This is the first Astrofest I've been to where Orion was rising early enough to get some subs before dawn. I managed to get a few Ha subs of B33. Unfortunately the clouds rolled in too early on Friday to finish this off however for my first attempt at the Horse I'm quite please with how it turned out.
18x5mins (90 mins) Ha using the SN10/QSI683.
