Description

A first look at Orion using narrowband H-a and O-III filters.

This image is lacking H-a data with only 24 frames of 60s, before the clouds moved in.

The sky was also, not very stable with high clouds and higher HFR.

H-a data:

Focus: 10487

Mean Adu: 1815

Hfr: 2.49 (High) ~ 1.8 is ideal for my area.

Stars: 142

Note: Core over exposed, next session, reduce X to 30s.

and as always, major halo around bright stars due to RASA's great performance.
