438 is the brightest nebula in this field, with an interesting shape
like a tower with some peaks, surrounded but a red glow. Many other LBN
are included in the field: LBN 435 is the red-pink nebula on the right,
LBN 440 is the C-shaped nebula on the lower left side. The central
nebulae are catalogued as GN 22.39.0. Two spiral galaxies are present:
UGC 12181 on the upper-left and UGC 12137 on the upper-right.
