Description

This is Sharpless 2 155 or "The Cave Nebula".    Sh2-155 is an ionized H II region with ongoing star formation activity, at an estimated distance of 2400 light-years from Earth.  This was my first attempt at 1800 second exposures with the CDK17 and L500, but it will not be my last.  I think the level of detail that I was able to capture in the nebula is just incredible.  I adapted Steve Miller's (YouTube Entering into Space) SHO techniques to process.  Nebula is SHO only and stars are RGB.  Feeback welcome.  Thanks!
