W & J Herschel - 450 DSO
The 410 DSO list does not include some "clusters + nebulae" that are fainter than magnitude 7.
I decided to create a new list of 450 DSO (see the attached spreadsheet file) that includes them.
The William & John Herschel 450 deep sky object (DSO) list is made up of:
73 Herschel open clusters brighter than magnitude 7.0
74 Herschel globular clusters
66 Herschel nebulae (some are also clusters)
58 Herschel planetary nebulae
161 Herschel galaxies brighter than magnitude 10.5 and
18 objects in the LMC, SMC, M31 and M33.
