All,

IC443 - A Supernova Remnant in Gemini. 6 x 30 Minute Subs in Ha.
253mm f/6 Newtonian, STL11000M and 6nm Ha Filter.

Processed as follows

1) Calibrated
2) Aligned
3) Hot Pixel Repair
4) Dead Pixel Repair
5) Unreliable Pixel Repair
6) Sigma Reject Combined
7) Kernel 3x3 Filter
Cool

Levels
9) Curves

Extremely Bright Moon nearby so I think this still needs more signal.

But comments welcome.

Regards

A nice one Bill. The paracorr seems to do a credible job on that newtonian
despite the size of the chip.
