By constellation:



M48 (Open cluster)
Also known as: NGC 2548
Right ascension: 8h 14m Declination: -5° 47'
Constellation: Hydra
Date/time: 2010.02.21 20:30 UT
Equipment: 12" f/5 Newtonian
FoV: 47' Magnification and filter(s): 45x
Seeing: 7/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

This large, moderately bright open cluster can be detected easily in a 50mm finderscope or binocular. When looking through the telescope I see countless number of stars that are very similar both in colour and luminosity. I can also detect some foggy background which may be miriads of unresolved stars. The conditions were not perfect to sketch this cluster because the 50% Moon caused a low NELM (SQM reading was 17.33 towards the Moon and 19.46 opposite the Moon, -3°C, low humidity).
