When I first started out with my iEQ45-GTN I was getting the same error on some nights and other nights I was not. I sat and messed with that mount for hours, turning it off, on, disconnecting, reconnecting, you name it.. I finally went to a start party our club was having when the error came up again. I asked around but no one really knew about it because the iEQ45 was so new. later in the evening another club member came in with the same mount. We talked and he laughed... How did you setup PA?? I went through my setup only to find out I was completely wrong.... That is when I found the nice polar app from iOptron for the iPhone. after PA I was able to guide!! Not very well, but I was on my way.. That same member took the time later to go over checking the polar scope, making sure it was calibrated to the mount. After making changes to the polar scope my guiding was A LOT better. Shortly after that PoleMaster came out and I have never looked back..
I have recently purchased a new mount because of a larger scope and heavier camera train, but I still use that iEQ45. With proper setup it works wonders for short focal length scopes. (I use a Stellarvue 80mm triplet on it) One thing with the PoleMaster, all you need are different adapters for different mounts. $25-30 tops and you are up and running. Align one mount, take the camera off and onto the next. \
Listen to what is being said here, they know what they are talking about. Polar alignment is critical in AP there is no way around it. (Then we can start to talk about cone error.... But there is an app for that too.. )
Remember this is a hobby, have fun with it, learn from it and you will have years of enjoyment.
