God is infinite, so His universe must be too. Thus is the excellence of God magnified and the greatness of His kingdom made manifest; He is glorified not in one, but in countless suns; not in a single earth, a single world, but in a thousand thousand, I say in an infinity of worlds.
/ Giordano Bruno /

NGC 6223 (Galaxy)
Right ascension: 16h 43m Declination: 61° 35'
Constellation: Draco
Date/time: 2015.07.07 23:00 UT
Equipment: 12" f/5 Newtonian
FoV: 10' Magnification and filter(s): 250x
Seeing: 4/10 Transparency: 2/5
SQM: 19.72 m/as2 Temperature: 24°C
Humidity: high Wind: breeze
Sight: 1 - nothing spectacular
Difficulty: 4 - hardly visible, dark adaptation and very dark skies needed, averted vision is required to see details
Position: 3 - moderate, some starhopping needed
Location: Talpa Minor Observatory
Observer: Ferenc Lovró
Description:

Extremely faint, tiny galaxy, although I'm sure that with better sky conditions (the rising Moon lits the highly humid sky) it would be easier and more spectacular. It's slightly elongated to the WNW-ESE direction, but almost round by shape with a core only slightly brighter than the rest. At 71x power it only appears occasionally at 250x it clearly appears by direct vision at all times, but it's a definitely hard sight.
