The universe is like a safe to which there is a combination, but the combination is locked up in the safe.

By constellation:



NGC 637 (Open cluster)
Right ascension: 1h 44m Declination: 64° 6'
Constellation: Cassiopeia
Date/time: 2012.11.03 19:45 UT
Equipment: 4.5" f/8 Newtonian
FoV: 21' Magnification and filter(s): 180x
Seeing: 8/10 Transparency: 2/5
SQM: 20.06 m/as2 Temperature: 13°C
Humidity: low Wind: none
Sight: 2 - minor details, somewhat interesting
Difficulty: 2 - easily visible, some dark adaptation needed, averted vision might add to details
Position: 2 - easy, bright star nearby
Location: Lipótfa, Zselic, Hungary
Observer: Ferenc Lovró
Description:

Tiny little open cluster, compact but sparsely populated. I assume that only 8 of the stars in the FoV are the members of this OC. The full moonjust below my horizon is quickly ruining the sky background, worth taking a look under more favorable conditions, because I suspect that what I see is only a minor part of what I could really observe with this scope.
