This image is an illustration of why the STXL-11002 is poor performer for imaging using narrowband filters.
I could have used half the imaging time with a ST-X10ME but alas the ST-10XME has a limited FOV.
9 hrs Ha + 4 hrs OIII for luminance, 1 hr each for R,G and B filters.
BRC-250 scope.
Higher resolution.
