When to photograph NGC 7006
NGC 7006 is a globular cluster in Delphinus, 4′ across at magnitude 10.5. Also listed as C 42.
When to photograph it
From 45° N the best months are August and September, with up to 6.2 hours of astronomical darkness above 30° in August. It reaches 61° at its highest.
From 35° S the best months are June to September, with up to 4.5 hours of astronomical darkness above 30° in June. It reaches 39° at its highest.
Framing
At 4′ it is small. Even 4000 mm of focal length leaves it filling less than a third of an APS-C frame, so it suits long focal lengths, small pixels and good seeing.
Filters and the moon
Clusters are broadband targets, but bright ones tolerate some moonlight and light pollution. Short subs keep the brightest stars from clipping. 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 7006's altitude through tonight, its transit time and its distance from the moon. For sub length, use the exposure calculator.

Gear that suits NGC 7006
NGC 7006 is only 4.2′ across, so it stays small in any amateur telescope. The longest focal length gives it the most pixels.
