M51 The Whirlpool Galaxy

I finally got my autoguider in focus, and turned to M51. I was never able to guide on this object with the LX600, but now that I'm automating it, the little StellarVue guide scope has no trouble locking.

This is a first light image from my latest (v3) filterwheel. I switched from MacOS to Linux and I haven't figured out the processing yet. The program I'm using doesn't seem to have a "make this black" function, or a "make this white" function, so the background is odd colored.
