Need help ASCOM for Stellarium Telescope Control

Recommended Posts

Hello, i am new to this forum, i made my account here because i need help.

So few weeks ago i ordered a USB to Serial cable to be able to Control my Telescope with my computer using stellarium.

It arrived today.

So i made my Star Alignment, then i plugged the cable to my Telescope and Computer, i installed the Cable driver and ASCOM Platform + ASCOM Celestron Driver.

I started DriverConnect.exe and put the Celestron Driver i downloaded, and did the properties informations ( had to tick on "Advanced Setup" and "Show All COM Ports" ) and i put "COM8" on "COM Port", then i pressed "OK" and then "Connect"

Result:

Create              Creating device
Connected           Connecting to device
Error               System.Exception: Connect to COM1 failed, no Celestron scope detected
   to System.Dynamic.ComRuntimeHelpers.CheckThrowException(Int32 hresult, ExcepInfo& excepInfo, UInt32 argErr, String message)

"Connect to COM1 failed, no Celestron scope detected"

In Stellarium i set-up everything, the plug-in and restarted the app, then added my telescope  and i says it's "connected" but i can't find my telescope.

 

Telescope:
Celestron NexStar 127SLT

The Cable i bought:

https://www.amazon.com/Telescope-CP2102-Adapter-Control-Console/dp/B077G37VL1/

PC Specs:

Windows 10 Pro, GTX 970, 8GB Ram(DDR4), i7 6700 3.4Ghz

 

Looking forward for your help, thanks in advance,

dragorom7.

Hello and welcome to SGL.

Thoughts
1. You selected com 8 for the usb-serial  adapter but com 1 is shown in the Celestron setup window. EQ N is also selected as track mode, this should be alt az for the SLT.
2. The Meade cable might not work with a Celestron mount.
3. If the Celestron SLT mount works like the Skywatcher AZ -GOTO then you need to connect the mount to the computer via the handset using the correct cable, not directly.
4. The ASCOM platform and ASCOM mount drivers aren't required to control the mount through Stellarium, Stellarium has its own mount drivers.
5, If you control the mount through ASCOM you also need Stellariumscope  to communicate between Stellarium and ASCOM.

1. Sorry i just changed my COM8 to COM1 on windows device manager, this is my bad. Also i changed EQ N to ALT-AZ.

2. I was able to plug the cable on my telescope bottom of hand controler and it fits perfectly, but though it can be the issue if it's the wrong cable, but if it is, which cable do you recommend me?

3. I connected it to the hand controller bottom port where it's written "NXS"

4. It didn't work with it's own drivers so i did some search and got told i must have ASCOM

5. I have Stellariumscope installed, and it does the same error as ASCOM: " Connect to COM1 failed, no Celestron scope detected" in an box

 

Thank you for your help and answers, you are very helpful, i hope i will be able to fix it.

I think i bought the wrong cable, it says on amazon that it's RJ-10 and the real celestron one is RJ-11

      I have the aforementioned telescope but not used it in several years. It's just been sat, quietly out of the way in a small cupboard (dry, dark, nothing amazing) but not stored in it's box as perhaps it could have been. Nonetheless, I went to take it out as a friend had asked me to take it to his for an evening's viewing pleasure. I tried the batteries I'd just bought (16xrechargables) but was unable to get any signs of life. Between myself and a friend who's somewhat more conversant with electricity than myself, we discovered so far that there's no signs anywhere of life from it - but we're not (as yet) sure whether it's a poor connection from the battery compartment or the switch. We do know the batteries are good. 
      Any advice on narrowing down causes, please?

      I’ve been using my 8’ Edge HD on an Evolution mount for a couple of years now and I added a wedge to it a few months back. Using SkyPortal with StarSense I’ve never really had any major issues getting it aligned. 
       
      Last night I was setting up to photograph Mars and went through my normal procedure. StarSense took its images but, after confirming success with the third plate, instead of just winding up a bit and parking it proceeded to pitch the ota towards the north well below the horizon.
       
      Fortunately nothing snagged. I skipped the ASPA and instructed it to goto Mars and was surprised to find it was spot on (better than usual actually).
       
      Anyone any ideas why it took that nose dive? Thanks.

      Hi,
      Now, I know that Cubble likes to keep fit. I try to keep all of my telescopes healthy and feed them only the best planets and DSOs. 
      But - why is that Cubble just LOVES to go all around the houses on some of his GOTOs?! Talk about taking the long way home!!!  I could have sworn that I had 'Cordwrap' set to 'Off'............. 
      I have set Cubs up with a totally cordfree / wire free system and therefore find this going 340 degrees around to an object that is 10 degrees away incredibly annoying and time wasting.  
      Well, I think I may have found the answer today. Some of you may already know this but for those that don't, I hope it helps relieve some of your frustration. 
      What I disovered is that the Star Sense hand controller resets the Cordwrap setting (MENU>>>TELESCOPE>>>CORDWRAP) back to 'ON' each time a new alignment is completed. So, one can spend time seemingly making sure that it is set to 'OFF' (if that's the setting you want, of course) only to find that once you have completed an alignment, the hand controller defaults the Cordwrap setting back to 'ON'.
      So, if you don't want or need Cordwrap set to 'ON', make sure you change the setting after completing each new alignment.

      What telescope brand would you choose?
      Reply below for your favourite telescope brand. It would be really helpful to know which brand to buy.
      Celestron, Meade, Orion, Skywatcher  etc.  
      Thank you for viewing

      Hello,
      Does anyone know if I should upgrade my telescope? I have a Celestron Nextar 127slt and I've been using it for a few years now. I want to see more detail on Jupiter, Saturn and Mars.
      Does anyone have any suggestions from Celestron?
      Kind Regards
