Its not the overall pe that is the problem, it's the 2 arc sec jumps every 10.2 seconds that are. This jump is a function of the design...some EQ6's are much worse than others (like mine)and it is a well known issue. It wouldn't matter if the pe was 40 arc secs as long as it was slow and regular - this would only be 5 arc secs a minute or 1 arc sec every 12 seconds...easy guiding. It is the fast errors that are built into the mount that are a problem at longer focal lengths. If I was using an ED80 then the error couldn't be seen. This is the thing, most people imaging with eq6's (note, most, NOT all) are using short focal lengths.... From all reports I can find a GPD2 will have a slow regular pe that is easily guided. If so it will do me until I can save the money for a Tak, AP or similar!!!!!
cheers
