How quickly do we grow accustomed to wonders. I am reminded of the Isaac Asimov story "Nightfall," about the planet where the stars were visible only once in a thousand years. So awesome was the sight that it drove men mad. We who can see the stars every night glance up casually at the cosmos and then quickly down again, searching for a Dairy Queen.

Also known as: White Eyed Pea
Right ascension: 16h 12m Declination: 12° 3'
Constellation: Hercules
Date/time: 2010.05.10 22:50 UT
Equipment: 12" f/5 Newtonian
FoV: 21' Magnification and filter(s): 167x
Seeing: 6/10 Transparency: 4/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

This extremely tiny planetary is located in a relatively heavy environment, it's not an easy find. At 71x you can perhaps suspect that it's something other than a simple star, I can hardly say that it has any extent. At 167x it looks like a little fuzzy star. At 300x the body of the planetary can be detected easily, as an object which is getting constantly brighter towards its centre. To the South a spectacular binary can be found the STF 2016 (a Struve double). The size of the planetary is about 0.5' and is perfectly round.
