Description

The weather finally broke and I was able to complete the Cave Nebula after collecting the first light on it around 3 weeks ago. Ha and SII were very strong, but OIII was weak so it took some extra processing work to bring it out.

Thank you to the people that run NASA APOD for selecting this image on November 14, 2018.
