Ceres disk visually possible?
Has anyone ever observed Ceres as a disk visually? I know it can reach an angular diameter of 0.85", which is comparable to Io (1") and Europa (0.86"), and these can be seen as disks with an 8" scope in good seeing at high enough power.
I'm thinking that with a 10-12" telescope at very high power under excellent seeing, it would be possible to see Ceres as a tiny disk when at maxmimum angular diameter.
Anyone ever attempted this? What do you think?
