important but obviously you're getting great results without it. I do have to admit when I've tried to take luminance at 300 seconds (To match my RGB Data) it is washed out and very overexposed.
Thank you!
Bryan
Hi Bryan, I'm sorry about the late response, I've had issues with notifications on the forum for a while. To answer your question: To me, spending hours shooting in Luminance is only worth it when I know the target has very faint dust within it, a ton of intricate details, or if there is IFN in the background. Some other galaxies, like M51 or M63 do have dust so L is useful. Some others, like M74 have a lot of IFN around them so that's also useful. But for many targets, L is in my opinion not worth the trouble. As you saw in my M101 guide, the end result has plenty of details and colors without L!
