If you are asking the mount where it is pointing, then nothing will change in the mount controller. However, if one of your external programs is sending to the mount either a time change or date or location change, that can place the meridian line in a wrong location.
 
I'm betting that you have set the ASCOM driver in conjunction with the dome control program to continually update the mount's time instead of using the keypad's original initialized time. Controlling the mount's parameters of time, date, location should only be done by one program (either the one in the keypad or the one in your computer). Bouncing these vital data numbers back and forth can have bad consequences, especially when parking at the meridian (Park1) or operating near the meridian.
 
When you talk to George tomorrow he can go over all your settings with you and recommend ways to do this properly. If it were me, I would control the mount with a planetarium program and the dome from that same program. Instead of getting the information to move the dome from the mount, use the information from the planetarium program. Programs like TheSky work perfectly with the mount and do not cause bogus data to be sent. When connected to the mount, this planetarium program always knows where the scope is pointing, does not send the scope underneath the mount and can be used to point your dome opening to the same place.

Hmmm. Curious. This would explain why what had always worked before now does not. But I am not sure what, if any, commands Digital Dome Works sends back to the mount. It appears to only receive commands from ASCOM, mount position, so it can slave the dome. I will research this, and try the test without DDW online...  CG

Any idea what the upgrade price will be for the new type "gear mesh" housing? I received the 1100 mount on Nov. 10-15 when you had the special pricing on your mounts.

Will they be ready anytime soon :)

I have a AP 900 GTO3 mount and recently upgraded to a AP 1100 GTO 4 mount so thought it would be useful to others here as to my impressions between the two and whether the upgrade gave me much.

 

-The relocation of the Azimuth knobs to the back of the mount was a HUGE improvement. With my 6" APO refractor it was always a PITA to do the polar alignment..

-The internal wiring capability is a big improvement although it does take a bit of additional time to route those many cables....but it is nice not to have all those wires dangling and chancing a snag.

-Having a separator to keep those wires out of the viewing path of my RAPAS is nice. Also I can now see through the bore no matter which way the DEC axis is turned.

-Clutches are much improved...no longer have to worry about squashing the clutch felts.

-One of my favorite upgrades is the ability to easily disengage the worm/ring gear mesh so the mount is free. This allows much more precise balancing of each axis. I was concerned that if I disengaged that it would cause my PEC to go out of sync. But AP said no problem.

-The setup for adjusting for different latitudes is great and allows me to move the RA axis all the way down for storage making the mount more compact for storage.

-Has a bubble level (Yeah!)

-High quality of workmanship on previous mounts continues with new mount.

 

-The new GTO 4 box upgrades are wonderful. Having a choice of USB, Ethernet, or Wireless connection is great.  I have been using the wireless connection to my Samsung Android tablet running Sky Safari Pro5 and it works perfect. The wireless signal is very strong so no issue connecting and staying connected. Before wireless was not possible with most Android tablets as they didn't support Ad Hoc wireless which was needed for the Sky Fi unit so had to use the SkyBT version which was just so-so and not to robust.

-I am using my old hand controller from my previous GTO 3 box and no glitches although it has been updated to the latest firmware by free download from AP web site. I run everything wireless on my setup into my house about 25' away and through a wall. Focuser, planetarium program, are wireless. Only cable to the house  is an active USB 65' long cable to the SBIG STL 6303e camera with slave autoguider.

 

-Polar alignment when I travel to remote sites is even more of a breeze with the RAPAS now. I can polar align the mount in about 3 minutes. This was easy with the old 900 mount but now I don't have to deal with getting a clear tunnel through the mount DEC axis.

 

OK I guess there has to be a con somewhere. The only one thus far is that the telescope sits a bit higher above the central axis which means you will need your counter weight moved out farther or add additional weight to counterbalance. But that is not a big deal for me.

 

So in conclusion...for those sitting on the bench trying to decide if the upgrade is worth it....yeah it is in many substantial ways. This is not just a tiny cosmetic upgrade but a really well thought out engineered upgrade.

Re: Slewing towards pier: what am I doing wrong this time?

Roland Christen
 

Upon thinking further about your problem I realized that you are also controlling the mount with another external program from a 3rd party (Dome Control?). This may be the source of bogus commands that changes data inside the mount servo control and causes improper slews. I would run the same exact tests that you ran, but have no other program attached to the mount except the keypad. Then if the same issue occurs, we can isolate it to one program, the one in the keypad.
 
You can also look at log files to see if any strange commands were sent from your computer to the mount in your run this afternoon.

Missing information such as "Parked it last night" where?
Slewed to which star at what time?

Re: 900 vs. 1100 mount review

Bravo Bob !
 
    This was a welcome and succinct summary of the differences affecting the user enjoyment of these mounts. Could have added the load carrying difference.  Almost makes me want to exchange my beloved ... AP-900/1200 mounts.
 
