When the Sun shrinks to a dull red dwarf, it will not be dying. It will just be starting to live and everything that has gone before will merely be a prelude to its real history.
/ Arthur C. Clarke /

NGC 457 (Open cluster)
Also known as: Owl cluster
Right ascension: 1h 19m Declination: 58° 17'
Constellation: Cassiopeia
Date/time: 2008.01.31 19:45 UT
Equipment: 12" f/5 Newtonian
FoV: 31' Magnification and filter(s): 71x
Seeing: 7/10 Transparency: 4/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

A sparsely populated open cluster that is limited by Phi Cas from the east. Prevailed by nearly a dozen stars of mag 10-11 with nearly identical colour and luminosity. In the background of these are fainter, nearly 13 mag stars of at least double the amount, which clearly form a cluster with their brighter companions despite the big difference in brightness.
