As I said above, I removed the secondary and spider. I had to, to be able
to sight and take a measurement on the opposite side of the OTA.
Basically I just used what ever I had, when I got the Chesire I came up with
that idea. I guess it doesn't really matter how you do it as long as you get a
result. I assummed the tube/OTA to be pretty square, massed produced
things or machanically cut steal usually is, however mass produced and hand
cut might be a lil different.
