Astronomy is the science of the harmony of infinite expanse.

By constellation:

NGC 7026 (Planetary nebula)
Also known as: The Cheeseburger nebula
Right ascension: 21h 5m Declination: 47 39'
Constellation: Cygnus
Date/time: 2008.09.03 00:00 UT
Equipment: 12" f/5 Newtonian
FoV: 16' Magnification and filter(s): 250x
Seeing: 6/10 Transparency: 4/5
Location: Ndasdladny, Hungary
Observer: Ferenc Lovr

I find this object much smaller (around 0.3x0.4') than what is suggested by the values in catalogues (0.8x0.8'). It's a fairly blue, very bright planetary with a shape resembles a diamond, divided in N-S direction by a dark belt of matter in the middle. Its name is very felicitous when taking a look at its entire shape: Cheeseburger nebula. I can detect an additional faint nub on the NW part of the object. Requires large magnification and a very calm atmosphere.
