Object name: SH2

Designation(s): SH2, 132_LBN473,

SH2-132/LBN 473 is an emission nebula in southern Cepheus. It's a bit big for my FOV but I never let that stop me before. Galaxy map puts its distance as a bit over 10,000 light-years. It is usually seen in narrow band images often using H alpha for the luminance channel. This tends to miss the rather strong OIII emission and its reflection component making most photos of this image appearing mostly red. Normally the OIII is rather cyan in color being rather equal in my blue and green filters. Here the blue was stronger than the green. I assume this means there's a reflection nebula component to this nebula as well. Or it has far more H beta than is usually seen.