*******
    However, one thing I really wish AP had “finally” done for the new CP4, was to provide suitable, preferably screw-on,  “plastic protection caps” for all the connectors – especially the large ones “unused” by most of us. I hate dew dripping down into the open (never used) sockets such as the ENCODER and AUX -  pins getting fouled or oxidized, or their becoming bug nests. Guess I will have to use electrical tape on the other unused ports (e.g. USB, Ethernet, and AUTO GUIDER relay port) ... or plug in a dummy cut-off plug as a kludged filler – since I will continue to just use RS-232, for now.
 
    Such caps can’t be very expensive ... until users have to buy them in large “minimum order” quantity, and also adding the shipping charges for something so trivial, and more easily affordable (considering the CP4 price) -  by including the first set of caps with each CP4 shipment.
 
    At least we still get ONE anti-static RS_232 port  protector cap, as has been done in the past.
Protective terminal caps would make it look tidier and more professional.

I notice that you are using a Kendrick power distribution module. Do you have multiple items plugged into the same power source with the mount?

 

Please note that we recommend that the mount have a dedicated power supply. Dew heaters and other accessories tend to pull a lot of power as they cycle, which can cause significant drops in power. If that happens, the keypad will not have enough voltage and may reset.

Subject: [ap-gto] AP Mach 1 with GTO 4 and a Hand Controller

 

 

Hi, I have a relatively new AP Mach 1 with GTO4 and a handset.  While observing visually a couple of nights ago, I suddenly lost power to the handset.  Upon investigation, the following was found:

 

Battery power was still at full, battery booster was putting out 13.5 volts to the Kenderick power distribution module. 

The Kendrick was still powered up and working normally, including the AP power socket going to the mount GTO 4 box. 

The GTO 4 was still powered up.

The mount was still tracking. 

 

I rebooted the power quickly, off at the Kendrick, back on in about 5 seconds, and everything came back up normally, including tracking.  When I looked at the handset, it had come back up on the normal object tracking screen, and knew where it was...

 

Any idea what happened, and how to fix it?

 

Thanks in advance,

 

Bill Taylor

Re: ASCOM/ACP interface set offline...

Programs?  Well, just Google browser in the background, and Digital Dome Works, plus Windows. 

I am using a USB connection from the CP4 to a Icron Ethernet "hub" then direct USB back into my computer. This has worked very well with the AP CP4 and my SBIG STT-8300/FW8G/Atlas focuser. So if that is an issue, it doesn't seem to manifest in any other the other systems. 

Curiously, my tests of the dome slave setup today running for about seven hours did not produce the same fault, so I guess it is random now....  I really expected that it would happen again. I am doing another test run tomorrow to try and capture another error. CG

Certainly sounds like you lost communications with the driver. What other programs are being used and how do you connect to the scope, direct serial port connection or USB to Serial convertor….

Hello again!

 

I tried to find the proper tech forum for this ACSCOM AP v2 5.09.01 error, and all signs point here.  So here goes. (If there is a better forum, please direct me there!). Maybe this is purely an ASCOM or Digital Dome Works problem rather than with the AP V2 driver. Don't know yet...

 

I am currently using Technical Innovations/Homedome Digital Dome Works (v.5.2) to slave my dome rotation to my AP900 mount. Some hiccups notwithstanding, so far so good. However, I have encountered a problem with DDW and the interface it uses to communicate with the mount, ASCOM Astrophysics V2 5.09.01. Here's what happens...

 

When I initiate DDW, it invokes the AP V2 5.09.01 driver window. All the fields populate (I presume) with data from the mount. All the buttons on the AP driver (NSEW, etc) work fine. I can slave the dome to anywhere the mount is slewed (via keypad) to. All is good. 

 

However, after consistently slaving the scope for, say, four or five hours, I get an error in DDW:

 

ASCOM/.ACP interface set offline

and DDW reports operation failed, which I think means DDW could not slave the dome because it no longer is receiving a data stream from the mount. Further, the RA and DEC fields of the AP V2 drive are rendered blank, although all other fields are present. The TIME, however, seems to "freeze" at the moment the failure occurs. 

 

The only way to recover from this is to end and restart DDW, thus reinvoking the AP V2 driver. 

 

Technical Innovations is looking into this as I write, but I thought I'd post it here, too. I Googled the error and didn't come up with anything similar. For some reason, somewhere along the line, the handshake between ASCOM and DDW is being broken. There is no timeout as far as I know. 



If there is a place in the ASCOM driver set to check for errors, I am not sure where they would be. Everything is up to date also.



Any suggestions would be greatly appreciated!

Chris,

 

Are you using ACP in the mix? That’s what it looks like with ASCOM/.ACP interface set offline. If I saw this and was using ACP I would make sure ACP is still connected to the telescope driver. Just a guess.
