Quote:Greetings to: Philip Neidlinger (and all others...)Well, the above post from ur7x pretty well sums things up right now. I am an Alt/AZ user, and I love it !!! Andrew Johansen (Australia) and I are still doing tests, and he is studying the results. I just sent him some new data this morning. This, of course, is studying the Polar alignment issues...I am sure this will all work out. The interesting part will be what is done when Andrew figures it out. So far, we have not had Meade in the loop (unless they are following this thread). If you are looking for a polar mount, then i would suggest a little patience for a few more days, and lets see what Andrew comes up with. We have an active user here (Dennis and Kevin) that are polar users. And their new (replacement) Audiostar should be to them in a day or so, and we should then acquire some more data. Then we will all know more.
I lost count of my scopes. Now I just want mobility. I came, I saw, I bought some interesting accessories, and put names to faces: NEAF 2012, ASAE 2012, SWAP 2013, ASAE 2013.

Quote:And for the love of Galileo, can't anyone just do a star trail PE test on one of these things?All you have to to is plop it down in equatorial mode with a lousy polar alignment, point at a star overhead, hook up a camera and let it go for 30 minutes with the shutter open. That's it. When you look at the image, the stars will have been drifting north as a result if the poor polar alignment. Periodic error gets recorded as wiggle in the star trails. See, it's easy. -Rich

Quote:I did another indoor test and listened up against the underside of the mount since it was tilted for EQ. That's about the only spot I could hear anything. The drive noise was faint, but steady - no change in pitch, or anything like that.

Quote:This is progress! What was the focal length? What we want is image angular size per pixel. So that means figuring out how wide the field of view is in your telescope, then rotate the image to line up with a vertical or horizontal marker, then find the coordinates of high and low peaks and multiply by the angular size of the image width divided by the pixe size of the width.Longer trails are needed, though. It's best if you can get three revolutions of the worm, and that makes it possible to see what the periodic element is.-Rich
