|Canon T5i on EQ1 mount stacked in DSS, 159 subs, 28 darks, 25 bias, 20 flats, ISO 1600, f/5.6, 300mm, 13 sec, total exposure time about 27 minutes|
|It feels amazing to look back on my improvement over the years - I remember being excited about each of these images at one point and now they seem so basic!|
I have a lot to learn in processing, but I did make some major progress using flats at my EQ mount for the first time on Orion. Yes that's right! Flat frames! I found this article by BudgetAstro to be the most helpful, because I didn't realize the goal of flat frames is to get the histogram in the middle - unlike dark frames where you just slap the lens cap on and use the exact same settings. I tried using flats before but just used the same settings like dark frames and massively over-exposed my flats, which is pretty pointless because then no gradient or vignette remains.
|Me taking flat frames in my family room, trying to get the histogram just barely to the left of center. Adjusted exposure time and kept f-number, focus, and ISO the same as my light frames.|
|Tried to get the screen as close to the lens as possible, and moved it around slightly while snapping frames to try to get even lighting|
More gray November skies in the forecast, maybe I'll get some more time to practice my Photoshop curves - but either way I'm extremely proud of my big leap forward in M42!
