| Description | Images | BARNARD100Barnard 100 and 101 are dark Nebulae on the western edge of the Scutum Star Cloud helping to define it. These two are the Rodney Dangerfields of dark nebula as they get no respect. Even a Sky and Telescope blog article by fellow Minnesotan, Bob King, on Dark Nebulae in Scutum ( http://www.skyandtelescope.com/astronomy-blogs/dive-into-scutums-dark-nebulae071520151507/ ) that lists 15 in Scutum fails to include either of these. In fact, except for listings of Barnard Nebulae, I find virtually no mention of these two. Poor 101 gets its top half cut off in my image further humiliating it. I need to rotate the camera to catch it all with 100. I was going to take a second frame with it and mosaic the two but weather had other ideas and it was too far west at its low declination for that to happen this year. Maybe another year. |
| BARNARD103Barnard 103, aka LDN 497 is a dark nebula about 3 degrees west-northwest of M11 and is darkness class 6 the darkest classification. In fact, after my normal stretch that turns background at this declination to about 20 in Photoshop, it was still zero in all frames. Now that's dark. Related Designations for BARNARD103BARNARD103, |
| BARNARD104Barnard 104 is a dark nebula in Scutum less than a degree northwest of Barnard 107 and 13 minutes north of Beta Scuti. There was a nasty glow from a 4th magnitude star south of the dark nebula (top of the picture). I've pretty well removed it but some of the glow at the top may still be due to the star. Hard to tell what is real and what is glare. Normally I post my images with north at the top. Since this dark nebula looks like an upside down "7" I am posting it with south up so the "7" is oriented like the numeral. I found one paper putting it at 200 parsecs (650 light-years), half the distance of nearby Barnard 110. It is considered to be a Bok globule. Related Designations for BARNARD104BARNARD104, |
| BARNARD105Barnard 105/LDN 506 is a small, dark nebula less than one minute of arc across located one degree southwest of M 11 in Scutum. I find virtually nothing on it. A general estimate of the typical distance to Scutum dark nebula is about 650 light-years. I have no idea if that is accurate in this case. The bright star on the southwest edge is BD -7 4710 a 9th magnitude star. To the west (right) of Barnard 105 is the very small, 7 second of arc, blue planetary nebula PK 026-02.1 (Pe 1-16). A 1984 paper puts its distance at 1,200 parsecs (3,900 light-years) http://articles.adsabs.harvard.edu/cgi-bin/nph-iarticle_query?1984A%26AS...55..253M&data_type=PDF_HIGH&whole_paper=YES&type=PRINTER&filetype=.pdf . I couldn't find a more recent distance estimate. It seems to contain two white stars neither at the center. They likely mask the true central star. I hadn't realized it was in the frame until I processed the image and wondered why that blue "star" was a blob far larger than it should have been. A check of SIMBAD turned up it was a planetary nebula. |
| BARNARD106Barnard 106 is the smallest dark cloud right and below center. Barnard 107 is in the center. Barnard 110 is the much larger cloud to the upper left. Somehow I managed to cut much of it out. Apparently was going for 107 and didn't pay attention to the rest of the field. The three are located in Scutum north of M 11. I found a distance for Barnard 110 of 400 parsecs (1300 light-years) but none for the other two. |
| BARNARD118Barnard 118 is a very small but very dark nebula on the edge of the Scutum star cloud one and a third degrees southeast of M11. It is in a very dense part of the Milky Way. The nebula is about the darkest I can recall imaging. With a stretch which results in a background level of about 15 in Photoshop, it was zero. I can't recall seeing that before anyplace in the sky. Just to its right (west) is the apparently much smaller Barnard 117A. It had a level of 1 at its core so not quite as dark at Barnard 118 but close. I was in for a surprise when I looked up the sizes of these two. Barnard 118 is listed at 2 minutes in diameter but the "smaller" Barnard 117A is listed at 7 minutes in size. There is a slightly dusty region that extends west about 7 minutes from it but it is very hard to see on this stretched image. The linear FITS showed it but only faintly. Try looking at only the red channel of this image and you'll start to make it out. It runs to a moderately bright blue star toward the edge of the cropped image at 1.5" per pixel. |
| BARNARD122Barnard 122 and 123 are a pair of dark nebulae in northeastern Scutum. They are also known as LDN 545 and 546 respectively. They are quite obvious when seen against the very dense Milky Way. I wonder how visible they'd be seen against a typical starfield. Both are rated as level 5 out of 6 for darkness. Both have stars seen apparently in front of the nebulae with 122 being the larger. To me, 123 on the left isn't nearly as dark as 122 but it may be due to the faint stars seen across 123. Are these stars seen through the cloud or are they in front of it? Maybe a bit of both. I found nothing to say about this. Still, they appear no redder than the rest of the stars so likely are mostly in front of the nebula. |
| BARNARD127These two Barnard dark nebulae are located in southwestern Aquila. Barnard 127/LDN 544 is much denser, therefore darker than Barnard 129/LDN 549 to the northeast. Though some sources list both as being of density 5 on a 1 to 6 scale with 6 being the greatest density. There are small nodules in Barnard 129 that might qualify but considered in its entirety it is not as dark as Barnard 127. They are the densest parts of a much larger dust cloud that covers much of my image as shown by the reddened stars that contrast with the dust free regions. Between the two is another region that is denser than many of Barnard's nebulae. This middle cloud is listed at SIMBAD as [DB2002b] G29.32-4.73. The cloud east of Barnard 127 isn't listed in SIMBAD that I found. Barnard 129's southeastern section is the darkest. This part carries the separate designation TGU H292. |
| BARNARD132Barnard 132 is a long but thin dark nebula in southern Aquila some say looks like a tadpole. I don't see it, a slug maybe but not a tadpole. At the very top of the image is the much smaller Barnard 328 both are rather sharply defined and rated as a 6 in opacity, the highest level. I was unable to find much on either of these. |
| BARNARD133Barnard 133 is a dark nebula in Aquila seen against the Scutum Star Cloud which does extend eastward into Aquila. It is rated at opacity 6 which is the highest level. Though to me only parts of it rate that level. It stands out clearly against the star field both visually and photographically. I found no distance estimate for it. Considering how few stars are seen against it I suspect it is rather close at less than 1000 light-years, maybe a lot less. But this is a pure guess on my part.
