Mount upgrades complete, back to M51

[Tzetze]

So, I replaced the standard cog/gear drive mechanism in the EQ6 with a belt mod and replaced all the bearings while I was at it. It took quite a while to get things tuned back in following the rebuild but all seems well tuned now if last night's subs were anything to go by (guiding error of .58"-.75" RMS).

I went straight back to M51 to complete some unfinished business.  Here's 15x 600s sub-frames to give a total 2.5hrs integration time (click image for full res version).

That's a very good M51 and only 2.5 hrs.

Thanks Richard. I wasn't happy with the black point in the image above so I pulled down the black point a bit and boosted the saturation some more. I think I prefer this second version.
