Dear Don, We usually try to provide an upgrade path for various features as much as we can. In the case of home and limits, we are about to release a new version of APCC that has an excellent home

The mach1 does not need a deep cycle marine battery. Any 12 volt battery will work, the amp hour rating depends on how long you wish to operate before recharging the battery. During sidereal tracking

Hi Ray, I am really thankful for your help and I hope to be able to repay my debits. I have uploaded a screen dump "from Mount". You are probably correct in suggesting tnhat the calibration has not

Chiming in late, I would and will always go with AP. The customer support is some of the best in the business. -- GregoryGig Harbor, WA.

Thanks! Flavio

Hi Vince, The curve with PEM enabled looks like it was overcorrected which could happen if the image scale was wrong. To prevent this from happening you should always run the PEMPro's Calibration

Hi Gregory, Thanks! I try to make the videos as short as possible so they require a minimal amount of time to watch. Everything seems to go smoothly because I usually have everything setup and

Hi Ray, last night was clear so I was able to run Pempro with the PEM enabled. The result is in the folder "vince" and the file is called "PEM enabled". Thank you for you advise and support. Vince

Ray, I've been watching the videos in your library and just wanted to say thank you for posting them. Although they move fast, they are very helpful. I just wished I could execute

Back in early March I queried Marj about whether an upgrade would be offered for the 900/1200 series mounts. She said no. Not surprising since to do so would negate one of the most powerful

Christopher, Interesting observations. I've completely given up on CN -- notonly trolls, but intentional mis-information and dis-information being supportedby management -- Astronomics. Inever

I'vesuccessfully run my Mach1 off a 22 Ah JumpStarter battery. But when I dothat, I also slow down its maximum slew speed. Woody

That was what I was thinking. I wonder if it could even been something as simple as external magnetic switches that define the home position. Cheesy but maybe it would do the trick. Stuart -- Stuart

I wouldn't be surprised if there weren't absolute encoder kits eitherfrom AP or a third party that come available for the 900/1200/Mach1 mounts someday. For now the CP4 digital input port for future

Christopher, Dean, hope you don't mind me piling on here. I'm like Dean, running remotely. Can't see a ton of use for Wireless or USB vs. Serial that I have now. CP2 btw. Christopher, I'm confused by

Just my opinion but the absolute encoder input combined with the digital input for limit switches and such is a big deal. Not to mention the ARM Cortex M3 processor. The CP4 has horsepower to burn

Thanks Chris, a little more refinement: The DC-DC converters usually don't use an inversion stage, although they will if galvanic isolation is required. If so, it is really an inverter with a

CN isn't a joke but it is a different kind of communicationsmedium. Unfortunately web forums like CN are going strong and growingwhile Yahoo groups are rather stagnant. Part of the reason is that
