Here's an image of the Western portion of the Veil Nebula. I took this image over several nights last week - there is a total exposure time of 24 hours that went in to this one (8 hours each in H-alpha, OIII, and SII, using 10 minute subframes). I'm trying to determine whether extended exposure times will improve the signal-to-noise ratio enough to overcome some of the limitations I experience when imaging from my back yard.
I've shot this one a few times before with the 105mm refractor; this time I used the Takahashi Epsilon 180ED astrograph. It does seem that I picked up some extra faint wisps of nebulosity in the field. In fact this field has so much H-alpha emission that there's a slightly reddish tinge throughout the field. The OIII really has some stunning features as well.
