Yeah the 1100 is really well designed. If a bonehead like me can use it for 5 years and not have it be smoldering pile of aluminum -- anyone can use it.😂 Speaking of design, there is a sentiment

There are no Delrin plugs. You can tighten to your heart's content. Use hex keys to really lock them up if you wish, but make sure that your scope doesn't run into something since the clutches won't

One more thing, modern A-P mounts no longer use Delrin plugs. Read the operating manual about tightening knobs. Peter

I use the long side of the Allen wrench into the knobs and tighten the short side with my fingers. This way it’s more difficult to over tighten. Peter

Hand tight works for me. Can always get it a little baby nudge with a hex if you really care that much.

On an AP1100 can I tighten the clutch with hex keys or just hand tighten? Will overtightening damage Delrin plugs? Shailesh

I no longer use mounts without encoders. 🤣 😂 😄

This is only with an encoder mount. Non-encoder mounts will need to be re-calibrated if you move it manually. Rolando

Very cool. I always thought I was making the mount lost if I released the lever to make a small balance adjustment. Now I know it's not lost at all. I did not know that it needs to be powered off.

Rolando, Unfortunately mine is the first run mount so I don't have the gearbox lever but I really love the mount!!!! But I understand your comments. Thanks, Peter

Yes, the mount would know it was in position 5, so when you apply power and sent it home, it would go to position 3. Release the lever only when the mount is powered off, otherwise the encoder will

This is good to know! So if I released the mount with the lever, and moved it from Park 3 position to Part 5 position, and locked the lever, and told the mount to home (lets say home == park 3) then

Read carefully what I wrote. You must leave the clutches locked. You cannot move the mount via the clutches. You can move the mount by unlocking the gearbox lever. The encoders will follow the motion

Hi Rolando, You said: "If you lose the mount thru an errant recal or sync, a simple "Home" will re-establish the correct co-ordinates." I have A-P1100GTO-AE and I was not aware of the "Home" feature.

Can't answer that without knowing the application. Rolando

Roland listening to all the explanations etc. if money wasn’t an obstacle which mount would be the best? Meeting low temperature remote and any other general pain, the newest 1600, Mach 2, the 1100

By the way, besides Ray Gralack, our software engineering staff includes Mike, Liam, Howard and Charles. 5 very knowledgeable persons, all working together on various parts of the mount control

Hi, Your posts have been quite accurate, so not to worry. And thanks for helping out on that forum. Rolando

I have posted a fair amount of stuff to that thread regarding encoder operation on Astro-Physics mounts, including the AP1100/AP1600 and the Mach2. I hope that it’s been accurate – and I am

This post has a bit of misinformation about encoders on our 1100/1600 mounts, and I need to clarify how the encoders actually work: Sounds way too complicated to me. When I even suspect that one of my
