Jeanette,
If I can get 4mins out of a wedged Meade ETX125 @55mm, you should be able to get 5-6 mins out of the EQ5, it has to be a better at tracking than mine.
And thats without drift aligning or anything. (Mind you, I now know what the SCP looks like through my 26mm eyepiece, so my starting point is good)
