111 NGC objects
Thanks Mick.
Did you see the list of 111 Bright NGC objects under Projects & Articles?
That is distilled from the information below.

How bright are bright nebula?
We don't have magnitudes for bright nebula.
The best brightness values that I have seen are in the:
Visual Catalogue of Galactic Nebulae
by Andreas Alzner and Ronald Stoyan (alz & rcs in the files)
in the Webb Society Quarterly Journal, January 1996
They rank them as:
1=very bright (M 42, M 17)
2=bright, easy without filter (M 78, NGC 1491)
3=of medium brightness, mostly good use of filtration (NGC 2174, NGC 896)
4=faint (S 157, S 301)
5=very faint, definite (VMT 10, IC 2118)
6=very faint, only suspected (S 188, S 240)
e= details visible
The attached 2 files list some nebula in order from bright to faint.
The first file is from telescopes 120 to 200 mm in aperture, R = refractor, N = newtonian.
The second file is from 360 mm newtonians.
The files can be copied into MS Excel.

Glen,
Could I have your permission to post this list in the Deep Sky Forum on Cloudy Nights (giving you credit, of course). Alternatively, if you also spend time there, would you post it, please?
I think the readers there would find your links helpful.

Don,
In addition to the post, you might find linking this article Glen wrote useful as well:

Thanks for the resource, Glen. I was looking for Barnard's list of dark nebulae just the other day....the search is over!

Which list did you mean?
I don't want to upset Alzner and Stoyan or the Webb Society.
But you can use my list and my links.

A list that is ranked by magnitude
THIS IS A MULTI-LIST OF DEEP SKY OBJECTS.
A useful tool when deciding what to observe tonight is a list that is ranked by magnitude. You can use it to find the 10 brightest objects of each type or the 10 faintest in the list.
The attached list contains 635 objects.
The 5 columns are:
1. Rank from 1 for the brightest of each type of object to xxx for the faintest.
2. Name NGC, IC etc in numerical order.
3. Type OC, GC, PN, Gxy
4. Mv the visual magnitude from 0.4 to 11.9.
5. M The Messier number.
There are:
211 OC from Lynga 1987. M45 is #1
103 GC from Harris 2003. Omega Cen is #1
114 PN from Kent Wallace and Acker+ 1992. M27 is #1
207 Gxy from de Vaucouleurs+ 1991. LMC is #1
See post #1 below for these catalogues
There are no nebs because their magnitudes are not available.
See post #4 below for the brightness of northern nebulae.
Use RCW for southern nebulae.
You can copy this tab-delimited list into MS Excel and use a data filter to find all the objects ranked less than 20 etc.
It is really a multi-list, brightest 100 or brightest 200 etc.

Steve Gottlieb
This is amazing!
6750 NGC + 600 IC observations with 13" and 17.5" scopes. 
Steve Gottlieb's
NGC/IC Observations Database Files
These are Steve Gottlieb's own personal observations for about 6571 original NGC entries (6750 total {NGC + alphabetic suffixed NGC} and 600 IC objects) all of which have been checked for historical accuracy. Outside of the NGC itself, this is likely the most complete contemporary resource of NGC observations, by a single observer, available anywhere. A hat tip and a salute to Steve!

Kent Wallace
Another amazing modern observer is Kent Wallace from California.
He attempted to observe 1064 planetary nebulae.
692 were seen.
359 eluded him.
13 were uncertain but may have been seen.
The northern PN were observed from California and the southern PN from Western Australia. He uses a 20" Dob without any goto aids.
His list is at:

Agreed! Great listing of deep sky resources. I don't think we will ever be able to see everything in this known universe....

Thanks heaps for all the lists Glen. As a newcomer I find it great to have lists of all the things I can hope to see as I go through this hobby. You have given many of years worth of observing.

Rich Open Clusters
Below are 4 very rich open clusters.
The diagrams give individual star magnitudes and colours.
Blue is on the left red is on the right.
