When to photograph IC 1613
IC 1613 is a galaxy in Cetus, 18′ x 17′ across at magnitude 9.5. Also listed as C 51.
When to photograph it
From 45° N the best months are September to November, with up to 6.3 hours of astronomical darkness above 30° in October. It reaches 47° at its highest.
From 35° S the best months are September and October, with up to 6.7 hours of astronomical darkness above 30° in October. It reaches 53° at its highest.
Framing
Its long axis is 18′. It fills 35 to 80% of the short side of an APS-C sensor at about 1030 to 2340 mm, and of a full-frame sensor at about 1580 to 3610 mm.
Filters and the moon
Galaxies are broadband targets. Filters cannot separate their light from light pollution, so dark skies and moon-free nights matter most. The dark sky calendar shows which nights this month are moon-free where you are.
