Cosmic Hand Nebula
Éder Iván

The Cosmic Hand or often called Helping Hand Nebula is a dark and reflection nebula complex located in Cassiopeia. This target is very faint and not easy to photograph.

I started to collect the data in 2020, but had no enough time to finish. One year later I spent 2 another night for it, ended up with 28 hours of data.

Catalogue numbers are: The reflexion nebula is vdB 9, dark nebulas are LDN1352, LDN1353, LDN1355, LDN1358.
