First supernova for me.
| Object ID | SN 2018 ivc in M77 Type II supernova |
| Details | 2018-12-03 22:10 – 22:39 UT |
| Telescope | 250mm f4.8 Newtonian, MPCC, IDAS P1 |
| Camera | Atik 460EX at -20C |
| Exposure(s) | L 10x90s 1×1 |
| Capture | APT |
| Processing | Nebulosity, Photoshop |
Lots of gradients and stray light from somewhere coming in. Hard to process and as a result have lost the fainter outer arms.

Terrible trouble with LP, noise and flats. Hard to process out the flaws.
Messier 81 (also known as NGC 3031 or Bode’s Galaxy) is a spiral galaxy about 12 million light-years away in the constellation Ursa Major. Due to its proximity to Earth, large size and active galactic nucleus (which harbors a 70 million M☉ supermassive black hole), Messier 81 has been studied extensively by professional astronomers. The galaxy’s large size and relatively high brightness also make it a popular target for amateur astronomers.
Messier 81 was first discovered by Johann Elert Bode on December 31, 1774. Consequently, the galaxy is sometimes referred to as “Bode’s Galaxy”. In 1779, Pierre Méchain and Charles Messier reidentified Bode’s object, which was subsequently listed in the Messier Catalogue.

Doesn’t really look like a globular – in fact it wasn’t classified as one for a while.
