Description

First session for the California Nebula in narrowband. There's little O3 signal, so this is in HSS rather than the more common HOO and SHO.

Clouds have come in so I'm not sure I'm going to get more integration on this this year, but it's good for now I think, if a little noisy if you zoom in.

A complementary Ha-only version is particularly beautiful and shows much more structure.

30 subs per filter, 2-panel mosaic. 90 mins total per panel.
