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.

NGC 6210 (Planetary nebula)
Also known as: Turtle nebula
Right ascension: 16h 44m Declination: 23° 48'
Constellation: Hercules
Date/time: 2008.06.22 21:00 UT
Equipment: 12" f/5 Newtonian
FoV: 15' Magnification and filter(s): 250x
Seeing: 4/10 Transparency: 4/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

An unexpectedly bright, but tiny (20") planetary nebula. If we already know what and where must we look for, it is an easy target. However, for me it was a really tough one for the first time: it took some time to realize that the mysterious "star" that shouldn't be there according to the star maps is in fact the planetary itself. At 71x it is completely star-like, however at 250x we are able to catch its smaller details too. It has an almond shape, elongated to the E-W directions, with a bright white core. Also towards these directions I could discover two faint little horns. It requires high magnification, and good seeing.
