Description

By cropping my subs, I was able to incorporate more frames and get a less grainy image of M51. Wish I had a longer focal length for this object... but this resolution is probably all the seeing would have allowed anyhow.

Didn't do any artistic manipulation of the colors on this. It's surprisingly blue.

Better decisions with noise reduction.
