I am experiencing problems with a QHY9 camera as well, though in my case the problems are with the filter wheel. See

www.indilib.org/forum/ccds-dslrs/3872-qh...x-mac-ok-though.html

I haven't found a soliution yet and will keep an eye on this thread just in case...

To find out if Kubuntu sees the USB cable, open a terminal with the mount disconnected and type

lsusb

which produces a list of connected USB devices. Next connect the mount and repeat the command. It should be listed.

The camera only started behaving li,e this recently. I am not sure if this was with KStars 2.9.8 or later but I am sure I didn’t change the power saving setting (nor any other for that matter) on the camera.

I occasionally see this too with my 700D. Stopping Ekos and KStars and switching the 700D off and back on fixes it. No reboot needed. I haven’t been able to reproduce it nor to produce logs unfortunately.

Can anyone tell me how to revert to an older version of the QHY driver on Linux? Or to an older version of the SDK?

Jasem, would you mind contacting QHY and ask them if the QHY9 camera and old filter wheel are still supported by the SDK?

I am using a DSLR camera so to my best of knowledge there is no WCS data in the files. I use Astro Pixel Processor which does a great job identifying the stars and star patterns in the files. Not sure how though...

Thanks, I’ll disable Remember Job Progress next time!

I am using my Odroid without an HDMI dummy or real display connected via VNC all the time without problems. For this I use the Xorg.conf file I posted earlier. Doesn’t that work for you?

Wouter van Reeven replied to the topic 'Re:Warn if scheduled jobs have the same name' in the forum. 5 days ago

Thanks I’ll look into all of that as soon as I can.

I created two jobs with the same name so the output frames end up in the same directory and I can load the frames in my pre-peocessing application more easily. And to clarify once more, from my point of view the jobs aren’t identical since the coordinates are different. They are merely very similar

Hi,

I am working on a mosaic of the North America and Pelican Nebulae and ran into an issue with the scheduler. I added two jobs with exactly the same parameters apart from the coordinates of the center of the FOV. When the first job ended Ekos thought that both jobs had ended because they had the same name. Only when I have the 2nd job a new name Ekos would start it.

Would it be possible to add a popup or other warning when two jobs with the same name get added to the scheduler? Many thanks in advance!


Clear skies, Wouter

The day before yesterday I dedicated a whole night to color imaging with my QHY9 CCD and filter wheel. I took images of the Dumbbell Nebula and Stephan's Quintet using R, G, B and L filters. Or so I thought. When I processed the images of the Dumbbell Nebula, it looked oddly colorless, apart from the edges of the image due to dithering. Close inspection of the images revealed that they all looked exactly the same, apart from guiding issues due to wind and fainter stars because of clouds passing occasionally.

So I took the camera off the telescope, attached it to the Odroid machine that I use with it and started Kstars. This revealed that the filter wheel does NOT turn and always stays at the first filter. Ekos, however, thinks it does turn because the images were put in directories with the filter name. I also tried on my MacBook and there the filter wheel does turn, suggesting this is a Linux driver issue. Both tests were done with the latest and greatest KStars 2.9.8

I attach log files from my Linux tests but I am afraid they do not show any issue. Tonight I'll image via my MacBook but I would very much appreciate it if this issue could be resolved. I don't mind compiling drivers myself or replacing files on the file system if it helps testing.


Thanks, Wouter

The unit of RMS is arcsec so with 4,54” pixels and 1” RMS you get sub-pixel accuracy.

Wouter van Reeven replied to the topic 'subpixel accuracy - autoguiding' in the forum. 7 days ago

That depends on your guide cam, guide telescope and RMS. If, for example, the guide cam plus scope give 1” pixels and the RMS is less than 1” you get sub-pixel accuracy.

Strange that a second window manager is created. As I said, I use vino and make sure that
- the Odroid user get automatically logged in
- vino is a start up application

And then I can connect to the same instance as when an HDMI cable is connected. The xorg.conf file I use is

Section "Device"
Identifier      "ODROID"
Driver "armsoc"
Option "Debug"         "false"
Option "DPMS"          "false"
    Option      "NoFlip"    "false"
Option "NoHardwareMouse" "true"
    Option      "NoG2D"     "false"
EndSection

Section "ServerLayout"
Identifier      "Default Layout"
Option "BlankTime"     "0"
Option "StandbyTime"   "0"
Option "SuspendTime"   "0"
Option "OffTime"       "0"
EndSection

Section "DRI"

        SubSection "Display"

        EndSubSection
EndSection

and I don't use xrandr.

It is possible to start a VNC server on the same display :0 as where the HDMI screen is connected to at the same time. When you then move the mouse, for instance, in the VNC client then you’ll see it move on the HDMI screen as well.

What happens if you start the VNC server on :0 as well? That's how I use VNC on my Odroid XU4 running Ubuntu MATE 16.04 and have no problems whatsoever. FYI I use vino as VNC server with the RealVNC client over an unencrypted VNC connection.
