Hershel 400 Objects in Orion

Abbreviations in the CON column are the IAU versions.
The column TYPE has following abbreviations:
OPNCL = open cluster PLNNB = planetary nebula GLOCL = globular cluster CL+NB = open cluster and nebulosity BRTNB = bright emission or reflection nebula
Hubble Classification for galaxies or GALXY where no classification existed.

In the Herschel Column the Classes are:
I = Bright Nebulae III = Very Faint Nebulae V = Very Large
VII = Pretty Much Compressed
Clusters of Large or Small Stars
II = Faint Nebulae IV = Planetary Nebulae VI = Very Compressed and Rich Clusters of Stars VIII = Coarsely Scattered
Clusters of Stars
Observation Notes
1788 ORI BRTNB 05 06.9 -03 20 99.9 8'X5' H V 32 is pretty faint, pretty large and irregular in the 17.5" at 100X. It looks like a paint splatter with a pretty bright star at one edge.
1980 ORI CL+NB 05 35.2 -05 55 2.5 14'X14' H V 31 If you are like me, the first time you looked at NGC 1980, you didn't know that you were looking at an object that has a seperate designation from the Great Orion Nebula. NGC 1980 is the faint nebulosity that involves Iota Orionis, the end star of the sword of Orion. I wish I has a nickel for every time that Iota Ori has been used as a guide star!
1999 ORI BRTNB 05 36.5 -06 43 99.9 16'X12' H IV 33 Pretty bright, pretty large, round, somewhat brighter in the middle, surrounding a star. There are several dark markings in the nebula at 135X. Averted vision enlarges the nebula and the north side is brightest.
2022 ORI PLNNB 05 42.1 +09 05 12.8 28"X27" H IV 34 is a pretty small, not very bright planetary. It can be noticed in the 17.5" at 50X. At 200X, it is a greenish dot with no internal detail.
2024 ORI BRTNB 05 42.0 -01 50 99.9 30'X30' H V 28 is a bright, large emmision nebula near Zeta Ori. It is easy in any telescope I have ever used under dark skies and my old 8" f/6 would show several dark lanes winding across this nebulosity. The 17.5 incher helps a lot and much detail can be seen in the region at 200X. The UHC helps a lot and so does getting Zeta out of the field. Because of the large, parallel dark lanes, Arizona astronomers have taken to calling NGC 2024 the "Tank Track" Nebula.
2169 ORI OPNCL 06 08.4 +13 57 5.9 7.0' H VIII 24 is a pretty bright, not compressed open cluster in the 17.5 inch at 100X. What is bizarre is that the cluster members form the numerals "3" and "7". It is a shame that this is not M37, you couldn't miss it.
2186 ORI OPNCL 06 12.2 +05 27 8.7 4.0' H VII 25 Pretty bright, pretty small, pretty rich, compressed, stars of mags 10 to 13, 27 stars counted at 165X. There are several delicate pairs in this cluster.
2194 ORI OPNCL 06 13.8 +12 48 8.5 10.0' H VI 5 is a bright, pretty rich, compressed open cluster that is well resolved in the 17.5" at 100X. The cluster has a flattened shape.
