Cygnus Mosaic - Sadr Region This was my first attempt at a mosaic and I stumbled on to the fact that I could actually do it by accident. My setup isn't perfect for mosaics - full frame mirrorless camera has a lot of vignetting and unflat corners (leading to bad stars in the corners), but I really wanted to try it. Luckily, I got enough clear nights to get enough panels to make it happen. With 21 hours and 20 mins of total integration, this is officially my most time in one image. Each panel is roughly 4 hours worth of data with the Sadr Region panel having 6.5 hours and the panel right below the Tulip Nebula having 3 hours and 20 min. Processing was a real pain, due mostly to my imaging setup but also random light gradients from being in Bortle 8. It's not perfect by any means, but I am happy with the result (doesn't mean I won't be working on trying to make it better!) . 21 hours, 20 min integration Dark, flat, dark flat and bias calibration frames Bortle8 .
