Part of my series of test-images which I took in my first year of astrophotography. I was learning everything at once, from getting to know an equatorial mount to fully automating a session. Doing all this in 1 year resulted in many headaches, but I enjoyed every minute of it. I'm uploading some of these just to see the progress I had during that time.

This is the first time my remote setup functioned without a hitch, after 6 months all hick-ups seem to have been solved. Yay! :) 4 nights of recording while I slept, 120x 5 min originally. However, after analysis in Pixinsight I noticed just 2/4 nights were transparant enough for the best S/N ratio. Difficult target this one, I probably lack some PI knowledge here to get those clouds out better. Let's keep on practicing!
