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

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

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 I wound up with a Mach1 as the 400 was superseded by the larger m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

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

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

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

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

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.

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'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

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

Notice something new with my autoguiding, Maxim DL,APCC pointing model setup upon initial guiding during startup. thereafter it doesn't happen. The DEC axis tracking error grows up to about 2-3 arc-se

Not a goto mount but my mid 90's 600E stepper motor hand controller has an intermittently sticky north button. Any suggestions on how to fix it? Taking the cover off the controller it seems straightfo

With the lousy weather this February I decided to reprocess a couple of images taken back in 2011. Can't get decent skies this week or next according to long term weather outlook. This image was taken
