I then took the temperature down to -10 C and got the same swing from -10.2 C to -9.8 C again, with .2 difference from what the set temperature is at -10 C. I can live with that. I was just wondering why the difference between the two different readings...

Yep, I've been watching the temperature and there hasn't been any change. I still am getting 0.2 C and the swing is from -5.2 C to -4.8 C. Okay I dropped the set temperature to -6 C and took a test image. Nope can't tell much in the difference in the noise levels...

Well, I checked the specs on my SBIG ST-9 and it reads; Temperature Regulation ±0.1°C. Also just a note, the ST-9 has a CCD Kodak KAF-0261E + TC-237. I wonder who made the cooler for this camera. This camera is long since been removed from production and sale.

Cooling - standard Single Stage Thermoelectric,
Active Fan, Water Assist Ready
-45 C from Ambient Typical
Temperature Regulation ±0.1°C

I added the water assist to this camera.
Perhaps my next inquiry needs to be directed towards the manufacturers now being Diffraction Limited as they bought SBiG and sale their new cameras now.

HI All,

I am happy with my computer installations for KStars and EKOS. But as you might guess I have a question. My question revolves around my specific set for the temperature regulation in EKOS.
Here is what I have:
I am running the latest version of Ubuntu 20.04 LTS.
I have installed the Bleeding edge for KStars.

I have my CGEM 9.25" telescope attached to my Dell notebook.
I have my SBIG ST-9xme CCD camera setup under KStars and using EKOS.

I have set my ccd cooing temperature to -5.00 C. I watched the changes in the temperature from room temperature down toward the desired set temperature. However, I seem to only get about 0.41 C as the temperature switches from -5.23 to -4.82 and never reading or settling on -5.00 exactly.

I checked the settings for EKOS "Options" "Capture "and the temperature threshold is set to 0.1 C, Guiding settle is set to 0.00 seconds and the dialog timeout set to 60 seconds.

Given these values am I missing something or do I not understand what I need to do to get the temperature regulation settings to reflect the desired 0.1 C threshold to work?
Or, is there something that isn't working correctly with the Bleeding edge version of the software?

Any advice will be most appreciated. Thank you for supporting these great products!
Regards,
John

I am new to the whole Raspberry Pi thing. If I know anything what so ever do these devices operate wirelessly? I will assume that they do based on what I have gleaned from reading about them online. So, the idea here is to install one of these gadgets on or next to your astro gear. Using another computer install an Linux OS. Then you connect everything to the Raspberry Pi. Next using your home network connect to this device. Then you can use server EKOS to connect to the gadget. So it is independent as far as whether you use a Linux or Windows machine with KStars.

My question then would be, is it worth the money and time to install one of these gadgets for my astro gear?

Then there are a lot of choices for purchasing that it would take me a while to sift through all of the options out there.

It does sound interesting.

I do understand what is needed to be able to use KStars on a Windows machine. However, it seems to me that because you can't run a telescope directly from a KStars Windows installation what would be the value of installing it on Windows in the first place? I know there are options other than Kstars. Just my thoughts. I already have several computers running Ubuntu Linux and even one that is a dual boot with Windows 10 Home edition which I have installed KStars and connect my CGEM with.

Okay forget plate solving. I have a set up question. Do I have brain fog? Or, did Kstars (EKOS) show both the imaging CCD and the internal guider window with the same FOV overlay on the celestial map? I thought it did. Perhaps I am just remembering that in SkyX which shows both on the overlay?

Also, being relatively new to the project can you re-orient the FOV overlay? If so, how do you do that?

I am running Linux Ubuntu 20.04 and the latest build for KStars and EkOS on several other notebook computers.

Right now all I see is a square with an arrow pointing north. I let KStars let KKOS detect the FOV information directly from the ST-9 CCD camera. I also let KStars computer the FOV. Without the orientation for the internal guiding CCD this overlay, as it appears to exist, isn't very useable other than seeing the area of the CCD imaging chip.

Some anti brain fog would be helpful.
Thanks!
John

I big and hardy thank you for all you do for us newbees out here. I completed installing your suggested software with the latest versions of Kstars and ppp and all of it. I can report now that I my Linux Kstars does in deed connect to my CGEM mount now. This is a great thing you have done for me and I am not worthy! But thanks so much!

John

Hi all, I am an new registered user to this group. Great to have it and joined! I have revived an older Acer notebook with a new HD. I installed Linux Ubuntu 20.4 which came with Kstars. I have a Celestron CGEM mount that I've been unable to connect to Kstars and the INDI control menu. I have tried several different command line protocols, one to insure that I have permissions. Then when I attempt to connect my mount I get an error message stating "Failed to connect to port dev/ttyUSB0 Error Port Failure Error: Operation not permitted Check if device is connected to tis port".
I did a port search and it finds one port.

I am wondering if my Celestron Nexstar + hand controller is compatible with INDI and with Kstars. I do have the non + hand controller and a Serial to USB adapter that I haven't tried to use yet.
Please pass on any thoughts on the matter.
