Now I’ve managed to sort out control of my EQ6-R Pro using Stellarium via EQASCOM, I’m working my way through the other equipment I want to control from my Windows 7 laptop.
I’m stuck trying to get my Celestron focuser to be recognised. This is what I’ve done so far:
Downloaded the Celestron Focuser Utility Program (.exe file) from here: https://www.celestron.com/pages/manuals-software Also downloaded the December 2019 USB ASCOM driver set up from above. I ran the ASCOM driver set up and restarted the laptop. Connected focuser direct to laptop via USB. The focuser’s power light shows red and in Windows control panel it recognises the device as ‘Celestron Focuser’ but indicates no driver present. Ran the Celestron focuser utility program hoping it would connect and install the right driver so I could calibrate, but it can’t detect the focuser at all. Finally, ran APT to see if I could connect by choosing the ASCOM driver under ‘Gear’ but this doesn’t work either. Stuck now. I’m guessing I need to somehow ‘tell’ Windows where the driver is...?
Any thoughts? Thanks everyone
EDIT: I have previously had this focuser working correctly both with StarSense handset and via ASCOM (Celestron unified driver) through the aux on my old Evolution mount. However, now I’ve changed to a Sky-Watcher mount, I need it to function direct through USB.

I’ve just bought a Skywatcher EQ6-R Pro. I’m trying to drive it from Stellarium using EQMOD but I’m running into a problem I haven’t the experience to solve.
This is my set up:
Windows 7 Laptop > 10m active USB 3.0 cable > 4 port powered Atolla USB 3.0 hub > Lynx Astro EQMOD cable > Mount (plugged directly into hand control socket)
When I first connected the mount to the laptop (a 2015 Dell Inspiron) Windows 7 searched for a serial/USB driver and installed it on COM 8 (according to Device Manager).
In Stellarium I created a profile for the mount but it wouldn’t autodetect the COM port. So I manually set it to 8.
When I try to connect to the mount it sits for a while and then tells me the connection has timed out.
Anyone have any suggestions as to where I should start to try and get the connection sorted please? Thanks.
am posting this in case it helps anyone who has suffered the same problem as myself.
In a nutshell: Own a Skywatcher Gti mount for some time now and used with some success, also purchased some time ago Skysafari and wanted to use both, with a problem much reported on the web and so much information out there that it can get a bit confusing and certainly in my case frustrating, after all just want stuff to work!
After much experimenting and help from other postings this is what happens when you fire up the Gti.
The mount generates its own wireless network and becomes the gateway, its IP address is always 192.168.4.1 you see this when making a connection with the Synscan app/program, its very similar to a normal router that serves you the Internet. Any device that then connects to this network then gets an assigned address one up from this, i.e. 192.168.4.2, .3, etc. However if you run the Safari app and go in to settings you will find it has also been allocated an address which is one up from the device you are using. In my case my Ipad was connected to the wireless network and had been given the address of 192.168.4.3. but when I checked the IP address in the settings page of SkySafari it was 192.168.4.4 !
If you accept this you get the error that the app cannot join the wireless network check your settings etc. If you now manually change that address to the same as the device running the Synscan app in my case .2 it should connect and work. However there is a caveat to this, I tried using an Iphone 4 and an old Ipad and they would not work together no matter what. I got the other error message that I had joined the network but the mount did not recognise the device type I had selected (Skywatcher Synscan Alt Az GoTo) and no amount of changing things would solve it. To get around this I used my trusty Win 7 laptop to run the Synscan program and things worked perfectly so it can be done don't give up!
Sorry this is so long but I hope it helps someone out there. So to round off when you fire up the mount it becomes address no 1, any physical device gets the next address 2, any software running on the that device gets the next address 3. When you fire up SkySafari it must have the same address as the one that the SynScan app has got and this can e changed in SkySafari settings. None of this makes any sense to me as I thought software couldn't act in that way but there you are. I hope I have got this right feel free to contact me if things don't work
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?
