Setting loose on the battlefield weapons that are able to learn may be one of the biggest mistakes mankind has ever made. It could also be one of the last.

By constellation:



NGC 2420 (Open cluster)
Right ascension: 7h 39m Declination: 21° 33'
Constellation: Gemini
Date/time: 2011.03.07 19:00 UT
Equipment: 12" f/5 Newtonian
FoV: 29' Magnification and filter(s): 100x
Seeing: 6/10 Transparency: 4/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Very spectacular, yet quite compact cluster that shows a diffuse background, that is bright enough to be visible in the 8x50 finderscope as a tiny hazy spot. The environment is rich in stars, but the cluster is clearly separated. I estimate a visible diameter of about 4', but the cluster is drop-shaped, not round. SQM reading: 21.16 m/arcsec2, -5°C, bit humid air.
