Need some sound advice...

Ugh, the #2 problem that I have seen with GPS scopes has been LNT modules that have been installed upside down after the original owner installed an upgrade. It is a forgivable mistake, it looks right upside down, but it's upside down.

The end result... Scope is fixed. It was incredibly mis-aligned. ( I am pretty convinced it was unloaded due to being so 'out of wack'.) Virtually impossible to collimate. I ended up replacing the collimating springs and re-centering the secondary mirror. I used temporary shims to get it as close to center on the corrector plate as I could. (Thanks maadscientist) Using Dr. Sherod suggestion I acquired the smallest eyepiece I could find and removed the lenses. Inserting it in the OTA, I was able to re-align the optics. It worked.
Before the adjustment, I focused the scope on some wires hanging on a light poll about 100 yards away. They were totally blurry. After the adjustment, I could read the writing on the cables. I cannot wait for a clear night to 'fine tune' it...
