NGC 281 - Apparently a very bright Ha target. Astrophotogallery.org Large/Moderate Object October, 2008 Runner-UpA combination of two sets of data - RGB taken with an ED80 and Ha taken with a 130/780 refractor. Registered in DeepSkyStacker, combined in Photoshop Elements by Starizona method 2 and then adding the RGB as a top layer (Lighten) at 70% opacity to add in stars.Then, because the hue was somewhat pink due to the addition of the Ha as luminance, I placed a "hue" layer consisting of the original RGB image at 100% opacity on top of this image to bring back the original red Ha color.I was pleased to see that I could actually combine data from two different focal length scopes - a year apart, at that.Canon 350D Hap Griffin Baader Mod21x360sec at iso 1600
