Target: Flying Bat and Squid Nebula - Equipment used and the technical card Celestron C11 EdgeHD telescope with Hyperstar V3 Asi1600mm Pro camera with ZWO EFW (filter wheel) EQ6R Pro mount Astronomik LRGBHaO3 31mm 6nm MaxFR filters guided with 60mm 240mm fl guide scope 30 hours of total exposures (22.5 hours O3, 6.5 hours Ha, 45 min RGB) - Imaging date and place Over several days between Sep 16 and 21, 2022. My Bortle 6 backyard in Cochrane, Alberta, Canada - Briefly describe your photo story, digital processing methods employed (if any) This is the faintest target I have ever imaged. The Squid nebula (Outters 4) is located inside the Flying Bat nebula (the red region of ionized hydrogen gas). This nebula is located 2,300 light-years away in the constellation of Cepheus. The Squid is considered to be an outflow from the star system HR8119 in the center of the Squid nebula and is so faint that it wasn't even discovered until 2011. After a friend of mine showed me a picture of this beautiful nebula, I was hooked and I knew that I just had to image it. I spent many clear nights between Sep 16 and 21, 2022 trying to get data on this object. In total, I managed to get about 30 hours of data. This was my last serious target for this summer/fall before the weather got too cold and cloudy to image near the mountains where I live. I used NINA for collecting the data and the processing was done in Pixinsight. I used WBPP to calibrate, align, and stack the data. I then cropped and used DBE on the narrowband data. I used Linear Fit to match the background between channels, EzDenoise to denoise the data, and StarNet2 to do star removal and contrast enhancement using Curves before combining the narrorband data. I combined the RGB data for the stars and after further denoising and colour correction using the PhotometricColorCalibration tool, I stretched the stars and combined them with the narrowband data using PixelMath. I made final adjustments using the Curves tool in Pixinsight with several iterations of masks. -Your submission image quantities I am submitting 3 images in the Deep Sky category.
