connection to com port failed, cant connect to telescope

[cfeastside]

using BYE v 3.2.2 RC1(Trial version) and trying to connect to celestron evolution mount with the following error:

1. 10:13:19  Connect to COM3 failed, no Celestron scope detected
2. 10:13:19  ASCOM Telescope disconnected (or unable to connect).
3. 10:13:19  Make sure the correct COM port is assigned to your device.

i have the mount connected to the laptop via usb and to the starsense hand controller.  I get this error even if the mount is connected via wifi. 

 

i can connect to the mount via the usb connection no problem.  any ideas how to connect to the telescope?  Oh, I'm running Parallels and Win 10 on a macbookpro.  Thanks!

figured it out.  i had installed CPWI first before the ASCOM DRIVERS, apparently thats bad.  i uninstalled CPWI and then reinstalled it.  launched BYE and selected CPWI as the ASCOM telescope chooser window.  success!

This is not a BYE issue. It will happen with any ASCOM client application, since they all use the Celestron Telescope Driver to manage the communications.

If you uncheck "Show All COM Ports", does COM3 disappear from the COM Port dropdown list? If so, then the Celestron Telescope Driver is not able to communicate with the mount. 

The most likely reasons for this are 1) you selected the wrong COM port or 2) Parallels is not configured to expose the USB connections to Windows.

The most likely reasons for this are 1) you selected the wrong COM port where would this selection take place? or 2) Parallels is not configured to expose the USB connections to Windows.  

thank you for your response!  not too versed in ascom or windows really so this is a bit of a head scratcher.  camera connects no problem.  so if this doesn't connect not really a big deal i can still slew the telescope via CPWI.  would just be nice haha.

Yes,

CPWI will only install the ASCOM telescope driver if the ASCOM Platform is already installed.

Thanks for letting us know.

I have an older Celestron Nexstar 8SE scope (2003)with a controller that stopped working. Couldn’t find an original replacement, so bought the Nexstar+ in 2020, which looked as if it would work, but would not control the scope. Any suggestions?

This is not the place to ask that question. You should talk to Celestron Support.

Also, in the future please start a new thread when asking a question.
