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.

ASI290MM first guiding job

I guess the picture below says it all !! RMS values of 0.30″ and 0.26″. The mount was setup in the garden that same night, using PoleMaster to align (one 7-minute session). The PHD2 Guidelog mentions a pole error of 0,5′ I guess that is 30″. Not bad for spending 7 minutes on aligning. Works like a charm.

This is no doubt rather good guiding. I’m happy with this result: a good combination of the ASI290MM smaller pixels and the old Soligor “free” 400mm F 6.3 DSLR telelens (I got it as a gift from a neighbour who found it on a flee market).
