Adjusting and some test photos

About a week ago was a clear night but both the seeing and transparency weren't that good, about 4 and 3. There were again some haze and ice crystals and the average FWHD was about 3.5.

Everything is working again and I spend about an hour to finalize my collimation. I got it pretty good, but I think I'll try to get it a little better... Less than 2" would be perfect. (Don't mind about huge gradients in the backgroud...)

And here's crop of two hours (12*600sec) exposure of NGC2805.

Due the bad conditions there's not so much of details. But I'm surprised how deep the image is!!
Here's some galaxies pointed out with Aladin sky atlas and NED (NASA/IPAC extragalactic database).
