An intermediate NGC3628

This galaxy is the third member of the Leo triplet. During the last nights I could image this with the Esprit120mm and the ASI183MM Pro. This intermediate result is L-filter 6hr36m of data processed in APP and cropped. Best seen by clicking on the image!

And below is the equivalent image taken with the Nikon D750 DSLR. I had a lot of noise in this 3hrs picture (36x300s), I suspect something went wrong with the dithering. The tidal stream is just visible.

And this was the guiding performance of the EQ8 during the last shot: sub-0.5″ accuracy! very happy with this. And indeed – there was no dithering going on. Need to look at that tonight.
