Hershel 400 Objects in Cygnus


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
Nebulae
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

Observation Notes
6826 CYG PLNNB 19 44.8 +50 31 8.8 27"X24" H IV 73 is the Blinking Planetary. This medium sized, 9th magnitude planetary can be located at 100X. It appears as a non-stellar blob in the Milky Way. I first saw the blinking effect in an 8" scope at 200X. If you look directly at the planetary the central star is prominent compared to the greenish nebulosity. Then averted vision will make the nebula appear brighter and overwhelm the star. Alternating between direct and averted vision will produce a blinking on-then-off effect that is fascinating. In the 17.5" the effect is unmistakeable. There are several other planetary nebulae that have the right central star to nebula brightness to show off this effect.
6834 CYG OPNCL 19 52.2 +29 25 7.8 5.0' H VIII 16 Pretty bright, large, pretty rich, compressed, and somewhat triangular at 100X. I counted 38 stars with one dark yellow 10th mag near the center.
6866 CYG OPNCL 20 03.7 +44 00 7.6 7.0' H VII 59 Large, rich, considerably compressed and well resolved at 165X. I counted 62 stars from 10th to 14th mag.
6910 CYG OPNCL 20 23.1 +40 47 7.4 8.0' H VIII 56 Pretty bright, pretty large, pretty rich, compressed, 39 stars counted at 100X.
7000 CYG BRTNB 20 58.8 +44 20 99.9 120'X100' H V 37? is the North America Nebula. This large area of nebulosity needs an RFT to be seen in its entirety. A dim glow can be seen in the area with the naked eye and 10 X 50 binoculars at a dark site will show the North America shape. In a 4 1/4" f/4 with a 20mm Erfle and a UHC filter, the nebula is very bright and very large, filling the 1.5 degree field with nebulosity. The brightest section is "Mexico" and the Pelican Nebula (IC 5067) can be seen nearby.
7008 CYG PLNNB 21 00.6 +54 33 12.0 86"X69" H I 192 is a pretty bright, pretty large, roundish planetary at 200 X in the 17.5". It has several irregular bright spots and three stars are involved in the nebula. There is a nice blue and gold double star at its' edge.
7044 CYG OPNCL 21 12.9 +42 29 12.0 3.5' H VI 24 Faint, pretty small, Elongated 2 X 1 in PA 90, not compressed, not rich. I counted 16 stars and a backround haze at 135X.
7062 CYG OPNCL 21 23.2 +46 23 8.3 7.0' H VII 51 Pretty bright, pretty small, pretty rich, compressed. I counted 26 stars at 165X in this nice cluster.
7086 CYG OPNCL 21 30.5 +51 35 8.4 9.0' H VI 32 is a bright, pretty large, rich and pretty compressed open cluster at 100X. It is a nice cluster with about 60 stars resolved.
7128 CYG OPNCL 21 44.0 +53 43 9.7 3.1' H VII 40 Pretty faint, pretty small, compressed, not rich, this is a lovely ring of stars at 135X, with a nice orange member of about 12th mag on the east side.
