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.
I know it may be a bit of a long shot but I'm looking to buy a HEQ5 Pro mount or an NEQ6 Pro or something similar. Preferably belt driven but not necessary as can happily modify it. Please let me know if you have anything! Thanks.
Please find for sale my SkyWatcher 250 Reflector and NEQ6 SynScan mount.
The reflector has of course been used and shows sign of use on the outside of the tube but the mirrors show little sign of wear or tear apart from a few dust specks. As you can see from the photos the Scope is in very good condition and all viewings are welcome.
The NEQ6 mount powers up but refuses to move. This may be just an update to the handset or maybe the gears need a touch of TLC due to itself being sat doing nothing for so long. The tripod is missing the locking pin that pulls the plate up against the legs but this will be reflected in the price.
i would like to offer this to the SGL community as I know it will go to someone who will appreciate the kit and do so much more with it than I’ve been able to.
Given the fact I haven’t used this kit for a few years now and I’m also moving house, I know longer have the time or room for it so this is the only reason for sale.
*** Update 26/1/2020
I have purchased a new support shaft for the tripod and I have also got the NEQ6 moving so the motors seem to be absolutely fine, please see latest video attached of the NEQ6 powered up and moving.
Skywatcher 250 - £200
NEQ6 - £450
Collection only from Walsall/West Midlands
Please don’t hesitate to contact me if you have any questions and I will do my best to answer them.
Wishing you all clear skies wherever you are
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?
