I took some more shots of Arcturus last night. So far, last night was the clearest I've ever seen the night sky, not a cloud in sight.

Setting up is getting a bit easier, the worst problem is getting the speed correct on the single axis drive, once I'm polar aligned.

In April, I took a shot, but wasn't sure about stacking, so there was a lot of light pollution.

I stacked and cleaned up last nights shot using deep sky stacker and some darks and flats I took at the same time.

I'm pretty pleased with the result.
