Hi,
Had a crack at thor's helmet last night with average seeing.
This is 2 hours of Ha and O3 mapped as LRGB-> O3.Ha.O3.O3
Ha - 6 x 10min
O3 - 6 x 10min
10inch F4, STF8300M, Baader 8nm Filters, NEQ6, Lodestar.
Processed in Startools.
I may have pushed the saturation a bit too much, but I can't make out the amount of stretching or colour on my laptop. so suggestions welcome.
