Hello Jan
Nice to have the new CP4 and new key pad. If you still have the old one, you can check to see if you have a bad connection or broken wire in the key pad cable or maybe a bad connection in the cable plug where it connects to the key pad circuit board.
The keypad has no effect on the operation of the mount. The keypad is normally silent and has no interaction with the mount unless you, the user, sends a command to the mount. If you send a slew command to the mount and the mount runs away, the keypad is not involved at that point. You can unplug it and the mount will continue to run away. This is strictly an internal controller issue where the CP3 is not getting encoder signals from the motor and is thus spurring the motor on in an effort to turn it on.

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... this was very dangerous. I checked all cables, etc., but nothing helped. In any case, I am very glad to have GTOCP4 now.

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.

Unfortunately, I didn't use my mount mostly two years... due to our movement to a new house and building my new observatory.
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.

Thank you,

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...

thank you very much for your tips. That's why I bought a new Y cable too. I will test mount carefully with GTOCP4, new keypad and Y cable and let you know.

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

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

Seb@stro
 

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.

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.
