Description

IC443, the Jellyfish Nebula, imaged during 2 nights, combining 1h with the old Nikon D70s (modified DSLR) and 9h with the more recent but non-modified Nikon D7000.
Unsurprisingly, the Ha signal is stronger on the D70s, however only the red channel contains information, while the response on the D7000 is much more balanced.
