Description

Data acquired in two moonless nights, with half of the L and all of the R, G and B frames on the second night, when the most of the streetligths in my neighborhood were off (though it didn't help that much as most of the LP comes from the nearby city to the north).

Sadly, on the first night dithering on DEC axis was disabled, so the noise of the background is very ununiform, even with added data with full dithering from the second night. So I had to use quite heavy noise reduction and slightly less stretching.

Also the guiding graph was far from perfect with Total RMS of about 1.5-2" most of the time. I think this may be caused by weak one ring mounting design of the scope, somewhat unsuitable for using with 60mm guiding scope on top.
