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.
