Might try the StarFinder Yahoogroup. But there's been no support for the Magellan for ages. The scope itself is very dependable--I mean there's not much to go wrong. The Magellan? It can work competently as a digital setting circle computer. The rest of its features were never really "there."

Handheld what? The original was an AC synchro drive. You can put digital setting circles on it or add an AC drive corrector if you can find one. The DC model could be purchased with the old Magellan HC, which added DSCs and a few other features that semi-worked. You can't really plug anything else but the Magellan II into it.

Actually, I found the DC version of the drive was quite unreliable. Also, the big chrome knob to lock the Dec. quit working after a while, no matter how much I tightened it.

The Magellan I had never worked right. Although bought new, I eventually took it apart and found a bunch of loose screws inside!

The scope is rather crude but the one I had had a great mirror and I wish I hadn't sold it, but you know how that goes! I still have the mount out front, decorating my planter! Overall, these scopes were very good for the low cost of them. GW

Ps - Drive problems were that the clutch would slip and the drive would not turn the scope - often - and then later, the motor quit running at the right rate. GW

Mostly just from the heft of carrying it outside. I used mine for years after the drive quit. It was a great scope overall. GW

I m hopeful that the one in my living room will prove workable. It sure is big.

Never found this to be much of a problem. The clutch was adjustable, and I was always able to do that suitably on any of 'em I encountered. As for the Magellan, yeah, as I mentioned, it was never quite there.

I doubt it. As I said: simple and reliable.

What happened on mine was that somebody made the clutch too tight, before they sold it to me, and it was actually clicking the spur gear teeth over the worm. I did not know at first that is wasn't supposed to do that - this was quite some time ago! GW

Is the focuser plastic? I have a metal one on my Starfinder and it works fine. The immediate upgrading of every focuser that comes stock is a relatively recent phenomenon.

The focuser on mine was pretty bad! It had a 1.25" holder and then I could unscrew that and stick a 2" eyepiece in it. It would not stay in place at any setting, regardless. It looked like metal but if it was, it was the cheapest pot metal in the universe. I never replaced it though, I just lived with it. I got a lot of use out of that scope, so I would not want to run it down. GW

I used A LOT a 1994 Starfinder 8" for many years, still do at times. It still had the AC drive, but I got the inverter they sold at the time with the 12v plug, variable speed controller and fast/slow buttons. It was a must, because the drive took a bit to resume tracking after I moved the tube; so I just waited for the clutch to engage, and centered the object using the fast/slow buttons. It took a couple of minutes, but tracking was decent then.

So bad clutch yes, but I could track; bad focuser yes, but I could focus. Optics were optimized for visual observation, with f/6 focal ratio and 18% obstruction. I have used it mainly for planetary observations, and it was (is) AWESOME. Great value for the money overall, perfect for me, but I would not suggest it for imaging.

The mirror is likely worth keeping no matter what. The one I had was USA-made and it had a better polish than most Asian mirrors I have seen. I can't believe I let it go. GW
