Usually, these descriptions are short, but I've decided to wax loquacious in this one. When searching for cool objects to photograph,
LBN 553 showed up on Sky Safari as a medium to small object with no picture available. Now, LBN stands for Lynds' Bright Nebula (after
Beverly Lynds, one of the more famous female astronomers) and the description reads, "LBN 553 is a Bright Nebula appearing in the constellation
Cepheus." At this point, I'm thinking, "Whew, so glad we could contribute that supplemental information." The description does
add that the size is roughly 5' × 5', but with no picture or further information, the prospects here seemed pretty slim.
On the other hand, I have seen a few wide field of views of Cepheus (greater than 1.5° x 1.0°) that show this region of the sky is packed
with interstellar gas and molecular clouds. This prompted me to do a mini-sky survey just to see what other fun things might show
up in photos of Cepheus. If you hover or mouseover the picture, you will see 24 stars bright enough to make it into the Hipparchos catalog,
10 PGC, Principal Galaxies Catalogue, objects of which only two are too small for me to identify visually, 2 Lynds' Bright Nebulae, and 1 Lynds'
Dark Nebula.
Please remember that Beverly Turner Lynds was working off red and blue plates from Palomar's Sky Survey 1 in the 1960s. She carefully traced
the oulines of the objects she identified and recorded their positions using 1950 coordinates. The annotation program I use makes ellipses to
identify these positions, so it's not very easy to identify exactly what Beverly saw and traced. The only Lynds' object that seems to match these
annotations is LBN 567, and even then, the circle used here seems a bit small. In the first 300 second frame from 6 September, 2026, nothing
showed at the position of LBN 553. The dark area at RA 22h and Dec +76° 30' did show so I recentered that left-to-right
in the frame.
At any rate, this impromptu sky survey shows three areas that I find interesting. The first is that large dark area at 22h
and +76° 30'. Even more interesting is the smaller dark nebula at 21h 33m and
+76° 33'. Most interesting of all is the triplet of dark nebulae at 22h 3m and +75° 50'.
Alas, too many pictures, not enough dark night skies.
