Great seeing today and a nice small AR. Tried the SM90II again and got better results.

That is an excellent set of images Pedro! Clear skies here too, but sun is low in the trees on the roofline for me this time of year.

Thanks Raf and thanks Mark for the SPOD

I guess you're right, this might well be the last AR of this cycle, or maybe not
