I have the celestron nexstar focuser motor.  I went from an 8se on celestron mount to an edge 11 on cem120.

 

I can control it via usb in windows 10.  It worked well on the 8se at least.  

 

A few questions:

 

I'm experiencing lag at times where the buttons on the web interface dont work and i have to either unplug it and plug it back in to stop it from moving or cycle the software.

Not sure if its a usb issue or an issue since i'm sending the usb through my cem120 mount (non powered ports on there).

I did apply 1amp of 12v power to the celestron unit, which i thought it needed anyway.

 

Secondary question was on the aux port on the unit, i thought i read a nexstar+ controller could connect directly and manipulate the focuser.  I tested that theory but the controller didnt turn on.

 

Thanks in advance on any of this

Regarding the first question, have you tried a direct USB connection from the focuser to the Windows PC?

 

Regarding your second question, you would only be able to use the NexStar+ hand control to control the focuser when everything is plugged into a Celestron mount (not an iOptron mount).

Yeah this is how i have things connected.  (Its a bit tough at times when the computer is across the way and you are trying to adjust focus from there.  I guess at least a phone app would help)

 

It just seems to timeout randomly.  Actually, the celestronfocuserutility.exe seems to be sucking up 12% causing the cpu to get high in temp.  Its the first i've noticed this.

Hi Mark,

 

If you are interested in reporting the high CPU utilization and timeout and providing direct feedback, you might want to join https://www.teamcelestron.com/ and post a report.

The moderator needs to approve you which takes a couple of business days.  It has been many years since I went through that but I think you will receive an email message with instructions about posting and beta testing in general.

 

I'll email the moderator directly - can you provide the user name you selected for the site?

Ok thanks no problem.  My id there is "markm75"

 

Also, inconclusive but i think a good sign.. last nite i switched the baud rate on the com port for the focuser to 115,200 and i didnt have any lag or even cpu over usage.  Maybe i got lucky, unsure, it was only a brief test, ill try again tonight.
