We owe our existence to stars, because they make the atoms of which we are formed. So if you are romantic you can say we are literally starstuff. If you're less romantic you can say we're the nuclear waste from the fuel that makes stars shine.
/ Sir Martin Rees /

Stock 23 (Open cluster)
Right ascension: 3h 12m Declination: 60° 0'
Constellation: Camelopardalis
Date/time: 2008.02.20 19:00 UT
Equipment: 12" f/5 Newtonian
FoV: 20' Magnification and filter(s): 71x
Seeing: 6/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

This is a large open cluster with a diametre of around 15'. Not that spectacular, although it can be clearly distinguished from its environs that is relatively poor in stars. It has two separate shiny parts, with the brightest stars as shiny as 7.5-9 magnitudes, sparkling in all different colours. The Western part of the cluster has an optical double at its end towards the middle of the cluster that can be easily separated, and where both members are also real doubles in themselves. However, I could not resolve those doubles at this magnification level.
