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.
To prepare for the clear nights to come, I made use of a brief clearance between clouds to test the polar alignement. I connected the ASI174 to the Esprit f=840mm and let PHD2 guide for 4 minutes. The Polar Alignement stabilized on 4 arc minutes
Is that good enough?
And the result of the next night: the PHD2 Guidelog analysed with PECPREP
