I was limited as to stopping-down much (this was handheld from ~30 feet).

This pic is after using LR2 removal @ 100%. Is there anything else I can do? What's the best way to remove this in PSP?

I gave up with purple fringe removal in PSP. (I have PSP X2) as I noted above use the chromaric aboration removal tool which allows you to select the color you want and the radius of correction. Look at what I did with the black bird for example. That was on the JPEG just copied out of the post.

THe advantages other than working on colors other than purple, is that you can enter multiple colors to work on, within the tool. it can do them all at once, but be careful about radius size, as it can leave the picture artificial. My approach is to leave the Dark CA in the picture as they don;t show in prints, but go after the red and green in the whites if they are too bad around the subject, but forget about background. all out of focus will have CA

A "good" example of "bad" technique - over-exposed, strong back light, busy out of focus background etc etc.
Taken with a 100mm (aperture size) so-called "ED" glass Pentax spotter with the Pentax SLR camera adapter at an effective FL of 1920mm.

Second one taken under even worse conditions (very intense glare from early morning sun just beginning to cut through early morning fog) with a APO triplet.

Absolutely! In fact, I was thinking of posting on the topic to solicit exactly the sort of expert advice that's emerged here.

In fact, this thread prompted me to revisit a shot (taken with the SMC 200mm f2.5) I had given up on. I had thought my usual practice of using Replace Color in PSE to desaturate the fringing wouldn't work well in this case--since the fringing was green and there was a lot of green in the background--but I was pleasantly surprised.
