I have a project in mind that I believe would be best suited using HDR technique. I know how to set up the imaging run using APT thanks to a thread I found here. I was wanting to know about stacking and post processing. I am assuming that you would stack each set of exposures separately, with their own respective calibration frames then combine the resulting images in whatever application you're using. I'm currently using PS as I have a vested interest in it now other than the monthly fee and I learned how to combine the HDR exposures in it. Is there any other software out there that does it better than PS that is either free or a reasonable cost?
How many different sets of exposures is really needed? My current project is the Seven Sisters, I want to capture the reflection nebula around them as well. I believe the 120 second run I have is good for the stars themselves but it does very little of the nebulas, How much longer of an exposure would I want to capture the reflection nebula and how many different exposure settings would I want?
Thanks for any and all input!
