Some light polution, just before total darkness, not much time as moon ready
to pop into view. Outer edges showed well, tho nucleus did not resolve, looked
brighter and more stars than in my smaller scopes. Spent more time seaching out
NGC 7009 Saturn Nebula, again was brighter than smaller scopes, conditions not
very good as haze, 250X did show some shape, but will get a better view when
clearer and closer to transit.
