Rosette Nebula 


Caldwell 49, the Rosette Nebula

Lots of stuff went right, lots of stuff went wrong with my attempt at Caldwell 49, the Rosette Nebula. Second time I tried tracking and managed 3-minute subs but I have tons of fixed pattern noise, also known as walking noise, over the image.
My next attempt I will turn over camera control to the laptop through Astro Photography Tools and add dithering to the mix which will help mask that.
Better than I thought I would get  but not so good. Anyway at least I got an image.
