Slewing sound frequency

Hi Brian;

I have had the 600 GTO for close to two years now getting mine in Oct 19998. The sound on occasion does change and at times it depends on the balancing of the weights or the EP you are using. The slight change in noise is there but of absolute no importance and will not effect the accuraqncy of the slew. SO ENJOY! Howard Lazarus

Hello,
I am a new owner of a 600EGTO mount and have had a couple of opportunities to use it. One thing that is obvious is that I am going to need an illuminated reticle for the callibration routine. Also, since my left eye is next to useless, I will be anxiously awaiting any polar alignment scope that may be made available (next to impossible for me to focus just one eye to infinity through the RA shaft thus seeing Polaris is very difficult for me). Anyway, I have a question for the veterans here: Is it normal for the mount to fluctuate in sound frequency as it is slewing to objects? I have the slewing speed set at 1200 so I would have expected a uniform motor 'whine' as the slewing is taking place. For the most part that is what I get but occasionally it will briefly go down in frequency (as though it is slowing down) and then recover to the steady whine that I presume represents the proper slewing speed. It seems to be OK regarding the pointing accuracy so maybe I am being picky with my observations?..... Any others here observing the same thing and is this normal? Brian Herbst
