I think Ray's thread has some mention of not worrying about the well depth. can't remember.
This is the processed Lum

Hi Alistair,
I understand - yes - you got the jet so you achieved what you wanted.

My method of attack on this target will be to adjust the exposure time
so that the 2 center bright stars are clearly separated &
then I'll take as many multiples of that exposure time - as I can.

cheers
Allan
