NGC 7380 The Wizard Nebula (Sh2-142) in Hydrogen Alpha

Finally the skies cleared last night to allow a bit of astrophotography. Still learning the foibles of my own homemade GEM mount, but hopefully we are starting to get somewhere. This is 9 x 1200s exposures combined and stretched a bit. Art 285 camera with Astrodon 6nm Ha filter on a F5 8 inch newtonian. The full resolution version has an image scale of around 1.33 arc seconds per pixel.
NGC 7380 is the open cluster of stars discovered by Willian Herschel's little sister Caroline in 1787. Of course, they wouldn't have spotted much of the nebulosity in the region - the is is catalogued in the Sharpless catalgoue as sh-142.
The major problem with the data is the horrific star shapes. Although the scope is guiding ok in RA, the DEC guiding is still rubberbanding all over the place. More work required.
