Description

A very rare and interesting zone,close to the border Cassiopeia-Cepheus and some degrees apart from the well-known NGC 7822 nebula. This area is dominated by the dark nebula TGU H774 P19, breaking the background (* Tokyo Gakugei University Catalog) and the deep blue vdB 2 reflection nebula. Plenty of interstellar matter,patches of grey and brown dust all around, blurring light of stars and the whole image, even crossing the dark TGU nebula in lanes.
Close to the center of image, blue star Tycho 4026:499 is the emission star HBC 328, with a dusty red lane.
The orange K2 spectral type HIP 1200 star dominates the bottom area and in the upper left corner, over vDB2, the variable type Orion stars, GCVS V0511 Cass and GCVS V0510 Cass (also emision star HBC 326, Herbig-Bell catalogue, with a red dim nebulosity ) are distinctive.HIP 1021 star has a faint blue nebulosity around.There are also numerous radiosources in the area.(X-ray)
