Is the LPI sensetive enough?

John, I would say the LPI is NOT sensitive enough even with the long exposure mods it will swamp with noise above about 2s. Though with a 12.5" and OAG 2s might get you to a reasonably low mag - maybe 8 - if you ever swith to a guidescope it will not be sufficient, btw where did you get the mag 10 figure from? Also the envsiage s'ware is designed to guide meade scopes so if your mount is not LX compatible you will need more tools to fake it, Ezstyles has written up how to do that if you need to got that way (he drives and EQ6 with Envisage/DSI).
Based on my recent struggles with long fl autoguiding I would very strongly suggest a mono camera for guiding, the QGuide looks very promising, DSI pro series is good too.
JohnG you will share your experiances with us won't you - I am seriously thinking of jumping to this OR doing a chip swap on my Orion...
