Hi Ron,

When you get back from WSP, and during your next CNC run, whenever that
is, I’d like a 3/4” travel drawtube with compression ring fitting. I’d

also like to order a 1.5” extender drawtube in the 2” size, with a
compression ring fitting. You might as well send them both at the same
time, which will save on shipping, etc.

I can pay by Paypal, if you like, or I can call in a CC.

No rush.

Best,

Jimbo
PS: I had the webcam out a couple of nights ago, and parfocalized it to
the rest of my eyepieces, so I’m down to 2 focus positions: “DSLR” and
“everything else”. “everything else” turns out to be real close to 1.5”
away from “DSLR”.
