Your LPI will usually come with a "par-focal" ring. The idea being that you work out focus with the LPI, then insert and eyepiece and find out where it comes to focus by sliding the eyepiece in and out by hand, then tighten the parfocal ring once the focus is achieved. Then you can swap them back and forth as needed.
Thanks I do have the par-focal ring and I forgot about using it, I was using a 20mm EP. I even tried to line up Saturn in the talrad while watching the screen of the laptop while focusing with the LPI in and I just got a black screen I thought I would get something I have the talrad well aligned to the scope Next chance I get with the Moon I will try that it might be easier to get right

One thing though .... you can see the sky???? I've been back home since Sunday and I've seen two patches of blue. There has hardly been any rain although I can hear water gurgling in the downpipes as I type. Ahhh, the joys of the cloud coast.
Yes I can see the Sky tonight I am in a little shock
