LRGB Workflow and HA continuum subtraction

Brent Jaffa

ADAM,

If you wanted to add HA to your LRGB workflow  using your HA continuum subtraction methodology; would you add it before

SPCC (LRGB workflow step 6) or after SPCC.

Thanks,

Brent

I would certainly color calibrate my RGB data before adding anything to it... it would be weird to add Ha and then run SPCC. With the GAIA database as the reference... it would decrease the Ha contribution because SPCC would return values that try to balance out the excess red you put in (to the RGB).
