My 8" Compact Travelscope. (Ideas taken from Gary Seronik's
article in Sky & Telescope. PDF
Version Unfortunately, Gary's article didn't have a link to plans, so
I had to work out how to build it on my own. This was a fun task, even
though it was sometimes frustrating.)
One major difference is that Gary's was an 8" f/4.1, where mine is an
8" f/6.25. This gave Gary one luxury of a shorter scope, making
The preliminary plans. (Like any good carpenter,
I deviated a little from these, but not much.)

Here are some pics of making my scope
The beginning. Secondary cage octagon's have been cut!
I decided to make a homemade focuser. Found a plan for a Crayford-style
using PVC pipe. Took a bit, and like the rest of the scope, needed a

Easing the focuser parts together. ;-) It's a tight squeeze to
get the sink-drain pipe down into the PVC. A little TLC always helps!
Adding the focuser to the secondary cage.
The completed secondary cage, with mostly completed focuser. Just need to
attach the knobs. Until then, a little rubber tubing makes turning it
The completed mirror, rocker and ground boxes. Still a couple issues
surrounding balance, but otherwise complete.
