Little disappointed on how this one came out for 14 hours of exposure ... I guess narrowband filtration is required to really show the filamentary structure. It may be that conditions lately were not the best. It has been mostly 'clear' here (occasional high and/or mid level clouds), but more humid than normal. We have been on the western edge of a large high centered over the four corner area for the past week or ten days, effecting this image and the Dolidze 27 and LBN 35 image.

Contemporary Visual Observation(s) for NGC 6960
NGC 6960 = Veil Nebula = LBN 191 20 45 58 +30 35.7 Size 70x6 13.1": this is the prominent western section of the "Veil nebula" and is spectacular with an OIII filter. Bright, extremely large, very elongated N-S, stretches across the entire low power field while passing through the bright unequal double 52 Cygni = 4.3/9.5 at 6". Fans out to the south and splits into two delicate branches and fainter wisps. The bright curving nebulosity N of 52 Cygni has a remarkable "electric" quality. It has an abrupt bend about midway and then tapers down to a narrow tip towards the north end gently bowing out towards the W side. Fantastic detail using a 20 Nagler and OIII filter. - by Steve GottliebHistorical Research Notes / Correction for NGC 6960
NGC 6960, NGC 6974, NGC 6979, NGC 6992, NGC 6995, and IC 1340 are all part of the Veil Nebula, the wonderful supernova remnant in Cygnus. The various parts are so large, and most of them so bright, that the generally poor positions in the NGC don't matter. Only the position for NGC 6974 (which see) is completely off its intended part of the nebulosity. WH describes his "front-view" (what we now call the Herschelian focus of a reflecting telescope) in a note to his observation of NGC 6960. He writes that at the Newtonian focus the nebula extended one degree across the sky, while at the Herschelian focus, it stretched twice as far. He is clearly extremely pleased with the performance of his telescope in its "front-view" configuration, but I expect that the additional awkwardness in using it drove him to the Newtonian focus for most of his sweeping. In the IC2 Notes for NGC 6992, Dreyer paraphrases a short note by Pickering (at the end of an article in ApJ 23, 257, 1906) which describes the appearance of the entire Veil as seen on a 24-inch Bruce plate of 4 hours exposure. Unfortunately, Pickering chose to not publish the photograph; it would have made an impressive plate in this early ApJ paper. - Dr. Harold G. Corwin, Jr.
