EQAscom / EQ6-R tracking problem

Recommended Posts

Dear fellow stargazers...

I'm helping a friend with a tracking issue using Eqmod. He has used EQAscom for a number of years with his Celestron CG-5 no problem. Having moved over to the new fancy Skywatcher EQ6-R mount (I'm not jelous... not one bit), he now has a problem with EQAscom. Having chosen PC-Drect mode on the hand-controller, EQAscom connects to the mount and slews perfectly, however when using Stellarium Scope and slewing to an object, the mount does not then continue to track the target (even after pressing the siderial rate button on EQAscom). We have checked EQAscoms 'default siderial rate' and it is as it should be.

It does work however by then going back to the hand-controller setup menu and re-selecting 'Siderial Rate' under tracking, then choosing PC-direct mode again. Then EQAscom/Stellarium Scope works normally with tracking.

Although we have found this temporary fix, it is quite annoying to have to go through this procedure with every session. Has anyone else come across this issue or had no problems using the EQ6-R with EQAscom? Were trying to decipher if it is a compatibility problem with the new mount  (as it is a new kid on the block with different motor drives etc).

 

Thanks in advance for any comments/suggestions

Matt

Have you tried using Stellarium/Stellariumscope without selecting pc-direct on the handset ? Not all planetarium programmes will control the mount if the pc-direct mode is selected.

I would check the following....

When the non tracking condition exists I would put my ear to the mount to see if the tracking motor has indeed stopped and not just going slow.

Do any of the other rates via Ascom work (solar, lunar etc)

Is your power supply for the mount adequate amps wise

I run my EQ5 pro via a 4 or 7 port USB splitter at the mount and run a single USB cable to the laptop. A RS232 to USB convertor does the interface from the splitter to the Synscan hand controller. Sometimes I have to wake up the RS232 link by disconnect and reconnect particularly if I have added another item (like say a focuser) during the session.

Not sure if it would help but have you updated the handset to the latest firmware? Firstly I would  try using cdc and see if this is an issue with stellarium or the handset.

My understanding is that PC direct mode is still a bit of a "may or may not" work solution.  I would try using it direct connection to the mount and ditch the handset, for nothing else at this stage than proving it is the connection mode and not the mount or handset.

Thanks for all the replies.

I've already upgraded to the latest firmware. Still the same problem. It could be the RS-232 link but he never had this problem with the CG-5 mount. It worked every time and that used exactly the same connections. My own EQ6 Pro works fine in PC-Driect mode with StellariumScope and EQAscom. With the EQ6-R it's very hard to hear the motors tracking but when looking at a target through the finder scope after slewing to it, it's definitely not tracking (or tracking extremely slowly) as the target simply moves off the cross-hairs and eventually out of FOV. I know that an EQ direct cable is a solution but don't want to give him the bad news of more expense (and probably the need of buying an xbox controller or the like so that there is still a manual slewing option off screen). I cant remember off hand if he has a spare USB slot either. :\\

Hi folks

I know this is an old thread, but I've been experiencing the same issue with my new eq6r... It doesn't track the object properly... I choose the EQMOD ASCOM HEQ5/EQ6 driver in CdC and PHD (also tried via POTH) using the EQDir cable but with no success. However, doing the same via the hand controller/Pc Direct Mode, the traking seems to improve and I'm able to guide 2-4 minutes... That's weird because with the same setup I can guide twice with my heq5...

Did you find any solution or clue about the root cause?

Thanks

      Hi All
      Has anybody else had this problem?
      I use a single, ageing laptop (HP620 8Gb RAM) running Windows 7 Pro 64bit to control my imaging setup using the following software;
      Cartes du Ciel and EQMOD to control EQ5 Pro mount via EQDIRECT cable connected via powered USB Hub
      BackyardEOS to capture images from Canon 450D via same USB powered hub
      PHD2 for guiding using GP-CAM 130C and EQMOD pulse guiding
      What confuses me is that some evenings everything works absolutely fine.  Another evening, using exactly the same hardware, software and even connections (ie I always plug the leads into the same ports) the system will be working fine but then suddenly fail.  The failure affects EQMOD indicating a timeout or port not available issue and the Canon 450D also 'locks' requiring a restart of the camera and BackyardEOS.
      I have run USBTree during such a failure and it is showing that the EQDIRECT cable (ie serial converter) is still connected to COM4 (which is correct) and the Canon 450D is also still connected.  I basically have to ensure that all the software is closed and any associated services also stopped.  Of course, the scope is now pointing away from its home position so I have to move it manually back to 'home' before starting again.
      My thoughts are that there could be a number of issues;
      1. Use of a USB hub
      2. A dodgy EQDIRECT cable
      3. USB cables too long (ie about 5m)
      4. Windows is turning off a connection (I have set the power management for each USB port to 'off')
      5. Canon 450D somehow 'freezing'

