I gave CTA 102 another go on Tuesday evening with the 17" f/15 classical Cassegrain at the Naylor Observatory. The conditions, which weren't ideal to begin with, deteriorated rapidly. I'm fairly sure that I was at the right location and may have actually seen the blazar but not long after I acquired the field the sky clouded over.
Through occasional breaks in the clouds I observed a very tiny Mars (apparent diameter 6"), a 61%-illuminated Venus, R Leporis, Sigma Orionis, Struve 761, M41, M42, M43, M47, M50, M78, M79, NGC 1980, NGC 1981, NGC 2244, NGC 2261, NGC 2264, and NGC 2301 before closing up the dome.
Perhaps I'll have better luck on Thursday night.
