Grant93 Posted January 16, 2022 Share Posted January 16, 2022 Hello everyone! Had a nice week yet again last week, these clear skies for the UK recently are astonoshing! Usually I can get 3-4 nights per month of imaging, not per week! But there was a bright half moon night after night so I decided to point the scope north, on some relatively bright galaxys, M81 and M82. This is my first fully non-manually dithered image. Wow does dithering make a huge difference, very clear of a lot of noise, and the added bonus of not having to use darks! The only trouble I had with this, was there was dust bunnys that appeared on the picture. I used flats, but didnt take them until the morning before processing, so I wondered if the dust bunnys just moved, because they certainly worked to get rid of any gradients from vignetting. 7 hours of data, 2min subs 40 Flats 40 Bias Manually stacked in Siril ZS61 + 800D HEQ5 ASI224mc + AstroEssentials 50mm guidescope Astroberry to control the camera and guiding. Randomly Dithered 10 pixels every 3 frames Let me know what you think 7 Link to comment Share on other sites More sharing options...
