What eye pieces are you using? I hope your not trying to use a
series 5oo 4 mm ep <<< very bad lol
If everything else is fine you should be able to focus on a 1st mag star.
I have an 8" f6 dob and don't have any trouble.
I see your scope is an f4. I don't know what kind of difference that makes but I'm sure one of our experts can help you out.
