Great shot, Steve. The big blob is an overexposed shot of the star in that location. What you are seeing is your aperture, meaning the opening of your scope. That's my opinion anyway. Still a great shot.

Sky was dark and the moon setting. I was able to set up, I had no, none, nada issues with drivers, cables or Murphy (this is the first time he deserted me). I would like your opinions as to whether the big bright ball around the intense nebulosity area is an internal reflecton off my pollution filter. I do like my picture and I hope you do also. Horsehead Nebula see: http://home.comcast.net/~galico/Astropics/Horsehead.jpg I got 53X250 Second Images,ISO 1600 of which Deep Sky Stacker used 46 with a 85% setting for usable frames. There was a satellite that does show up in the images.
