Does anyone know what mount this is? I know it's a Celestron AZ mount but don't know the model.

That's a Celestron GT mount, but it has a silver bottom cap instead of the normal black.

Many thanks. Do you know if it can be connected to a PC to control remotely? I've tried but unsuccessfully. Wondering if this model is too old to do this.

  Hello ! That's definitely a Celestron GT, looks like mine which is about 8 years old. I've been told that with an aux. splitter, if you plug the HC into one side and a Sky Portal dongle in the other you can control the mount with your android but beyond that I wouldn't know about remote PC. I think it can be done, so stick around and maybe someone else will chime in that's done just that! Good luck!

 

CS, Ralph

Mike Swanson has the Nexstar site, also he can tell you anything you need to know about updates to the HC/MC and he's usually around the halls here answering anything Celestron. Valueable guy for info on anything  Celestron and will help ( as all of us that can!)

It does look like one of the GT models Celestron made special for some retailers (Costco for example).  It is always hard to tell exactly what capabilities these have by just a visual inspection.  If y you can power up, go to MENU, UTILITIES, VERSION and report back what you find, that would help in giving better advice.

 

Regarding external PC control, see this page of my website:

Thanks Mike. Unfortunately when I go to utilities there is no option to select version. Not sure why.

In that case, it is one of the older NexStar GTs, though someone has swapped the tripod with a newer SLT tripod and also looks like they swapped in the dovetail mount that allows you to mount a variety of optical tubes.

 

You can determine which of the older hand controls it has using the instructions at the bottom of this page of my website:

Then one of these two sections of tips applies:

Many thanks Mike, this is very helpful. So it looks like I have a v101.0 hand controller as I can get vega when pressing 6 after choosing 2 star align. So regards the mount, do you know if I can control this mount from a PC? I've tried so far but have been unsuccessful. I've used an RS232 cable with a serial to USB adapter and installed drivers but so far no luck.

The hand controller has the "hamburger" logo, so it's pretty early.

Okay, with v101.0, this tips section applies:

Yes, you can control from a PC, refer to this section of my website for the basics and let us know what specific questions you have:

Hi Mike. I'm resurrecting this old post. It turns out my old mount doesn't allow remote operation. But it has made me want to find out more about when nexstar mounts/handsets started allowing this. Do you know what version of nexstar handset first allowed you to remotely operate a mount from a PC planetarium program via an RS-232 cable? I've seen on your page (https://www.nexstars...m/PCControl.htm) info about what version handset first allowed upgrading firmware but I can't see anything about when the ability of being able to remotely operate the mount this way first came in. Also is this dependant on the mount too? Eg. did older mounts not allow this and if so at what point did they start allowing this? Hope all this makes sense. Cheers, Ben

Hi Ben,

 

All NexStar mounts since the original NexStar 5 (circa 1999) have allowed extended control via an externally connected computer.  (it should be noted the original NexStar 5/8 and original NexStar GT series were a little buggy in this respect)  But, some current external software only supports mounts using the version 4, NexStar+ or StarSense hand controls.  So, you align using the hand control and then you can control GoTos and maybe manual slewing (depends on the software and the mount) from the externally connected computer.

 

That said "remote operation" means different things to different people.  "Full" remote operation is usually accomplished with the NexRemote (older) or CPWI (current) software packages running on a Windows computer.  With NexRemote and CPWI, you perform the alignment in NexRemote/CPWI, not the hand control.  (SkySafari and SkyPortal connected on smartphones/tablets via Celestron WiFi is basically the same but most people would not consider that "full remote" operations, just a replacement for the hand control)  NexRemote requires hand control version 4 or a mount with a PC Port to connect to the mount.  CPWI requires a NexStar+ or StarSense hand control with a USB port, a mount with a USB port (though not the "power only" USB port on the Evolution mount) or Celestron WiFi to connect to the mount.  That is a short description of NexRemote/CPWI - more details are in their specific articles in the yellow box on the right on my "PCControl.htm" page linked above.

 

If you have more questions, it would probably be best to start a new topic here with a descriptive subject.

Hi Mike. Many thanks for your reply, that's very helpful and interesting to learn. Can I ask one last thing? Regards my mount, do I assume then that if I can't connect to it that is must be one of the pre-1999 or pre Nexstar 5 mounts? All drivers are correctly installed, I have followed all the correct procedures with my FTDI cable and also tried a traditional RS-232 with USB to serial adapter. I know the FTDI works because I can connect to my Nexstar SLT with it no problem. Just assume the mount does not have the functionality to allow a PC to connect to it. Or could it be the handset doesn't allow it. The handset is a v101, it was mentioned somewhere only upgradeable handsets can be connected to, maybe this is not upgradeable? There is no literally no response at all.

The NexStar 5 was the first NexStar.  Celestron then mounted an 8" SCT on the same fork and the NexStar 8 was born.  The NexStar GT series came next, followed by the NexStar 11 GPS (and then 8", and 9.25" GPS).

 

Version 101 GT firmware is pretty solid from the external connection perspective but some software does not support it.  You can test your connection using my NexStar Observer List (NSOL) software package:

What other software are you currently trying to use?

Thanks Mike. I tested the mount with your software but I still can't connect to it. I tried all the telescope type options and made sure the mount is aligned first, but still no joy. As a test I connected my other SLT mount using your software and it works fine. I'm scratching my head on this one.

There are still Costco (2nd Gen GTs) out there, Who didn't get two? You have the tripod and can probably score one with a Plus box for $50-60.
