This is a LRGB image of the core of the Iris Nebula, NGC 7023, shot at f/10 and 2800 mm focal length with the C11 EdgeHD and my retired Atik 383L+ camera. This image is based on data taken in 2013 that disappeared from my Astrobin account after the crash in 2018. Rather than recovering the old version, I gave the raw data a thorough re-process using modern software.
I wish I had more integration time, since I was onto something with this project. Back in those days, I had to drive to a dark site every time I wanted to image, so integration time was expensive.
Try imaging at 2800 mm focal length from a sandy field without concrete underneath, using a severely overloaded CGEM with 45 lbs. riding on it - yikes!!! How did I even get usable data for this project? Some of the subs were 15 minutes long, too. What are those spikes in my PhD graph?
I'm really hurting for new data right now, unless you want to see pictures of snowflakes accumulating on my patio. I did manage to get 16 hrs. of new data last month thanks to two really good back-to-back nights. However, I only shot luminance on some galaxy groups. Until I can get some RGB time, I'm afraid I'll be reprocessing old data and playing with gear in my basement.
