Is anyone successfully using Kstars/Ekos with an EM1?
I am running Stellarmate on a Beelink mini s12, and find Ekos does not see the camera connected by USB cable.
I'll assume you're referring to the original Olympus E-M1 from 2013, and not the Om System OM1.
The E-M1 should readily work in Ekos. Did you set up a profile first? You need to select GPhoto CCD as the "DSLR", and save the profile. Make sure the camera is on and set to BULB before starting the session. I'll assume you have the proper USB cable.
When you first connect it and start a session, a small camera parameters box will pop up asking for the resolution and pixel pitch of the camera, which in your case is 4608 x 3456 and 3.72 µm (x2).
However in the latest versions of Ekos, when you first start the session up, this box can easily be obscured, because in the new versions of Ekos, very annoyingly, Ekos immediately pops up the Optical Trains box, which is associated with the main planetarium screen, and can wind up burying the camera sensor parameters box. If you miss entering this information, you will not be able to use the camera.
So what I suggest doing is dumping the profile you've already created and create a new one, and when you start up the session, pay attention to the small camera parameters box that pops up. It will almost immediately be obscured by the optical trains box and the main planetarium screen, but if you look on top you'll see multiple tabs for the different opened windows. Select each tab until the camera parameters box comes to the fore. Enter your camera parameters, and click OK. The camera should now be recognized. You will only need to do this once.
Once past that hurdle, go to the INDI Control Panel window, which should still be up. Go to the Image Settings tab, and set the file format to RAW and Native, as it will probably be defaulted to FITS. You should also set your starting ISO, which in the case of your camera should be 800 or 1600 (do not use intermediate ISOs). Then go to the Options tab and click on Save. You can close the INDI Control Panel then.
Your camera should now be recognized by Ekos, and you should be able to continue setting up your hardware. I use an E-M5 Mk II from almost the same era, and it readily works in Ekos.
