Description

This was taken over two nights.  Both nights the seeing was average or slightly below, but the second night had some wildfire smoke to deal with.  The Sii and Ha data overlap quite a lot, and the stacks look nearly identical.  This presented a new challenge for my processing.  Nearly 2/3 of the Oiii data was collected on the second night through the smoke.  The pale "V" shape center-right should be a richer blue but I couldn't get it out.

Dec 7, 23 Edit: Somehow I missed 'Pa 6' (discovered in 2005 by @DanaPatchick), the small planetary nebula to the upper left of the IC 1311 star cluster.  I'm shocked it revealed itself from my terrible skies at such a short focal length.
