Astronomy's much more fun when you're not an astronomer.

My astronomy sketches. Hover mouse over image for the inverted look. For fainter objects, take a look at the black-on-white original, sometimes it reveals more details.

NGC 4013 (Galaxy)
Right ascension: 11h 59m Declination: 43° 53'
Constellation: Ursa Major
Date/time: 2011.05.02 21:45 UT
Equipment: 12" f/5 Newtonian
FoV: 30' Magnification and filter(s): 100x
Seeing: 4/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

A tiny edge-on galaxy with a fake offcentre star-like core. It's fake, because it is actually a foreground star located in our own galaxy, that looks exactly in that direction. I was very surprised when I first noticed that this galaxy has its core out of its geometrical centre, but later studies revealed the answer for this phenomenon. This little gem is located in a very sparse stellar environment which makes it an extremely difficult target. SQM reading: 21.23m/arcsec2, 5°C, very humid.
