The seeing was horrible on the night of this observation and I had to keep the magnification to 120X and observe wider fields. There was some very nice terrain to view in the vicinity of Bullialdus. A rippled fan ran west from Bullialdus itself. Lubiniezky appeared ghosted. Bullialdus’ walls were starkly terraced and a small bright peak emerged from its shadowed center. Some more rippling ran south from König.
