Magnificent desolation.

In memoriam Halton C. Arp (1927-2013).


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.

By constellation:



NGC 6504 (Galaxy)
Right ascension: 17h 56m Declination: 33° 12'
Constellation: Hercules
Date/time: 2009.05.25 23:45 UT
Equipment: 12" f/5 Newtonian
FoV: 21' Magnification and filter(s): 167x
Seeing: 3/10 Transparency: 4/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

A very faint, tiny little GX with an apparent magnitude of about 13.6-13 magnitudes. Its core is popping out strongly from the galactic plane and resembles an almond, although the Northern side of the core looks brighter, therefore it seems to be asymmetric. It demands high magnification levels. At 250x the shapes were easier to see, unfortunately because of the terrible seeing I had to step back to a lower power. Photographically it looks quite the same as NGC 4762.
