When to photograph NGC 6752
NGC 6752 is a globular cluster in Pavo, 13′ across at magnitude 6.3. Also listed as C 93.
When to photograph it
From 45° N it never rises.
From 35° S the best months are June and July, with up to 11.0 hours of astronomical darkness above 30° in July. It reaches 65° at its highest. It never sets from this latitude, so some imaging is possible all year.
Framing
Its long axis is 13′. It fills 35 to 80% of the short side of an APS-C sensor at about 1420 to 3250 mm, and of a full-frame sensor at about 2190 to 5000 mm.
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 6752's altitude through tonight, its transit time and its distance from the moon. For sub length, use the exposure calculator.
