Clusters of clusters count, Glen? Here's why I ask:
* Table of Scorpius - some four or five clusters in the same line of sight. One very bright cluster, NGC 6231, being mainly OB stars, then other clusters, some larger in size but fainter members, another cluster huge in member stars, plus bright and dark nebulosity. Stunning rich, wide field.
* M7 - spectacular large cluster with three other OC's, a GC and some four PN's all within its boundary. A rich field scope or binos will show an intricate network of dark nebulosity. I use the tiny GC as a gauge for seeing conditions & transperancy if I can resolve some of its stars.
* The Jewel Box. Colour, bright stars & dim, takes magnification very well. Beautiful.
* NGC 6520 and B86. Located in the guts of Sagittarius, in a large aperture scope, the background is ablaze with the Milky Way, 6520 is a lovely pile of diamonds over the top of the MW. But what really sets it of is the Ink Spot dark nebula, B86. The whole scene is stunning.

How about the ones in Norma-Ngc 6067 etc. Ic 2391 in vela, Ngc 2516 Carina, and the Gem cluster. Ngc 6231 a cracker.
M37,M35,M11 the Wild Duck. These are just a few you could add to an enjoyable list.
Cheers Bigjoe.

How about NGC3532 and it's dark lane, M46 and the planetary NGC2438, N3114,M23 and as mentioned, the region around N6231,Tr-24,N6242.
These are some of my favourites.

M41. Not particularly amazing, but it has sentimental value for me since it was the first cataloged object I found with my first scope. its located just to the south of Sirius.

NGC 6231 in Scorpius.
Gem Cluster (NGC 3293).
Pearl Cluster (NGC 3766).
Tau CMa Cluster (NGC 2362).
Jewel Box (NGC 4755).
Most of the compact ones are pretty.

M45 - The Pleiades. First cluster I ever saw, knowingly from somewhere decently dark you can make out a number of the stars with the naked eye, but binoculars are a treat.
NGC 869/884 - The Double Cluster. Not visible from Sydney's latitude but further north?

I'd almost forgotten about that - Caroline's Rose is a beautiful cluster, better with aperture
The Owl cluster nearby is fun cluster too.

Those listed may be your favorites. But the best one by far is M73. Just, no comparison. Yep!
That being said I mirror Rob's sentiment that compact open clusters tend to be the prettiest.
M73 is the best tho.

Hi Glen,
As you probably know, M73 is not a "true" gravitationally bound open cluster. It is a chance line of sight alignment of unrelated stars. For decades there was discussion and debate on whether or not M73 was in fact a true open cluster. There was a paper released about 2000 which indicated it was an "old" open cluster whose stars were widely dispersed. The truth was established in 2002 when the distances to the 5 brightest members was calculated and it was established they were just too widely distanced to have ever been related. Of course in Messier's day everything was based on optical perception.
Cheers,
John B
