Perhaps my last northern object for a little while. I have a backlog of local data to process!
This is the Cave Nebula in Cepheus, an interaction between the Cepheus B molecular cloud and a group of large, hot stars. It's a great mix of emission, dark and reflection nebulae. There is also a group of Herbig-Haro objects (168, 169, 174) towards the bottom of the image at about 7 o'clock.
The gear used was a Tak FSQ-106ED on a Paramount ME with a QSI683 camera. This was a total of about 18 hours of 900s LRGB subs.
Processed in PixInsight and drizzle upsampled from a native resolution of just over 2 arcsec/pixel to around 1 arcsec/pixel.

Constructive criticism welcome. Some might find the colours a bit much?
Cheers,
Rick.
