This area around Lynds Dark Nebula 1235 in the upper left corner of the image lies in a complex of dust called the Dark Shark in the constellation of Cepheus. This area is similar to Wolf's Cave.

VdB 150 is the blue reflection nebula at top. VdB 149 is the reflection nebula at bottom. LBN 535 is also involved in this complex.

Dark nebula are opaque clouds of dust and gas in space that block the light of stars behind them. But some of the faint dust in the area of LDN 1235 may also be visible because the dust is glowing from photoluminescence. This dust glows from energy from the interstellar radiation field.

In 1981 Snell determined a distance to LDN 1235 of 652 light-years.

Lynds Dark Nebula Catalog (LDN) was created by B.T. Lynds in 1962 from studies of the red and blue plates from the Palomar Sky Survey. Lynds Bright Nebula Catalog (LBN) was created by Lynds in 1965.

VdB 149 and 150 were cataloged by Sidney van den Bergh in 1966, but VdB 150 was noted in 1918 by Annie Jump Cannon and Edward Pickering.

LDN 1235 lies 1 degree east of the brightest star is the frame, 16 Cephei (HD 209369), at right.

HD 211300 is the magnitude 6.11 star just to the right of LDN 1235.

North is to the top in the above image.
