Hey Jeff,
You didn't specify but I assume your shot was at prime
focus with no guiding. For almost all shooting at
focal lengths of 135=150mm and longer, you need some
sort of guiding. Start with some manual guiding to
understand the process first then get an autoguider.
You will really appreciate what an autoguider can do.
Alan
