This image of IC443, The Jellyfish Nebula, was acquired using an STL11000 CCD camera
on a Tele Vue NP127is 5" f/5.2 refractor.
The luminance channel is a stack of 16 eight minute exposures taken through a Hydrogen-α filter,
while the color channels are each stacks of 6 eight minute exposures taken through red, green and blue filters.
The individual source images were calibrated, defect-corrected and stacked, and the luminance channel was Gamma scaled,
the resulting files were then color combined and auto-balanced all using AIP4WIN V2.
This image is cropped from a much larger framing showing the entire region.
