This is a faint one and I put in almost 20 hours of LRGB from a Bortle 3 site. The blue reflection nebula in VdB9 in Cassiopea is lit by the star SU Cassiopeiae. The dark nebula LDN1355 and LDN1357 in the foreground form a "helping hand". Imaged over four nights in Calstar 2023 (Lake San Antonio, CA). Higher Quality at https://www.astrobin.com/4x5jad/
