Bubble 9/12/2015

Lee collimated the scope last Saturday and this is the first image I've made since then. What an improvement! There is only a small ghost now but that may be down to focus ( the electric focuser stopped working so I had to do it manually). Collimation is much better because the star count on this image is "through the roof". I normally get a count of 200 to 400 stars in Deep Sky Stacker, but this one came in at 26600 !!!

This is NGC7635 or the Bubble Nebula.
