Last night was finally clear! I took my previous picture at March 15., after that, there was no astronomical darkness to work with, since I live at 65N. My first target was the "Propeller Nebula" in constellation Cygnus.
About six months mandatory pause makes no good ones skills and routines. Last night I forget to plug in a power cord of the filter wheel, stupid me. I thought, that I was shooting H-alpha channel, instead I shot four hours of very weak O-III signal. That's OK, I can use it later for a color image, but due my mistake I have nothing to show here, there is very little to see in ionized Oxygen band . (Mainly stars, noise and some very dim signal from the ionization)
Since I don't have anything to show in this post, please, have a visit in my portfolio, there is some re organization done lately: http://astroanarchy.zenfolio.com/
