FIRST LIGHT of my new telescope (failed attempt)
Hi everyone! Sorry for the quality of the final image, it turned out to be really bad! There are several reasons for that: 1. Iris nebula's surroundings are very faint so they need an especially good signal-to-noise ratio in order to reveal themselves during the post-processing. My stacked image contained that kind of noise that forms a stripe pattern and it's almost impossible to remove. 2. I didn't do dithering, basically violated the rule "Dither or die" 🤦♂️. To be honest, I don't know how would I get away with it for all that time that I didn't use dithering... Anyway, I swear I won't ever not dither again xD 3. I didn't do proper darks after the session, trying to use my old ones, but they were taken with a different sensor temperature. So don't be me, always invest time in a proper calibration! If you're tight on time as I was, better to have less but properly calibrated and dithered images than a lot of ruined by noise data. No post-processing can fix that! Anyway, the rig performed really well! A guiding error was mostly around 1", coma corrector was doing its job, so the stars are pretty neat at the corners as well. Thanks Miguel for the drone footage and for helping me shoot this video.
