first try at binning

[toxic]

when binning at 2x2 for S2 and O3 how do you aligne them with HA 1x1 when they are half the size do you just resize them to the same size as the HA 1x1 .

Good question, and one I'd like to know the answer to too.

I think ATM I'd have to re-bin my Ha to match the [OIII] and [sII] but that rather defeats the point of 1x1 Ha.

Hmm.....I think some of the photo editing software can do an up-res, but whether on FITS i don't know.
