I’m still going over old data to work out how to do things properly next time. This one is M31, 71 subs at 3-minutes per sub on the Hyperstar 4 with the 2600MC Pro OSC CMOS camera. The core is blown even with just 3-minutes at f#2, and the outer arms are nothing to write home about either. But that’s OK it tells me what I need to do to get the “definitive” image from my location. I will need to take a ton of 10-minute subs to get detail in the outer arms, and as you can see from this image, I also need to make a 2-frame mosaic in order to get the whole thing in the frame. Then on top of that I will need to take a bunch of 1-minute subs (or whatever it takes not to blow out the core) to paste over the deep image and get a non-blown-out core. Keep in mind that the above image is only 3 and a half hours of data and in the upcoming “new area” that is peanuts in terms of total exposure time. All I need now are some clear skies.
