The subtle glow of the star clouds and nebulae offers an intriguing sight. One of the brighter clouds, visible from my latitude, is the Cygnus Star Cloud. The sky between Albireo and Gamma Cygni appears like a glowing oval. An interesting feature is displayed by the star field just NE of Eta Cygni. The smooth Milky Way glow seems to be disrupted at that location, as it shows a mottled appearance to the unaided eye. The binocular view reveals a multitude of star associations. The brightest stars, beside Eta, are 27, 28 and 29 Cygni (see the labelled sketch). Some of the star associations are real clusters. Such is the case with NGC 6871, which appears like a 1 degree long star chain, starting S of 27 Cygni, and running first N and then NE through 27 Cygni at 28 Cygni. It is unclear to me where NGC 6871 actually ends. A nice double star, called Beta440, can be found just S of 27 Cygni. A small cluster, called Biurakan 1, can be found just E of Beta440. Another cluster, NGC 6883 can be seen at 1° E of 27 Cygni. My pair of binocular just show NGC6883 as a small brightening in the Milky Way glow. Another interesting star chain starts with 29 Cygni, which first runs S and then bends to the W and back to the N. Many of these stars in this particular field are very young supergiants, and members of the Cygnus OB3 association, making part of the Orion-Cygnus Spiral Arm at a distance of 5.700 l-y.

Thanks for adding the second version that you labelled. I'm interested in seeing how much of this I can see in binoculars. Great stuff Rony!

[Re: rodelaet]       #2622513 - 09/03/08 10:46 PM Edit   Reply   Quote Quick Reply   Rony, I spent about an hour hanging around Cygnus last night when I did the Coat Hanger. I can see why the Sky Window is so good. I was simply amazed at the detail of light and dark areas of the Milky Way at 8 power that I cannot see any other way. I wonder how to sketch in many cases, however, because the sky fields are so extensive. This little machine is flat out wonderful for sketching. I think I got 3 more orders for the company tonight by just taking it to a local meeting for some "gazers" to try out.

[Re: rodelaet]       #2850587 - 01/07/09 11:11 PM Edit   Reply   Quote Quick Reply   Rony, I do not know my way around all of Cloudy Nights as well as I would like. It will take some time. I really appreciate this sketch immensely. NGC 6871 and its environment have been a favorite field of view for the past three years. I attempted a description of this region of Cygnus in my second observing report, "Between Fog and Rain," on January 4th: At the base of the Swan's neck, to the NE of Eta Cyg, is one of my favorite views--NGC 6871, a bright, elongated cluster and, about 2 degrees more to the NE, a parallel "copycat" asterism of stars in the same FOV. Open cluster NGC 6883 in between is no-show. Oh well...some other time maybe. That's all I can do with words! And I've been trying to speak and write some kind of language for over 60 years. Keep up the good work!
