Similarly, many a young man, hearing for the first time of the refraction of stellar light, has thought that doubt was cast on the whole of astronomy, whereas nothing is required but an easily effected and unimportant correction to put everything right again.

Description:

If I wouldn't check this object out previously with my planetarium-software, I would most probably didn't even notice this sparsely populated open cluster through the telescope. Catalogues claim that it has a diameter of around 25', however it looks larger to me. Its three brightest 7m members rule the field of vision. Unfortunately at the time of this sketch, the Moon was in a phase of around 35%, painting the entire sky gray, which is probably the reason why I haven't noticed any stars brighter than 13m in the area even by using averted vision, no matter that there were an excellent seeing this time.
