Hi!

OK, good to hear that you neither recognize it nor can see anything in the log. So I switch USB-cables and will more closely monitor power consumption. As for temp settings, Ii's below 10 here, so it normally does reach -30, however, seemed not do to that last night.

Best,

Magnus

Hi!

Here's another one. I pulled the log while it was "freezing" but cannot makes sense of the log on this issue. If anyone else can, I'd be happy! This is a bit frustrating.

Hi!

I don't have much experience in connecting them to a PCB but there are this type of connectors at least (think there are others as well):

Hi!

I've been seeing this on and off lately: My Atik 383L+ "hangs" on exposure at times. It is to take lets say 180 sec exposure, the exposure starts, and it starts at 180 secs in Ekos Capture module. But it does not count down. After several minutes still 180 secs. I click abort and it restarts and all is OK. It can also happen mid-exposure.

Here is a log where it happens twice: first exposure of V1391 Cas, and the last exposure in the sequence. Anyone recognizes?

Hi!

It has some odd half-official status, to be considered "experimental". Look here:

Hi!

I can easily understand your frustration. However, mine flips very reliably, I would say. It was a very long time since I had a problem with it. I've set it to flip at 2 degrees, I think, and have set the Goto limit at the meridian (don't know exact values right now, but with western limit say 110 degrees, Goto is 20, so any goto after meridian should trigger a flip). I hade issues before but more with run-away slews - disappeared on upgrade of Gemini firmware to the "beta" version that is around.

Anyway: if you fiddle with the driver, I'd be happy helping you out testing!

Hi!

Trying to test this for the first time, I pulled down the code from git. Following the instructions on Github, I should then run
./installLinux.sh

However, I find no such script. Is it still the two install scripts in linux-scripts folder that are to be used?

Hi!

To the best of my knowlegde, the Anderson Powerpole connectors are very common among astro people - replacing the "cigarette lighter" connectors. And I'm talking about these:

andersonconnect.com.au/store/index.php?m..._info&products_id=93

A lot of people for instance use a "Rig runner" on top of their mounts to distribute power to all the devices - based on these. For instance:

www.westmountainradio.com/product_info.php?products_id=rr_4006u

The device your are designing is effectively a far more advanced version of a RigRunner (sort of).

Hi!

Why not an Anderson Powerpole connector for 12A?

Hi!

Do I get it right that the shutter release works as expected on the R-Pi and another Linux computer, but not on your laptop?

In that case, it must be a matter of software on the laptop, I'd think. What system do you run on the laptop then?

My first idea would be that the shutter release is not correctly identified on the laptop - either the driver is missing or it is not corretcly set up in Indi. Check in the Indi control panel which USB device is identified as the shutter release and which is identified as the camera.

Here's a page about the shutter release cable. Not sure where you can buy one these days, though.

Hi!

Yes, two cables, and then I don't really remember - it was some time ago. I think it was perhaps a matter of identifying them correctly (USBtty0 and USBtty1, I think) - which is easily done by unplugging one and see with for instance dmesg which one it was. I think setup is fairly straightforward, once you have the correct shutter relase-to-USB-cable. Unfortunately, I can't find a link to one now.

Hi!

I can almost, but only almost, decode the German... :)

Your question about cables: yes, I had two cables. On shutter release, and one regular USB-cable. And I controlled the camera with Ekos/Indi. Worked very well. But I now use a CCD instead.

Thomas,

No problem reading :) which is your native language, by the way?

I very much doubt that GPhoto could produce exposures for more than 30 secs over USB - as I understand it, this is a matter of the design of the camera, not the driver.

If you have one that works - could you not try attaching a serie-to-USB-adapter to that and connect to the computer? My old cable is has the small connetor to the camera on one end (like an earphone-plug) and a serial D-Sub in the other end. The serial D-sub was then connected to a starad RS232-USB-adaptor like this:
www.dustin.se/product/5011025600/usb-to-...Y366kbMaAkpcEALw_wcB

Which has a USB connector in the other end. And that one to the computer.

I think you can still buy the whole serial release cable online, but I cannot recall from who I bought mine - someone in UK.
