Preparations for fall

05:18 26/7/2009 UTC

Brightest constellations are already visible after midnight, so it is time to begin preparations for the next season. My goal was to get the system dither between exposures and to try out Nebulosity2 with CCD. After some struggle with guiding, I got everything to work. I just received two of the three new narrowband filters, so I had to try a traditional fall object M27 with it. I did three 600s OIII exposures. Altough the sky is still bright, very dim outer parts of the nebula is starting to come out. This is 100% crop from the center of the frame.
