I having a problem with my new Mach 2 which was just installed yesterday. I'm using the Ethernet connection, APCC and TSX. Initialization and connection to TSX went fine. There are absolutely no obstr

If one were to ship a 1600, first generation back to AP, would you folks be able to do an absolute encoder install on it? Time needed for that? Moving from SE Arizona to very rural and dark NM. Observ

I think this question is for Ray Gralak; I've gotten very comfortable with APPM and use it every time I set up for imaging. I only have a partial view of the sky and I set up runs of between 49 and 87

Here is the question, some nights here are quite warm, about 20º C, resulting in a large number of useless frames, other nights are colder and there the modeling I have works perfectly. And I was wond

Are these sold in a set separately? I could use a spare set if so. If anyone knows the part number I can look up that would be helpful. Otherwise I can call AP on Monday.

Does AP have a Polemaster adapter for my Mach2? David C. Finch

Hello Astronuts, To clear up any confusion about mount encoders, both Mach2 and 1100/1600 use the same Renishaw RESA high resolution encoders. The main difference is that the ring diameter of the 1100

Hi gang, I am the proud owner of a brand new (well 2 weeks) Mach2 and tried to do my first APPM model tonight. I'm having problems with the dome control and hope someone can point in the right directi

Howdy, First off, love the MACH2GTO-L. What an amazing piece of engineering and precision machining. Kudos to your engineers and machinists. The manual discusses the home position as, “... a very spec

I will put in my 2 cents on this. Back in the day I put my name on the list for a 400 as I wanted a smaller mount to go with the 600E. I wound up with a Mach1 as the 400 was superseded by the larger m

I was following instructions to update the CP4 firmware through the USB. I opened the utility and selected the com port of the mount and proceeded to load the zip file. Pt.2 loaded fine, then instruct

Hi everyone, I have an 1100GTO on order, so I'm trying to decide what to do about a portable pier. I am wondering if anyone can share experiences and/or insight regarding the AP Portable Pier. My main

I am ordering the 1100 with extended temp encoders. I currently use the 900 on my Rob Miller TRI36M tripod that has the FSA top which is currently attached to the 900RPA which mates to the 900. Is the

Wondering how the updated keypad software is doing and if there is a new projected release time. John

Hi folks, I was lucky enough to be notified recently I’m going to be the proud father of an 1100GTO mount. I have read through the GTOCP4 Operating Instructions as I plan on how to connect the mount t

Here's a little lesson learned tidbit that I just discovered on my 1100 mount: I have been noticing lately when setting up the mount with my 180 EDT that there is some play in the dec. axis. I thought

I have a question about when to use the Clutch Knobs vs. the Gearbox Release Levers. I currently have a Mach1 in my observatory and when balancing or moving the scope to different park positions I typ

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

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 softwa
