Here is the combined list of clusters, nebulae and galaxies.

1. OC

These are the 50 brightest Open Clusters in order.
They range from magnitude 1.6 to 5.7.
Only M, NGC and IC objects are listed.
Some interesting nearby objects have also been included.
To pick the best OCs look at them with a telescope or use software that shows stars to mag 14+

Glen,

Me thinks the crappy weather we're having up here in paradise, is leaving
you no observing time.

btw, looks to be another outstanding list of objects to keep one going for
some time. I'm still working on your 111 non messier list. Which I have
barely touched due to low flying nebula

regards,CS sunny days

Another nice link Glen. I'm wondering if anyone has gone to the effort of memorizing one of these 3D views of our distant neighbors?

[GrahamL]

ngc 2070 is one of my favourites .. might be more the LMC I like but its one I always seem to go back to :)

another great list glen many thanks .

[glenc]

I have added NGC 346 & 2070.
