Description

California Nebula (NGC 1499) in Ha with a colour camera

-----------------------

I am currently working on creating an HaRGB image of this amazing emission nebula and thought I would share my H-alpha image.
This is a combined 7.5 hours of imaging in H-alpha (7nm) with my colour camera in 5-minute exposures.
I'm happy with the amount of detail I was able to get, even though I'm using a one-shot colour camera and not a mono camera.

-----------------------

Total imaging time: 7.5 hours (90x300")
Telescope: Sky-Watcher Evostar ED80 Black Diamond
Camera: ZWO ASI294MC Pro
Mount: Celestron AVX
