M83 in mono

Tried out the all star polar align routine on my CG-5 last night and captured this afterwards. I have to say, considering how long it took to align using that method, I'm pretty damned happy. I think I'll use a variant of it going forward rather than drift aligning. I did have a significant number of throw-aways, roughly 50%, but I think I can fine tune that and again, effort:reward ratio was high.

I took about 30 more 120s subs but fog rolled in and killed those.

Capture details:

22x90s, -13c, 100 sub bias, 100 sub dark
4x120s, -13c, 100 sub bias
Mount: Celestron CG-5GT
OTA: Skywatcher BD ED80

And for the sake of comparison, here is the best I was able to do with a dSLR and 30 second exposures... 101 frames with a stupid amount of noise reduction:
