Thanks for the heads up. I got my Coronado SM40 out and wow, it is a huge prom! Probably the biggest I’ve ever seen that I can remember. Also saw one on the surface at the 6 o’clock position about a third of the way in from the edge. It was U shaped. There was also a small but bright prom on the limb at 7 o’clock position.

Best view and magnification with the SM40 was with a Tele Vue 15mm Panoptic giving 27x at 1.5mm exit pupil. I normally used the Cemax 25, 18 & 12mm but today the view in the 15 Pan was ‘just right’.
