Description

Sh2-188 is a planetary nebula in Cassiopeia. It is often called as "Shrimp nebula" or "dolphin nebula". To me it is more like a shrimp than a dolphin. It is a target for narrow band on full moon. I just want to shoot Ha and O3 to make a HOO image together with RGB stars. It is quite faint and small, I could use more integration time.


Subs:
Ha: 20x1800s
O3: 24x1800s
R/G/B:  30x120s each
