Three galaxies in Cetus (the Whale). In the upper right is the M 77, a barred spiral galaxy about 47 million light-years away. We are viewing it face-on and its faint arms can just barely be made out. Centre-left is NGC 1055, an edge-on spiral galaxy estimated to be 52 million lights years distant. The central dust lane can be clearly distinguished. Finally, almost directly below M 77 you can discern a small faint smudge. That is the barred spiral galaxy NGC 1072, currently calculated to be an astonishing 369 million light years away. #clayhausphotography #explorescientific #zwo #asi533mcpro #asiairpro #astrophotography #astronomy https://www.instagram.com/p/CW8bPn2BYgz/?utm_medium=tumblr

NGC 7635, the Bubble Nebula, is an H II region emission nebula in the constellation Cassiopeia. This is a very faint object seen visually through a telescope but astrophotography clearly reveals the bubble. The “bubble” is created by stellar wind from a massive hot, young central star. The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow. This was captured mid last month from my backyard with my 102 mm refractor when we had a few days of respite from the wildfires’ smoke. It is about 4 1/2 hours of data. #explorescience #explorescientific102ed #asi533mcpro #zwocameras #optolong #optolonglenhance #asiairpro #astronomy #astrophotography #clayhausphotography https://www.instagram.com/p/CTcOTrjH4rY/?utm_medium=tumblr
