Making use of the clear nights! I had a go last night with the telescope on the wedge for polar alignment. I got close first then I found a little bit of a cheat. I told the telescope to "go to" Antares. When it had finished and stopped on where it thought it was, Instead of using the drives to center it in the eyepiece, I moved the wedge. This seemed to work as my star trails are now a lot shorter. More practice is required, but these shots are encouraging.
I think the remaining star trailing is caused by worm drive error or maybe polar alignment is still out a fraction. I am also looking up something I don't yet understand, called, "Periodic error".
