The mount is a Mead Magellan II. When powered on it blinks 3 times which should indicate the revision level.
The mount is reasonably well aligned to Celestial North. Using the drift method and camera taking a picture every 10 minutes there is almost drift on either stars close to the azimuth or horizon in a 30 minute period. Next the Magellan alignment procedure is completed. This should set the scope up for 'push to' operation.
However it does not. After many cycles and tests I have some observations and the result of one experiment.
The first observed issue is when an object is selected and the scope manually moved to what should be the position the object is no where to be seen. I decided to test the accuracy of RA and Dec changes separately. I set the scope on an object and then moved the mount either RA only or Dec only. When moving in the RA axis the the Dec value remained steady. However when moving in Dec axis the RA value changed significantly. I assumed that the mount was trying to adjust for a perceived misalignment in the mount orientation. Since the changes were extraordinary, on the order of hours over a 90 degree Dec change this was not the result of polar alignment.
Now the experiment. I first aligned the scope on the first target star. I then rotated the Dec axis to 90 degrees North and proceeded with the alignment procedure. This produced much better results. The procedure above produced relatively much less interaction between isolated Dec axis or RA axis movements.
Has anyone else had similar observations?
Is this a known issue with this revision level?
Are there later software revision levels available? Is so can someone proved a link?
Thank you all in advance. Dan
