Dear all, I agree with Taichi. At the first look the object look like a flaw but it appear in two images. In my page http://toniscarmato.interfree.it/novacyg2003.html I have added the second image taken at 5 minutes of interval. The object is visible more clearly. Unfortunately the focal length is low and the star is not well separated from the faint star visible in DSS images at the bottom of the arrow. My Megastar in the area show only a star GSC3159:240 mv=13.7. If this night the sky will be clear I will try to taken the field with the 25 cm Newton Telescope.
