Season 2012 M33
I struggled a bit with some wierd gradients in this image, I think I might go back to Deep Sky Stacker to do the initial stack, rather than using Pixinsight. Processing, by the way was almost totally done in Pixinsight, with the exception of a couple of little cosmetic tweaks and resizing for the web, these being done in Photoshop.
M33, this is one of the ‘Local Group’ of galaxies surrounding out own Milky Way, and estimates put it around 3 million light years from us, so it’s a little further than Andromeda. It is around 5,000 light years wide and has quite a few Ha regions (the red blothches) which are areas where new stars are being formed.
It is very faint but is supposedly naked eye from a dark site, although I have been to the Kielder star party and have never managed to even see a hint of it! If you fancy hunting it down with a scope the finder chart below should help, it’s pretty close to Andromeda, so if you cant find it, just swing across and have a look at M31 instead!
