Good on you Mike.
While I'm still dabbling with some solar stuff, I too am at that stage where I need to get back into my spectroscopy.
I've had such a run of bad weather and clashes with other things that I needed to do that I've kinda lost touch... out of the groove so to speak. Its just too easy for other things to get in the way.
Glad you're back in the saddle.

Do you think the PST hotspotting is to do with the 40mm aperture, or a property of the filters themselves?

Its a property of the PST itself. I'm not sure what part causes it, but its not the aperture size. I use the SM40 Ha filter (that I originally bought to double stack my PST) on the front of my ED80, and the images are as flat and uniform as you could ask for.
