Messier 41 is an open cluster in the constellation Canis Major. It lies just south of the brightest start in the sky, Sirius. It is visible to the naked eye with dark skies and was "discovered" back in 1654, but there are indications that it may have been seen as far back as 325BC, as described by Aristotle. The cluster is around 215 million years old and is 2,300 light year from Earth.
Here are the technical details for those handful who might be interested:
Scope: Starblast 4.5; tracking on, but clearly not perfectly polar aligned
Magnification: ~30x
Camera: iPhone6 using NightCapPro app; ISO 8000(?)
Processing: 10 sec. image adjusted curves using GIMP
