Dave Shave-Wall writes: After managing to get 4 images in total last night before the clouds rolled in I now have a 40 min exposure image. I will of course go out and get some more, but for now I think this shows a huge difference in a single exposure of 10min verses a stacked image of 40min. I hope you like it.
Tim Powell writes: Another quick image from last night, M81 and M82. Two hours total exposure time, 5 minutes per exposure. If I can get a good night without the moon I'll have another go with longer exposures. Aligned and stacked in Iris, processed in Pixinsight as normal.
The Medusa Nebula is a very old and large planetary nebula in the constellation of Gemini on the Canis Minor border. It also known as Abell 21 and Sharpless 274. The Medusa was discovered in 1955, and until the early 1980s it was thought to be a supernova remnant.
