They may have been taken through slightly different filters. There seems to be more continuum emission in the lower one, especially in the outer reaches of M31

That makes sense.

At first - I thought that it is likely to be IFN that shows as OIII feature due to funny processing, but now, after you've pointed this out (which makes sense), and with above calculation of photon rate - I'm slightly more convinced that it can be legit thing.

Would like independent confirmation though.

I think I will aim my Samyang 135 F/2 with high-speed O-III filter at that area some time in autumn. Just to see what happens

I see nothing wrong with asking a question like that.  It was clear from the paper what was being done so I questioned his interpretation.

The tone of your post was abrasive, also reported by other members; I chose to issue a friendly warning as you are new here - as opposed one of your other comments (in another thread) which was removed for being rude.
