Christmas Tree and Cone Nebula
I took this a couple of weeks ago and have been playing about with it in Pixinsight. Eventualy I dicovered that a couple of subs were no good – 1 had trailing (albeit slight) and the other must have had soem high cloud as it was very orange. So, I took them out and restacked and with a bit of messing here is the result – still not completly happy with it, but dont know what I want it to look like, never mind how to do it!
3hrs in 15min subs with Altair F4 Newt and QHY8, guided with WO70mm and Meade DSI. Processing done in Pixinsight, with a wee tweak in Photoshop.
As usual I went back and had another play, so I present 2 images below….
