Description

I collected the data for this back in August and originally processed it in APP.  Took another run at the data with PixInsight and I'm much happier with how the colours and drizzled data turned out this time.

The Coathanger fits perfectly into the RedCat field of view and there are dark nebulae mixed into the rich starfields of Vulpecula.
