Reprocessed after astrobin crash - only AA7 - stack, crop, star shrinking, gradient correction, blur, histogram stretch.

Thanks for looking

This image has been taken on the 15.04.15 from my home terrace. Equipment used were a Vixen GPD2, a GSO RC8 and an Atik 383l+ mono in a bin 2 mode. A 35nm H-Alpha Baader filter was used as well. I had some troubles with guiding, so I decided to go to the unguided route - as extreme test I lunched 124 180 secs unguided subs. Never tried this at such focal length.
