NGC6990 NGC6992 NGC 6995 NGC 6979 NGC 6974 Veil Nebula, Witch’s Broom Nebula, Pickering’s Triangular Wisp
Another image I took with 300mm lens some time ago. Nebulae in this photograph are so large that it would be very hard to image them through a high power telescope. You would have to stitch a lot of images together to get a whole picture. Even 300mm lens captured only part NGC6960 because I wanted to get NGC6992 in the picture too.

Brief: Veil Nebula is remnant of supernova explosion that occurred 5,000..8,000 years ago. It is located approximately 1,500 light years away from Earth. It contains hydrogen, oxygen and sulfur, making it an interesting target to image though narrow-band filters like Hubble Space telescope.
