I spent the wkend camping in a dark site, nelm est 5.5-6, and had scope along. While I was exhausted after a very active day, I was at least 1.5 hrs fully dark adapted. N Amer and Veil were distinct in scope and binocs without filters. PNs 6781 & 6852 were nice and fairly easy too. I'd never looked but saw it in PSA and tried for it. It was a VERY rich star field and I never did find it. I vaguely remembered it was larger and was using the 13mm (92X- .7 deg fov) with and without the NPB filter. I'm looking for some hints I guess. Did I just overlook it or is it very faint and requiring more time/effort? Steve
Based on your seeing the Veil and NAN without filters, I suspect you should be able to observe the Crescent without much difficulty when using an NPB or similar filter. Perhaps it was just your being tired. What is a PSA?
Here is my observation of the Crescent from last week, bigger scope, darker site:
N6888 Cyg BN 18.0'x8.0' 20 12 01 38 23 00 8/1/08 174X NPB, Sh2-105, Crescent Nebula. Located almost a third the distance along a line from Gamma to Eta Cygni. The views of this object each year at Lassen replace the past ones as "the best" and this year was no exception. The fine wisps of nebulousity interior to the egg shaped shell, especially inside the thick bottom band, was amazing. Detail could be picked out all the way across from one side, through the Wolf-Rayet progenitor star, to the other side of the shell. This is a great object at Lassen, where it is in the same class as the Veil Nebula for visual beauty.
Clear skies,
