  1. At the intersection of boredom, astronomy and excel lies my analysis of the objects within the NGC (sorry if this is old news). I made these tables using the data from the NGC/IC Project. It may help in further organizing your observational data, or planning, it might not, but it's kind of neat to see the breakdown by objects within the catalog (and it was fun to put together). Let me know if you catch any errors and I can update! -Rick Some interesting findings: I knew there were a bunch of galaxies in the NGC, just was not aware that 80% of all the existing, non-duplicate objects were galaxies There are more Double Stars in the NGC than Planetary Nebulae 7840 NGC entries, but only 5724 unique and existent objects (maybe 5723, depending on NGC 1990) 234 Entries are duplicates (or triplicates) The only duplicated entries are of galaxies There are 82 entries for which objects do not actually exist 83 is probably the real count if you say NGC 1990 does not exist January-April is a great time for open clusters June-August is a great time for globulars Any month is a great month for galaxies July and August are great for planetary nebulae 257 NGC objects are stars, doubles stars or triple stars Triples, Doubles and Single Stars are fairly evenly distributed across the catalog Total Objects in the catalog by Type: NGC Obect Type # of NGC Entries Duplicated Entries # of Unique NGC Objects % of Total % of Existing Objects Most Entries by Type within One NGC Range (Ex: 1-999 or 3000-3999) NGC Range with Most Objects by Type NGC Range with Second Most Count of the Second Most Entries by Type Gxy 6271 234 6037 79.4% 80.2% 890 4000-4999 5000-5999 875 OC 678 0 678 8.9% 9.0% 245 2000-2999 1000-1999 154 GC 142 0 142 1.9% 1.9% 73 6000-6999 1000-1999 30 Star 115 0 115 1.5% 1.5% 23 1-999 4000-4999 18 Neb 111 0 111 1.5% 1.5% 47 2000-2999 1000-1999 31 Double Star 106 0 106 1.4% 1.4% 17 6000-6999 1-999 13 PN 98 0 98 1.3% 1.3% 49 6000-6999 2000-2999 14 OC+Neb 89 0 89 1.2% 1.2% 44 1000-1999 2000-2999 17 Ast 69 0 69 0.9% 0.9% 19 6000-6999 2000-2999 18 Triple Star 36 0 36 0.5% 0.5% 9 2000-2999 1-999 3 GxyCld 22 0 22 0.3% 0.3% 11 5000-5999 1-999 0 MWSC 8 0 8 0.1% 0.1% 8 6000-6999 N/A 0 SNR 6 0 6 0.1% 0.1% 5 6000-6999 1000-1999 1 HIIRgn 6 0 6 0.1% 0.1% 3 4000-4999 3000-3999 2 Neb?* 1 0 1 0.0% 0.0% 1 1000-1999 N/A 0 Nonexistent 82 0 0 1.1% ---- 19 1000-1999 7000-7840 17 Total 7840 234 7524 Neb? *refers to NGC 1990 Objects by Type and Position within the Catalog: NGC Number Galaxy Galaxy Cloud Nebula Questionable Nebula Open Cluster and Nebula Open Cluster Globular Cluster Planetary Nebula Super Nova Remant HII Region Milky Way Star Cloud Triple Star Double Star Star Asterism Nonexistent 1-999 834 6 4 0 12 49 8 4 0 0 0 6 16 23 5 8 1000-1999 646 0 31 1 44 154 30 4 1 0 0 3 13 13 10 19 2000-2999 596 4 47 0 17 245 5 14 0 1 0 9 12 17 18 8 3000-3999 873 1 8 0 2 21 1 7 0 2 0 3 15 10 0 7 4000-4999 890 0 0 0 0 12 5 2 0 3 0 2 5 18 3 7 5000-5999 875 11 1 0 0 28 15 7 0 0 0 2 14 11 2 5 6000-6999 634 0 15 0 12 120 73 49 5 0 8 6 17 6 19 11 7000-7840 689 0 5 0 2 49 5 11 0 0 0 5 14 17 12 17 Total 6037 22 111 1 89 678 142 98 6 6 8 36 106 115 69 82
