yellow diode raised - motor stall although telescope was precisely balanced
Yes, all this will happen if the motor encoder is disconnected and not working. If new cable fixes this, then that is where the fault is located. If it does not fix the problem, then the motor must be repaired.

Than, I found that keypad's cable black plastic tube completely fell apart, so I bought a new one. When I tried mount two weeks
ago after so long time, it worked as I already described and also yellow diode raised - motor stall although telescope was precisely balanced in both axis. Have to say, that mount was at home all the time when not used.

I also bought a new Y cable, so I will try a new setup probably tomorrow and let you know.

Nice job Kevin!  Other than the short exposures, did you have to do anything special in PI to avoid blowing out the core?  I've been thinking about getting one of those cameras...

Re: AP1100 park position question

I have used Park 4 for several years for exactly the roof height issues that you are evaluating.  This is for a 1100 mount with a 14 CDK scope.  There have been no problems.

I have a PierTech height adjustable pier (http://piertechinc.com/telescope-piers/).  When I need to tinker with equipment, I lower the mount and move it to P3, where it clears the roof. To remove equipment, I loosen the clutches (older style 1100) and rotate/lower the OTA to a separate support table before loosening the dovetail.  I normally leave the pier at almost max height, in order for the roof to clear on opening.

The adjustable piers are actually from another company, but I have forgotten the name.  I think Chris Erickson has these.

If you cannot mount it sideways, ADM makes a unit that turns the bars 90 degrees.  It says Celestron, but it will fit any D-series dovetail

Re: Thanks to AP stuff

I do not know what happened with my older GTOCP3 and/or keypad, but it went crazy because it stared very fast movement of the mount in RA whenever I pressed ANY button, even STOP one.
Usually this is caused by a faulty motor encoder. Therefore a new CP4 and new keypad will not solve the problem. It can also be caused by a broken connection in the Y cable, where one of the encoder wires has become loose. From your description I am guessing that the faulty encoder connection is in the Declination axis.

We can propose a couple of tests that will determine if the cable is bad or the encoder needs replacing.

I'm a Mach2 owner and use it with a MacBook Pro and iPhone and keypad hand controller. The recent upgrades to Sky Safari are a big improvement. I can use Sky Safari Plus to run the mount with my iPhone, even with no computer or keypad controller. The same with my Macbook. I've had occasional dropouts, but they seem to be related to the autolock on the phone, autosleep on the laptop, or conflicts with both the laptop and phone trying to simultaneously communicate to the CP5. When I keep just one device in constant active mode on the CP5 network, all seems fine.

However, there's a glitch in the disconnect commands while using my Macbook Pro with OSX Sierra (not the current OS).

1. when I request to park in its current position, it does, but stays connected.
2. When I request it to go to Park 3, it disconnects in place.
3. When I request it to disconnect at Park 4, it disconnects and slews to Park 3.
4. When I ask it to find Home, it disconnects and and then slews to Park 4.

Despite the command mix-ups, the mount does reconnect and accurately follows commands to any star or object. I've sent this info along the the Sky Safari folks.

Re: AP1100 park position question

Sébastien Doré
 

Shailesh,

What exactly do you mean by "stable"? 

Do you mean in a position where the scopes and CW are in balance on the mount or in a position where you can safely add / remove the components to it ?

In the latter case, the only stable park positions would be Park 2 and 3. Others (park 1, 4 and 5) would require some kind of support under the CW shaft to prevent it from swinging around once the scope side equipments are removed. 

Sébastien


Re: AP1100 park position question

Joe Zeglinski
 

Hi Shailesh,
 
    I see good suggestions about stable, and also safe Park positions for stowing. However, I am somewhat concerned about stowing the telescope at other than Park-2 or Park-3.
 
    I assume there would be an “undo additional strain” on all the various screw attachments on the saddle and OTA, as well as its attached accessories, if the OTA is hanging - straight out to the side. Depending on your observatory’s Latitude, the Park 2&3 positions lessen the overhang loading, as the OTA and the heavy bar sit slightly more OVER the mount, closer to its centre of gravity, and thus somewhat decreases any undo strain on both the OTA various attachments, as well as the counterweight bar threads.
 
