Astronomy teaches the correct use of the sun and the planets.

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:



M46 (Open cluster)
Right ascension: 7h 42m Declination: -1° 51'
Constellation: Puppis
Date/time: 2013.03.02 20:00 UT
Equipment: 4.5" f/8 Newtonian
FoV: 1° 2' Magnification and filter(s): 60x
Seeing: 6/10 Transparency: 4/5
SQM: 21.36 m/as2 Temperature: -8°C
Humidity: low Wind: none
Sight: 3 - definite details, interesting look
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: Lipótfa, Zselic, Hungary
Observer: Ferenc Lovró
Description:

This open cluster is made of plenty of faint stars. Many visible with direct vision, but the majority of even fainter stars are visible only with averted vision. It separates well from its background, but it's definitely not an easy object just next to the much brighter M47.
