I just bought a ZWO AM5 mount. It wouldn't connect. The answer was simple. Use the Port Selector. That night someone on Chat Support referred me to this page which told me nothing. IMHO, this page, and that for any other mount requiring the Port Selector be used should say so. Otherwise this is little more than an ad page. I realize this is all in the manual, but I shouldn't have to scan the whole manual to find it. This step was not necessary with my previous mount, a Celestron AVX using AUX driver.
a good product let down by a poor P.A mechanism...
having owned an AM5 (and now AM5N) for several months now I am generally happy with the quality and performance of the products.
my only complaint is with the alt/az adjustment mechanism for attaining Polar Alignment.
I find that the coarseness of the threads on both axes to be a barrier to a quick and accurate alignment, particularly in the Alt which suffers from
significant backlash when changing direction, this especially leads to a challenge to get the Alt accurately aligned.
I hope in future ZWO works on this to make P.A easier and more accurate.
