The constellation of Cassiopeia is slowly creeping its way back to dominate the North skies in the Northern hemisphere, and it caught me by surprise. A little after midnight, I was awakened and as usual, I looked through the window. I expected to see another night of endless cloud cover, but I saw Cassiopeia rising in a crystal clear sky. I seized the opportunity to set up and pointed the telescope at the Pac-Man Nebula (NGC 281).

This region is an emission nebula located about 9,200 light years away from. I collected just over 3 hours of 5-minute frames. After processing, I thought I’d use this post as a progress check 🙂. See my first image of NGC 281 in 2020, my rendition in 2021, and the 2023 edition (in the featured cover image. What do you think 🤔 ? Until next time, remember to look up and experience an amazing Universe!
