I have to ask you about the[b] star RZ Cas[/b], 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. [b]Could there be a hidden cluster there, too?[/b] What do you think, Jac?

ThanX Ann

I don't think so. There are individual stars, but no cluster like in LDN 1358 (left).

No? :(

It looks quite special.

Fantastic, Jac! What a hidden gem of a cluster! :D
