A little while ago Seattle Goodwill auctioned off one. I could see from the photos that the focuser had been replaced by a electric focuser. And the cable for the electric focuser was ripped off so the focuser could only be controlled by autostar. Meaning if the electronics of the mount broke, there would be no way to focus the scope. Assuming there was a reason someone donated it to Goodwill rather than selling it, I didn’t bid. Now I see it is back up for auction so whoever won the bid ended up walking away when they came to pick it up. So if you are around Seattle think twice about bidding on this one. Generally speaking there is a reason people donate stuff rather than selling it. I don’t understand why so much stuff on the Goodwill site sells for as much as one would pay on CloudyNights, buying from an experienced stargazer with good ratings who can verify stuff works and advise you of any issues.

I just came across the auction by accident. The focuser cable is not "ripped off". It is just unplugged. The original focuser hand paddle is not included, so like you said you'd have to use the Autostar to focus the scope. There is nothing broken about the focuser as it appears.

Good clarification. Still if the mount electronics are dead, you cannot focus it. Given someone donated it rather than sell it, I would be suspicious. Given whoever won the bid walked away from it and it is back up for auction again, I would be doubly suspicious.

It might keep some tinkerer occupied on a rainy evening instead of watching TV.

Not really. You'd remove the electric focuser to expose the focus shaft and attach a knob of your choice.

OR - the focuser motor is a dc motor, so a variable power supply (or battery) with a reversing switch should make it work fine with a little experimenting.

Sounds like it is salvageable at least. Just may require some extra effort.

It's a great deal for whoever bought it.

Perhaps, but it is easy enough to remove.

Depends on what the winning bid was. And if the GoTo mount worked, which I doubt. I didn’t follow it at the end to see. At $150 sure, it’s a good deal if you can get the focuser to work without much trouble. But it would have been bid up more at the end.
