15cm f/5 Primero

Very large, visible to the unaided eye as a faint glow east of Deneb, in Primero it is easily locate and quite distinct even without a filter, of course a 3° field at only 22x helps a bit, the southern edge (LDN934, the Gulf of Mexico) is quite distinct and the void between NGC7000 and IC5070 is much darker than the surrounding glow, with a UHC filter the nebula is somewhat more obvious, certainly the darker voids more pronounced, the northern edge fades very slowly into the Milky Way background.

Great nebula found by Wolf on photos; sharply defined s, and containing a dark opening like a cross. Visible as a glow in a field glass, but brightest part scarcely visible in 17-1/4 in. reflector. Es.
