After an observatory refurb I have been getting my mount back into working order and that has meant doing the polar alignment all over again.

I have the EQ8 without the polar scope so have been using the Synscan v4 routine instead. Only problem I can't get around is that each time I complete the 3 star alignment it keeps telling me the errors from the previous alignment are being applied.

How can I clear the previous error values and start afresh. Seems little point otherwise!

I don't have the Synscan system, but is your error message the "NPE Error"?

According to the v4 handbook section 11.7 "Non-perpendicular error (NPE) occurs when the mount’s two axes are not orthogonal." It says the value for Cone error and NPE can be user-set , and "Generally, NPE is very small and can be ignored(Set to 0) in most cases unless superior pointing accuracy is required"

Regards,

hi have you figured out the message on the synscan v4 I still get it but I have just found out that if I put the time to +01.00 and have it on daylight savings it brings the target stars in nearer to the center of the eyepiece don't know how your ailment is are you bringing the stars in from a long way or are they near center wold be great to find out if you have solve this problem. please get back to me and we can see if we can put our heads togeather and work out the message. I do know it dosent display the message if you set it up in the home and pick 3 stars but don't re-align the mount as you wold on a star see if yours dose the same

Think I have found something out try clearing the pec data. When you set the mount and do you set up if the mount comes up with the message park the scope the clear the data the do another alignment
