"3" Asterism
« on: 2013 May 01 02:10:41 »
Hi folks,

Greg Parker drew my attention to a "3" asterism (link) so I thought I'd have a crack at it. Just 5 x 200 seconds in each of R, G and B with the TEC 140 and the ML16803. The subs would benefit from going a little deeper but here's what I found (25% scale) at 09h 38m 15s, +15° 20' 46":

and here's a crop (50% scale)

BTW, I don't usually add diffraction spikes but for this one I made an exception!

Does anyone know if this object has a name?

Bob.

Hi Bob
Very interesting cluster! I can't give you any information on this one, but I have another interesting cluster for you: NGC2169, also known as the '37' cluster in Orion. This one is on my list for the next winter!
Are there other 'numbers' in the sky??? Maybe even PI ....  :o
