The Cave Nebula is a diffuse nebula in the constellation Cepheus, within a larger nebula complex containing emission, reflection, and dark nebulosity. It is widely known as the Cave Nebula (Sh2-155). This nebula is an ionized H II region with ongoing star formation activity, at an estimated distance of 2,400 light-years from Earth.
I used narrowband filters to help fight severe light pollution in the Detroit area.
Follow me on Instagram if you would like to see what's possible to be captured from our own backyard and to see what telescopes I use.
Hardware:
Imaging Telescope: Explore Scientific 127mm ED Refractor (952 focal length)
Imaging Camera: ZWO ASI1600MM Cool
Mount: Celestron CGX
Total exposure time: 26.2 hours
Note: A lot of people ask this, but how does my telescope stay on target if the Earth rotates. My camera and telescope sit on a motorized mount and with the help of computer software, it stays on target.
Amazing! I love astronomy, but I live in an area where it's hard to escape light pollution. Curious what part of the world you live in / how remote of an area?

I know nothing of astrophotography.
How does that work- pointing a telescope at a celestial object for longer than it takes the Earth to rotate?
High latitude? Non-contiguous time?
