I observed copernicus last night, with a 15mm eyepiece @ 83x, and then barlowed (2x and 2.4x) @ 166x and 200x. The seeing only just supported the high magnifications in moments of clarity, but for the most part the wider 83x view was the best.
The sun was fairly high, but the terraced walls of the crater were still very clear and the central peaks stood out nicely. The ejecta rays were already bright from the high sun and spread out hundreds and thousands of kilometres from the crater.
It's truly a magnificent crater with so much detail to take in when the air is steady. I try to imagine the view standing within the crater, dwarfed even by the central peaks, let alone the high crater walls. It would be a stunning sight.