    This may be a minor point, but may be worth considering, from a mechanical point of view, assuming  that is a viable option.

I am sure this question is straightforward and I have read it in the manual but I must ask for clarification about stability.

I am considering putting my AP1100 in an observatory. To reduce the height of a potential ROR observatory, is it possible to "stably", stable being the key word, park with CW horizontal and the OTA either on east or west side of the pier?

This will be the normal park resting place always, hence the request for confirmation and stability.

This decision will make a large difference for me in my choices.

Thanks,

Shailesh


Re: AP1100 park position question

Erik Stein
 

As long as you are balanced, it should be stable in any position.


Re: AP1100 park position question

Erik Stein
 


Re: AP1100 park position question

Dale Ghent
 

Park positions 1, 4, or 5 will orient the mount as you wish. Positions 4 or 5 are the suggested park positions and put the telescope on the east side of the pier. Park 1 will put the telescope on the west side. The direction that the telescope points in these positions depends on which hemisphere you are in.

Review this document for the details:

Re: Powering Remote Imaging Systems

we have had zero problems so far with it at remote obs, can't report the same for many other components ;)

Hi Steve,

I use units from OnLogic, specifically the ML100G-51 model. They have a variety of system in industrial and rugged designs. I would keep to i3 or better systems. Celerons, especially N-series Celeron CPUs, don't really have the core count or clock speed when it comes to Windows. OnLogic systems are made in the US, and support is out of the US as well.

In the US and UK, there is SimplyNUC and their Porcoolpine line of passively-cooled units, but a recent update saw an emphasis on Thunderbolt instead of classic USB ports. They're still fine if you need only 1 or 2 USB connections to the box (ie, you have a USB hub).

There are of course a lot of options on Amazon and AliExpress, such as the Kingdel units that Luca mentions, as well as ones from Topton.

Computers are pretty resilient things. You can get fanless systems with SSDs and be completely free of any moving parts that could wear out from long periods of running. It's far better to have a fanless system that is designed to be fanless, than one that relies on a fan for cooling and is in trouble if that fan breaks or gets clogged up with the kind of dust and gunk that often floats around inside observatories.

Something NUC-ish is suitable for almost any observatory's control and acquisition system. You can find small systems with 15W TDP Intel i3 or i5 CPUs that sip power are completely adequate for the task.

For a system I run at SRO and one at home I have Web Power switches for the scripting the powering of equipment on/off through ACP Expert which works great but now years after just leaving the computers on 24/7 forever I wonder about the intelligence of that practice. I do have the computer’s BIOS set to restore to previous state should there be a power loss so that it turns back on and in turn opens the programs I have in the Start Menu which is fine for emergencies but I suspect I wouldn’t want to force stop/start it like that on a regular basis if not necessary.

Re: Interesting Behavior with APCC Pro and Pegasus Astro UPBv2

John Jennings
 

Yes Yes Yes Yes!!!!!!!!!

I've been diagnosing a "mount problem" for 2 weeks. Mach1, APPC Pro, AP155.+Flattener. Perfect round stars on 8 minute unguided exposures repeated one night after a new model. Next week, bad bad bad carrot!!!!!  Tore the mount apart, cleaned all gears,  re-greased, re-meshed, reset backlash on RA  axis and set perfect balance with pinion disengaged (remove gear), generally spent 2 days on mount mechanics.  It absolutely looked like the tracking rate was incorrect.... New medium model, no dice! 

Same Pegasus UPBV2 with latest software.... Did not have this behavior for quite sometime. Not to complain, but Pegaus has had a lot of bugs in their software. I've updated my system 3 times for bugs introduced in new versions. Twice in 24 hours. 

Saw this post and checked the temp in APPC Pro window. Sure enough, 65 degrees C reported. Pegasus reports 65 degrees F in its box.  I would have been searching for another month without this post. Gonna try it tonight with manual temp input. I was so careful about entering the station pressure too. It's always something.
