I was at the Grand Canyon star party last month and a ranger showed me a trick for focusing on Jupiter.
He said to use a Bahtinov mask on a bright star first, then swing over to the planet without touching the focus knob, which gave me my sharpest planetary image yet, so what other focusing hacks have you folks found helpful?

Oh that Bahtinov mask trick is a classic! I read somewhere that using a camera's live view zoom on a star works great too, you just zoom in digitally and tweak until it's a tiny point.

But how accurate is that compared to the mask?
