I would like to try an write a 3rd party driver. Are there any instructions for building from  the source for Mac?

Thanks

That's interesting. Kstars runs fine on the LTS version. This was my first linux build other than RPI Astroberry and FreeNAS which were pretty much canned products. I did notice that the Mac version of Kstars has slight differences from the Kubuntu version as I mentioned above. I am not sure if EKOS is from indilib.org.

I rebuilt the system and everything seems to work now. This might be a little off topic but I was running on a Mac but went to kubuntu to to run Pixinsight Ez Stack on a platform fast enough to stack 61 mega-pixel images. On the fits viewer I cannot find the FWHM feature that I use all the time on the Mac. Is this feature just not there in EKOS on Linux?

Thanks Michel that is very helfull. I will rebuild the system using 20.04.02 LTS.

Thanks Scott. I did follow that guide before I tried Snap. I go tthe following results:

I tried to install Kstars and the just Indi following the respective instructions but neither would install because of errors in resolving dependancies that after some googling I was powerless to fix. I must say that I have little familiarity with Linux. So I just installed it using "snap install kstars". I could manage this single step install. So kstars runs and when I launch Ekos Indi immediately crashes. And crashes on auto relaunch. My hardware is a Theadripper 3970 with 128GB, Gigabyte Aorus WiFi Pro, and MSI GEFORCE 3070. Any ideas?

Thanks

I thought I would add this: My A7R4 only randomly saves the image and I couldn't figure out when or why it does or why it doesn't. I have run on the RPI/Astroberry and the Mac with the same results.Yesterday I discovered that using the Sony DSLR driver and just executing from a sequence that the images get stored normally in the local folder. I had never used the collection sequence before and was just using the single and repeated collections buttons in the lower right of the Camera window.

I am running Kstars 3.5.2 on a Mac and just added the SV305 camera but when I start EKOS I get this error:Driver indi_sv305_ccd was not found on the system. Please make sure the package that provides the 'indi_sv305_ccd' binary is installed.

How do I fix this. I read a post about this on the RPI but it didn't seem to be a solution for me.

Thanks

Wow there is a lot of code there. I spent some time looking at it and my first guess is that this uses the libgphoto2 and makes direct calls to the library. I have been using the command line gphoto2 with the following command:

gphoto2 --wait-event=10s --capture-image-and-download --force-overwrite --filename xxx.jpg

So I don't actually know what the wait-event waits for but after the command is issued nothing happens for several seconds and then the shutter clicks. The code you direct me to seems to be in the area where INDI waits for the image to download. On photo if you don't wait long enough nothing happens in the camera. You don't actually capture a photo. So it isn't like a failure to wait for the download to finish.

There is some discussion here: github.com/gphoto/gphoto2/issues/272

I also discovered that gphoto2 supposedly can control the focus so maybe I could write some code to add that to INDI so sunny camera users could use the EKOS focus feature. That might be a bridge quite far but maybe not too far.

Still no luck getting pictures downloaded to local host. I switched to running Kstars on the Mac connected directly to the mount and camera via USB. The A7R4 reliably downloads fits images but no raw or JPEG files are saved using either the photo or Sony DLSR driver. Funny thing is that using gphoto2 on Mac command line will download both RAW, JPG, or both but only when a --wait-event=10s option is used I am wondering if a wait option is needed in Indi

I am using the A7R4. It seems to work fine. I saw some strange exposures last night that were 1/10th second but the ones longer than 1 sec seemed to work. I tried using the gphoto driver last night instead of the Sony driver. I have tried running on both the RPI and Mabook. I have tried a lot of things but can't get the photos to download to either the RPI or MacBook. Strange though is that I do get the FITS returned. My RP4 8GB running Astroberry is really too slow for this. It is ok for general astrophotography when you exposures are very long and you don't care but trying to adjust lens focus is a pain because of the speed to analyze the fits. I am considering buying a Mac Mini and remote into it.

Just as an update. I was able to take the Sony SDK and modify it to add a focus control. So I have an executable that I can invoke and pass it the desired focus position of the lens as a command line argument and it will set the focus. I can then execute a gphoto2 command that captures and downloads an image. Wrapping this with a simple Matlab script I can measure the FWHM of a star and search for best focus. It is not integrated into EKOS but it is a workable solution.

I'll try that. There are probably a lot of things I am missing that I should be doing.

I thought I would follow up with what I have learned. I now use the V4L2 which gives the iGuide camera and makes me fowl better that using iPolar. Set the detector width to 1280 pixels in the INDI panel and set the pixel size to 3.75 as it defaults to 640 and 5.6. You have to do this every time. EKOS won't let you set the integration time longer than 0.5 but PHD2 will allow you to set it up to 3.5 seconds.

Because you need to set this every time you start EKOS you can change the guid telescope to 5.6/3.75*120 = 179.2mm which it will remember. This gives the same IFOV are 3.75 @ 120. Then you only need to change the 640 to 1280.
