We live in a changing universe, and few things are changing faster than our conception of it.

By constellation:



NGC 6503 (Galaxy)
Right ascension: 17h 49m Declination: 70° 08'
Constellation: Draco
Date/time: 2009.07.25 22:00 UT
Equipment: 12" f/5 Newtonian
FoV: 26' Magnification and filter(s): 167x
Seeing: 5/10 Transparency: 5/5
Location: Jászszentlászló, Hungary
Observer: Ferenc Lovró
Description:

Bright, small galaxy near a very yellowish star, which I captured on a surprisingly cold night that offered an excellent transparency in the early evening hours near the village of Jászszentlászló, Hungary during the Kiskun Astro Camp. Its shape is not perfectly cigar shaped, but its northwestern end looks a bit truncated. Its surface is not entirely homogeneous: next to its gradually brightened yet not star-like core it shows many little details, changes in luminosity of its surface. SQM reading: 21.24 m/arcsec^2, 12°C. The faintest field star visible directly is about 15.1 magnitudes bright, the NELM was 6.5 at this time of the evening.
