imaged NGC 5466 (Halifax)

BGO captured NGC 5466 for me. A globular cluster in Boötes near the Canes Venatici border. One of the RASC Finest NGCs. It's big! It has the initial appearance of an open cluster! A loose globular? But that glow from within... It must be close (52 000 ly). The nearly straight line of stars at the bottom-right is interesting.

Luminance only, 60 seconds subexposures, 10 stacked shots. FITS Liberator, Paint.NET. North is up; left is east.

There's an oval fuzzy near the right edge of the image, west of the glob. A distant canted spiral? SkyTools 3 Professional says that's MCG 5-33-43 aka PGC 50187. An SBb spiral with a light time of 0.5 Gyr.

I think I see a faint small fuzzy near the bottom-left (south-east of the globular), near a pair of faint stars, J140545.3+282514 and J140544.3+282506. ST3P identifies this as LEDA 1835025.

Ha. I wasn't sure as I examined the image closely but in fact there's a LEDA galaxy at the bottom-centre (south of 5466), in an L-shape with the stars GSC 02012-0595 and GSC 02012-0176. That's LEDA 1833246.

I didn't see it at first but it is pretty obvious. Above (north) of PGC 50187 is LEDA 1840778. A smaller oval patch. Very faint.
