The camera has a 14 bit A/D converter and QHY website says it should produce 14 bit encoded video files.

However, in EKOS / INDI I always get only 8 bit encoded SER files.

In the INDI control panel it shows 16 bits per pixel and it cannot be changed.

Am I missing something or is this a bug with EKOS / Indi

Is there a roadmap to support KStars/EKOS natively on Apple Silicon?

The Intel versions runs but..... lots of subtle bugs. Mostly related to driving cameras. Mount control seems ok.

Other devices might also have issues but no experience with those.


Using the most recent version of KStars.

Scope : SkyWatcher Quattro 300p
Mount : Celestron CGX-L
Camera : Sony A7R4
Polar Alignment : QHY PoleMaster (this works flawlessly)

The solver works reliably but the mount does not seem to make the correct movements to sync onto the target.

Last night I tried to have it sync to Polaris and it never even got close and the movement choices were not logical in my opinion.

Needless to say being able to plate solve and slew to target is essential.


Sorry if this is not correct category for this question.

I have a QHY5III-178M.  According to their web site (  this camera the A/D is 14 bits per pixel.

When I record a SER video it only uses 8 bits per pixel.

Is this normal?  It the camera unable to stream video at 14 bits per pixel or is it an EKOS / Indi limitation?

Do I need to change a setting someplace?  

In the INDI properties for this camera it shows 16 bits per pixel and does not seem like it can be changed.

Does gain / offset have any effect when recording video?

What default values of gain and offset should I use as a starting point for both solar imaging and DSO imaging?

Thanks in advance for the help?



One more piece of data....

Inside my house, with ambient light provided by windows, the video does show an image.

However.... changing gain / offset does not seem to change anything and cannot get FPS above 5.8



I actually got this camera to use for guiding but not ready for that yet.

Wanted to try using it for some deep sky imaging.

Quattro 300p
MacBook Pro M1

KStars connects to camera without any issue.


During the day doesn't seem to matter what Gain / Offset I try video remains full white screen.
At night video, even though I can see lots of stars, is completely black.  Also does not seem to matter what Gain / Offset I try.

At night I can point camera into my lighted garage or at a street lamps and video looks good.  Changing Gain / Offset does not seem to change anything.

I am on the CCD tab in Ekos doing these tests.

The other thing is no matter what I do the frame rate is around 5 fps even though this camera is supposed to easily do 50 fps at full resolution and even higher at reduced resolutions.

My normal camera is a Sony A7R-IV and when it is in the scope I can see hundreds of stars with live view.

I was really expecting the mono camera to be more sensitive or at least as good.

I also have a QHY PoleMaster and it can see lots of stars.
In my neighborhood, in PoleMaster, I use exposure of 300ms and gain of 100.

In KStars I cannot increase the gain above 51.

Anyway hoping there is a simple answer and thanks in advance for the help.

Mount Type: Meade LX-200 GPS

Why this mount type and not what you actually have? Does EKOS translate commands from SkySafari into correct commands for your actual mount?

Why chose mount = Meade LX200 as opposed to the mount you actually have?

Does EKOS translate the commands from SkySafari into the correct commands for your actual mount?

Is there any way to start EKOS without KStars or use it by itself?




Is there a way to confirm the solver in Ekos is working by using an image captured previously? In other words test with a real image and not using... Show more
