|Notes:||Beginning of October ... mostly clear weather,
fairly poor seeing (with the advent of off-shore winds), and the
brightening moon led me to imaging some open clusters (see
NGC 189 , NGC
433 and Riddle 4) in the north. This
is the only planetary imaged, as I thought it would be bright enough to
compete with the moon ...
