Notes:

This image replaces a red-filtered 300 minute sequence from 2007.

Wanted to re-image this globular cluster with a longer total time ... but not quite this long! The first two nights had bad (~4-5 arc sec) seeing, the third night was good, the fourth night had a lot of high clouds, and the last night was OK ... so I used 116 of the subs to get a smoother, more natural image than my 2007 attempt, which was over processed.

Contemporary Visual Observation(s) for NGC 2419

NGC 2419 = Intergalactic Wanderer
07 38 08.5 +38 52 55
V = 10.3;  Size 4.7

17.5": fairly faint, round, 2' diameter, gradually brighter core but no well-
defined nucleus, mottled appearance although no resolution into stars.  Framed 
by a quadrilateral of four mag 13-14 stars and a few other faint stars.  
Collinear with mag 7.0 SAO 60232 4' W and mag 7.9 SAO 60229 8' W.  This globular 
is dubbed the "Intergalactic Tramp" and is one of most distant globulars from 
earth.

8": very faint, small, round, no resolution.  Collinear with two mag 8 stars to 
the W and a mag 9 star in the field W.
