I had a few hour window of clear weather the other night before cloud came over.

I am planning to do more on this one but I was surprised at how well "only" 3 hours of data turned out. I guess that is the big advantage of aperture - the light gathering power. I am used to requiring more like 10 hours to get this level of signal. This could be handy given the vagaries of clouds and weather.

Planewave CDK 17, FLI Proline 16803 at -39C, Astrodon Gen 11 LRGB filters,
Paramount ME mount. I am continuing to tweak polar alignment using TPoint and it must be pretty close now after several runs through that and drift aligning. TPoint is a cool program and can be used with any mount and camera.

I also suspect there is a largish star tidal stream going from that yellowish bottom galaxy back to the main spiral arms. Longer exposure may prove it to be there or not.
