The night of the 29th I used the 6-inch on the moon, and then Jupiter, and was able to see Io emerge out of Jupiter's shadow -- a dim point, growing brighter in less than a minute. Comparing to views through my 8-inch masked reflector last night, I would say for sure the refractor is better (more contrasty) than the reflector. Though, the mirror needs a cleaning.
Seeing was not very good last night, about 5-6/10, and transparency was poor with the usual haze. Marine layer fog started to drift in around 11:00pm, so I packed it in.
