There are 10^11 stars in the galaxy. That used to be a huge number. But it's only a hundred billion. It's less than the national deficit! We used to call them astronomical numbers. Now we should call them economical numbers.

NGC 6802 (Open cluster)
Right ascension: 19h 31m Declination: 20° 18'
Constellation: Vulpecula
Date/time: 2012.06.16 0:35 UT
Equipment: 12" f/5 Newtonian
FoV: 22' Magnification and filter(s): 167x
Seeing: 6/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

In the neighborhood of the famous Coathanger asterism lies this rather small, asymmetrical, faint open cluster. It's very spectacular thanks to its mysterious silver glow. About 8 to 10 cluster members are visible with direct vision, however plenty of stars are on the edge of visibility when looking with averted vision. These and the invisible companions are responsible for the shiny background glow that is elongated in the N-S direction and sometimes looking very elliptical. Despite it being very faint - or perhaps that is the reason - it is a very remarkable cluster.

SQM reading: 21.27 MPSAS, 11°C, humid.
