Helping Hand in Cassiopeia
Explanation: Drifting near the plane of our Milky Way galaxy these dusty molecular clouds seem to extend a helping hand on a cosmic scale. Part of a
local complex of star-forming interstellar clouds they include LDN 1358, 1357, and 1355 from American astronomer Beverly Lynds' 1962
Catalog of Dark Nebulae. Presenting a
challenging target for astro-imagers, the obscuring dark nebulae are nearly 3,000 light-years away, toward rich starfields in the northern constellation
Cassiopeia. At that distance, this deep, telescopic field of view would span about 80 light-years.
...nice treasure chest...
LDN 1358 (AllWISE)
Fantastic, Jac! What a hidden gem of a cluster!
I have to ask you about the star RZ Cas, the bright-looking bluish star near bottom right in the APOD. The star itself is a very modest quite nearby A-type star, and the nebulosity next to it has nothing to do with the bright-looking star.
Yes, but the nebulosity itself sure looks interesting. Could there be a hidden cluster there, too? What do you think, Jac?
