Astronomy is one of the sublimest fields of human investigation. The mind that grasps its facts and principles receives something of the enlargement and grandeur belonging to the science itself. It is a quickener of devotion.
/ Horace Mann /



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

Seeing: 7/10 Transparency: 2/5
SQM: 17.95 m/as2 Temperature: 6°C
Humidity: moderate Wind: gusts
Sight: 4 - lots of details, very interesting, unique look
Difficulty: 3 - moderately visible, dark adaptation needed, averted vision might add to details
Position: 1 - very easy, many bright stars nearby
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Faint, large open cluster with member stars of very similar brightness. Sparsely populated, yet it features many spectacular stellar paths. A really nice object, should make a great target on a better evening. In the Eastern corner of the FoV I can see a really nice, perfectly square pattern of stars. The Half Moon is near the Auriga constellation, and sometimes stormy wind gusts make observation harder.
