Hi all. I am hoping you can help me troubleshoot this.
I have a Sky Watcher EQ6-R Pro mount. I have had it about a year, without any trouble. The last couple of times I have tried to use it, it has not been doing a proper 3-star alignment. By that, I mean it goes through all of the motions, but the stars aren't even close to where it should be. Normally, by the third star, it's pretty close. Instead, it's off by about a degree.
I tried using different alignment stars, thinking that perhaps I was looking at the wrong bright star, but I'm getting the same problem. Oddly, it seems to be repeatable, so if there was something slipping, I wouldn't expect that. It seems to go to the same places every time, and they are wrong. Ugh... And when I tell it to point at something, it ends up being off as well, but again, from what I have seen, it's always in the SAME wrong place. Yet when I tell it to park the scope, even after sending it all over the sky, it seems to go back to home, just as exact as ever, as far as I can tell.
Date/Time latitude and all of those other things are correct (including Daylight savings). It actually started happening before the time change, so I believe I can safely rule that out.
I used it during a couple cold nights (down around 0° F). Could that have damaged the gears?
Other things that might have changed: Voltage is at 14.2, with plenty of amps. I tried hooking the mount up to a marine battery and blew the fuse and had to replace it, but I am pretty sure I used it without incident after that, and things were fine (replaced with like fuse). I can't imagine how the voltage would impact it (it's definitely not under voltage), but I'm out of ideas.
Did I somehow ruin my mount? :-(
