Just found a neat site called The Messier Objects.
http://astro.nineplanets.org/dssm/messier.html
I was surprised on scrolling through the list, however, that M45 -the Pleiades - is given an NGC number (1432). Now as a amateur astronomer of some years experience, I am pretty sure that M45 never was assigned as an NGC object. A little research elsewhere told me that NGC 1432 is the nebulosity associated with the Pleiades, which takes a large telescope to observe visually, which is certainly different to the large naked eye star cluster.
So I then scrolled up to M24, which I also remember being otherwise unassigned, only to see it listed also as NGC 6603, which I thought was an open cluster within the M24 star cloud.
A little thing, sure, but just a reminder that a not everything on the 'net is necessarily accurate.
Also, it was an excuse for me to get back on to the forum, as I haven't posted anything for more than a year:rolleyes:
Cheers
