The seeing was being kind and allowed me to get a closeup of the plage region using the 100mm Tal refractor at f28 (using the Airylab 2.79x telecentric. I'm pleased with the level of detail here. Next time conditions allow i'm going try the above setup but with a 1.4x barlow after the filter stack to see if I can get close to f40 to see if this improves detail.
