Many people don't believe in God, do believe in the eventual heat death of the universe, yet despite that they continue to live and act as if their lives actually meant something.

By constellation:



NGC 7332 + NGC 7339 (Galaxy)
Right ascension: 22h 37m Declination: 23° 48'
Constellation: Pegasus
Date/time: 2008.10.01 23:45 UT
Equipment: 12" f/5 Newtonian
FoV: 18' Magnification and filter(s): 250x
Seeing: 6/10 Transparency: 4/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Two spectacular galaxies of similar size but different look, in a nice pattern, about perpendicular to eachother. NGC 7332 is a bit larger and much brighter, however visually I've seen it slightly smaller than its fainter companion. A reason for this might be its starlike, bright core, that is washing away the dimmer areas, and to which I estimate a brightness of about 12.7m. The galaxy is losing brightness smoothly toward its outer boundaries. NGC 7339 however does not have a starlike core, its surface looks perfectly homogeneous, it's has a shape of a cigar: faint and highly elongated. It has sharp edges. I estimate a surface brightness of 13.2m. Their sizes are: 0.5' x 1.5' for NGC 7332, which is much smaller than what is stated in the catalogue (1.1' x 4.1'!), and 0.5' x 2.3' for NGC 7339. The photos I've seen make me certain that I'm right by the size estimation, because on these the galaxy pair looks quite the same by size.
