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.
Starting my 1st IOT project. Since i've been an astrophotographer with no permanent setup, it makes sense to reduce the physical footprint (and the weight) of as many equipment as possible, as well as to do better cable management. I am soon going to start using Astroberry Pi server, an Ubuntu based suite for Astrophotography. Just purchased a Raspberry Pi 3B along with a 3.5" display for that. Lets see how it goes.
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?
I continue to get my Star Adventure to perform better.
One very big problem if you have a camera that you can not tilt the display at, no tiltable display. I have the Canon 6D. It's almost impossible to see the display and do settings when the camera aim upwards to the zenith. I have until now used a very tall tripod, but that is something very big and not so friendly when travel.
Instead of buying a new camera I now test to use an app in my smart phone and used that to see the display in live view from the camera.
I have written a tutorial in an early stage of how I do that:
I will correct and add more information when I get more experience from this.
I'm sure most of you alreday have done this, my concern is, how hot will the camera be. I have bad experience from this from earlier test with live view.

I have searched SGL for a tutorial incase this has been covered so forgive me if it has. I've also searched the web in general and couldn't find a full tutorial to do this, so i have collated a couple of tutorials that make it work.
I have managed to get SkySafari to work with a £32 ish Raspberry Pi3 and the cable that came with my scope with a usb to serial converter - the same things you need for connecting to a PC. It allows me to control the scope using the SkySafari Plus app on my tablet or phone AND it creates a wifi hotspot on the Raspberry Pi so it doesnt have to be on a network to work. This also turns the pi into a natty mini wireless router which is handy if you travel since it gives you a private wireless network when plugged into hotel wired internet ?
I AM NOT RESPONSIBLE FOR ANY DAMAGE THAT MAY OCCUR TO YOUR HARDWARE BY FOLLOWING THIS POST OR ANYTHING LINKED TO THIS POST
It takes about 30 mins to do the tinkering, make sure you use the latest LITE version of raspbian.
Raspberry Pi 3 Portable power to it (preferably) Raspbian Lite Image file Appropriate cables to connect your Telescope to it via USB Computer connected to network Network cable to connect Raspberry Pi for initial setup A GoTo / Push To etc telescope mount compatible with SkySafari Plus / Pro A nice case for the Raspberry Pi
You need to know a little about accessing the Raspberry Pi by SSH.
For windows, use Win32 Disk Imager to burn the latest Raspbian LITE image to a micro sd card. Open the card on the pc (called boot) and make a blank file on it called 'ssh' - no file extension. This enables ssh access automatically.
Stick it in your Pi and plug it into your network router and a power source.
Find its ip address - i log into my router by typing its ip address into a web browser and look at connected devices, there are other methods though.
I use a program called Putty to ssh.
There are many tutorials on how to do the above and it isnt as hard as it first seems.
I used 2 tutorials to do this and i will link to them directly as the original authors explain it better than me. The first one is muuuch longer than the second which is just 3 steps so bare with it.
When the first tutorial suggests a reboot after the upgrade, DO IT! Then ssh back into the Pi and continue.
Don't bother rebooting after tutorial 1 either.
Tutorial 1 - Turn Raspberry Pi into a portable wifi hotspot
See 'CONNECTING' after doing step 2 in the next tutorial to actually connect to the scope as what you have just done changes it a bit.
Tutorial 2 - Make it talk to SkySafari App and the 'Scope
You can now unplug the pi from your router. Plug your USB to serial adapter into the pi, your telescope cable into that and connect it to your scope as you would do with a pc (mine is into the AutoStar hand box) and use it as a stand alone adapter just like the £200 SkyFi adapter!
To connect SkySafari to the pi you simply connect your tablet or phone to the pi's network like you would any other wifi network, i called mine Scope, connect using the security key / password you made up in tutorial 1. Open SkySafari and follow step 3 in the second tutorial but with IP address 192.168.0.10 - the port is still 4000 (unless you changed it)
If you are at home and your cable is long enough to reach your router you can plug the pi into that and use your home internet too - which you cant do with the SkyFi adapter!
I am going to shorten my serial cable to make it a neater package, i can always solder new plus to make an extension if i ever need one.
I am also working on finding out how to make it share usb internet so a 4g dongle can be plugged into it when out and about since when you connect to the pi's wifi in the field you will not have internet on the device connected to it.
Also the Pi could possibly be used for imaging or tracking, someone on here will probably know more on this.
