Veil Nebula

There are three main components of the Veil Nebula. The western veil (center bottom of image), the eastern veil (top, just right of center), and Pickering's Triangle (large nebula between the other two), which was discovered by Williamina Fleming, but credit was given to her observatory directory, Edward C Pickering. The source of the nebula was a Supernova explosion of a star 20 times as massive as our own Sun. Estimates are that the star exploded 10,000 to 20,000 years ago. The supernova, had we seen it, would have been brighter to us than Venus. Estimated distance to this nebula is 2,400 light years. The whole nebula is approx 65 light years across and from our perspective, if compared in size to the moon, would be 6 times wider/taller. Image was captured over 3 nights in Sep/Oct 2023 using a small 51mm refractor telescope.