      When using this laptop, I turn off the Wifi and Anti Virus and Automatic Updates are also off.
      It just baffles me that sometimes this system works flawlessly for hours and yet other nights it keeps failing.
      Any suggestions gratefully received.
      Thanks for looking.

      I am at a complete loss to understand why eqmod was not syncing on CdC last night. I have had a look at this video, I had the star centred on the screen [3m33s], I pressed sync on CdC, I got the dialog box [3m39s], I clicked 'yes' and NOTHING happened: the white circle stayed where it was, no sync points were added to EQMOD, zilch!
      I can get round most problems, but this really one stymies my GOTOs and, therefore, my imaging process.
      I have been unable to find anything in the EQMOD documentation that deals with such an error and a search on here has turned up no help (but that always depends on the words put into the search!). I checked all the obvious things (location, date/time, etc - but why any of these should stop sync working is beyond me). It's all running on Windoze 10.
      Any suggestions on why this should have stopped working and (more importantly) how I might get it working?
      Thanks.

      Setting up all the software on my win10 laptop and getting things to talk to one another is a nightmare.
      I'm starting a new thread, so I can post all the problems I am having, one at a time, so issues don't get confused. This will also hopefully help anyone coming to similar situations later, as the problems and answers will not be interlaced.
      First issue: APT does not detect ZWO camera.
      I have got the camera (ZWO) drivers installed and sharpcap can see it and will connect to it properly. However, when I try to connect the camera in APT, the only CCD options it gives me are SBIG (which it isn't), QSI (which it isn't) and ASCOM. Now it shouldn't need to use an ascom driver, because the proper driver is installed, but I give it a go anyway, and this just offers me 2 simulators and 3 QHY cameras (I have one qhy driver installed for the guidecam .... I'll get to that later!). I have disconnected both the filterwheel and guide camera from the camera hub, so they cannot be interefering with the process.
      I am at a total loss ... any suggestions?
      Thanks.

      Hi guys,
      I been googling a lot and was not able to find a solution how to connect EQMOD to the Mount via SW Wifi Dongle...
      it looks like EQMOD needs COM Port to be used....
      I do remember there was some kind of "Virtual Com port bridge to Wifi"app back in Win98 days... But I cannot find anything similar for Win10.
      I want to test EQMOD auto-guiding via WIFI, - I know, it's not reliable, but I want to try
      as I have Skywatcher wifi dongle and my USB to Serial (RS-232) Converter Cable is wayyyy too short to keep my PC (and me) in warm.
      I am able to connect with SynScanPro app to Wifi Dongle and even sync it with Stellarium nicely... 
      Only Auto-guiding missing...
      Any ideas?

      I’ve been having issues with platesolving using Platesolve2 and my Ioptron IEQ30PRO Mount, I’m connecting using the Ioptron Commander Ascom driver. I’m using Maxim DL5 to locate and image via the Planetarium section. When the Maxim platesolving fails, especially when I’ve just started in a new location, I need to use Platesolve2, which is installed as an add on. Unfortunately I can never sync once it’s finished platesolving as the telescope disconnects at some point in the process. I only use the above setup at Star parties.
      At home I have an observatory with Eqmod running an eq6. I don’t have any problem using  Platesolve2 in a Maxim.
      I was wondering if I should be connecting using POTH in between Maxim and the telescope driver. I don’t generally connect a planetarium programme now I use platesolving but I want to use The Sky6 to help with camera orientation in the future. As I understand it Eqmod will act as a hub allowing this but Ioptron Commander won’t. This may be why I have issues when using my Ioptron Mount.
      Can someone confirm that I’ve understood the process correctly, please?
      Anne
