By a Nose

My final image of the Horsehead Nebula (IC434, B33) for the year. I was hoping to add another couple of hours worth of subs, but it was not to be as the last set of images were taken after the camera had been removed and reinstalled. I’ve never been able to get the camera to align along the same plane as before when reinstalling the camera. This error causes the images to fail to align correctly, and is part of my problem with stars in the images appearing slightly elliptical in shape.
