Updating performance with Ha Filter

having to rewrite this as my stacking was botched.... of note turn off deepskystacker color calibration .... it gives terrible results

pic 1
5 min sub Ha filter prawn

pic 2
5 min sub M83 Ha..... note that neither deepskystacker or pixinsight could stack these

pic 3 13 frames 5 min subs.

these taken 0 gain 30 offset

will try again with 60 gain to give similar well depth to my qhy9......now done per edit

pic 4
gain 60 offset 30 high gain mode .... Hydrogen in M83
now we have a workable stackable image , 5 min subs.
with processing this could be integrated into an RGB image
RECOMENDATION use this higher setting for narrowband work.

pic 5
Ha added to M83 plus a bit of processing to bring up detail


i think we are done here.
