From 45° N the best months are February to April, with up to 7.2 hours of astronomical darkness above 30° in March. It reaches 53° at its highest.
From 35° S the best months are March to May, with up to 5.8 hours of astronomical darkness above 30° in March. It reaches 47° at its highest.
Framing
Its long axis is 10′. It fills 35 to 80% of the short side of an APS-C sensor at about 1840 to 4210 mm, and of a full-frame sensor at about 2830 to 6470 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.
Plan it for tonight
Dates and times depend on your exact location. The imaging planner shows M 49's altitude through tonight, its transit time and its distance from the moon. For sub length, use the exposure calculator.
