Sh2-155, C9 Cave Nebula

Horizontal banding sorted. Camera into USB 2 not 3, and not through a USB hub.
Not very happy with the processing.

IC 1396 Elephant Trunk Nebula

One I often observe for HOYS but purely for imaging this time. Some horizontal banding noise from somewhere – to be resolved.

Cygnus Wall in NGC 7000

Last one was narrowband, this attempt is full colour with the CMOS camera. Also first time using NINA for capture. Looks a great tool.
Replaced image after trying demo of Topaz de-noise – excellent.
