I'm *consulting on the construction of a truss tube Dob and the rocker
box is nearing completion. Ideally, it will be stained with a
water-based but water-resistant clear stain that lets the beauty of the
wood show through with zero or minimal color/tint added.

I'm off to Lowes and/or Home Depot later today and soliciting brand
names and/or the type of product most suitable for this type of job.

I can't recommend the best finish for your application, but Dave Kriege
(Obsession Telescopes) suggests applying a coat of Johnson Paste Wax as per
the manufacturer's recommendation to the wood sections of his scopes. I do
this every year for my Obsession scopes and it seems to provide an excellent
additional layer of protection against dew.
