When to photograph NGC 7000 (North America Nebula)
NGC 7000, the North America Nebula, is an emission nebula in Cygnus, 120′ x 100′ across at magnitude 4. Also listed as C 20.
When to photograph it
From 45° N the best months are August to October, with up to 7.3 hours of astronomical darkness above 30° in September. It reaches 90° at its highest.
From 35° S it never climbs above 30°. It peaks at 10° when it crosses the meridian, low enough that haze and light pollution soften it. It is possible with a clear northern horizon, but hard.
Framing
Its long axis is 120′. It fills 35 to 80% of the short side of an APS-C sensor at about 160 to 360 mm, and of a full-frame sensor at about 240 to 550 mm.
Filters and the moon
It glows in H-alpha, and often OIII, so a dual-band filter on a color camera or narrowband filters on a mono camera cut light pollution and keep it workable with the moon up. The dark sky calendar shows which nights this month are moon-free where you are.
Plan it for tonight
Dates and times depend on your exact location. The imaging planner shows NGC 7000's altitude through tonight, its transit time and its distance from the moon. For sub length, use the exposure calculator.

Gear that suits NGC 7000
NGC 7000 is 120′ along its long axis. These frame it on an APS-C sensor with room to crop. It shines in H-alpha and OIII, so a dual-band filter on a color camera cuts through light pollution and moonlight.
