Description

About 6hrs worth of data over 2 nights from my backyard. First light with my replaced Rokinon 135mm. The original had issues with back focus and as I'm using a DSLR there isn't a lot I can do to fix it so I ended up deciding sending it back would be easiest. The new one is nice to have since it took a month to get it shipped back, however the issue still remains, and the corner stars are all elongated towards the center. 

Thankfully Blur Xterminator does an incredible job correcting these, and while not perfect, the results are good enough that as long as I stay away from pixel peeping I can hold out till I get a dedicated astro cam. 

Overall I'm fairly happy with how the image turned out, obviously having an unmodified camera restricts how much signal I was able to pull out of the nebula without making it too noisy but I feel that I was able to get more than enough for a decent image and I learned a couple new things in PI.

Here's to no more clouds for the next new moon coming up!
