Description

Simeis 147 and Sh2-242. 2-part mosaic. Canon EF 200mm f/2.8L II USM with Astrodon 5nm Ha and Red Continuum filters. Atik460ex(mono).

Eastern half:10min x 28=4h40m (Ha) + 10min x 25=4hr10m (Red Continuum).
Western half: 10min x 31=5h10m (Ha) + 10min x 30=5hrs (Red Continuum)

This was a project over two new moon star parties, but the conditions were marginal because of thin clouds and smoke from the Rough Fire near Fresno (1st month), and of rather high moisture level in the air for October (2nd month). The continuum frames were used to suppress the stars slightly and bring out the nebula.
