Hello all, thank you for your patience and time, I have reduced my workflow to be very simple and rapid when working with hydrogen alpha images of our local star taken with a monochrome sensor and how I generate the display image from the data to the display image I post and share.
I captured data today, 100mm F10 solar scope with an ASI290MM (2.9um pixels) at around 1A narrowband 6562.8A hdyrogen alpha. I captured 1,000 frames in mono 8-bit rapidly. Seeing was ok, between 1.5 arc-seconds to 2.5 arc-seconds during this capture. I stacked several iterations of frame counts but ultimately kept the 181 frame count and processed it.
I acquired the data using FireCapture. I used a synthetic flat frame during capture that I created by defocusing on the center of the disc, and then generating an exposure that filled the histogram to 65% approximately. Then I generated the Flat Frame with FireCapture's automated process and it's automatically applied to the video feed real time. I then re-focused and adjusted exposure to fill the histogram to around 65% to 72%. No gamma is used during capture, the data is there regardless.
The Software I used was mostly free except for Photoshop (CS5.1 is my version, very old as I own it). Massive credit and a huge thank you to the authors of the Autostakker!3 and IMPPG softwares, as I use them heavily and they are excellent and efficient for this process. That's it, three programs!
The rest of the information is in the video. Forgive any spoken errors or mistakes, this is not my day job and I'm human. Hopefully it gives you a rapid look into a very polished workflow. I chose to work at a smaller image scale with a 100mm aperture during the day as it would be more likely that more people could experience this or similar. If I made any grave errors, by all means, please let me know as I'm always happy to learn or correct anything I have slipped up on or misrepresented.
Thank you all for taking the time to comment on my previous video and ask for an update to processing single shots with limb and surface together. I hope this sheds light on processing it.
