Hi,

I'm new to Ekos and trying to understand operations. Yesterday, I set up my RPi as a server, and was controlling everything from my laptop. System is set up in my living room for basic testing. I was able to get some images from the camera indicating it was working - uncap the telescope, take an image, get weird bright out of focus picture.

Today, it seems like the camera shutter doesn't want to open. I can set the exposure to 5 seconds, which should produce a completely white image, but instead I get what looks like a bias image. Listening carefully near the camera, I can't hear any shutter action.

Just in case it's a hardware issue, I tried the camera from my Windows installation and it works just fine. Switching back to Ekos... it doesn't work.

I'm kind of wondering if I have everything set up right. In the INDI control panel for the camera, there are "Shutter - Manual open / Manual close" buttons. I don't want manual anything here. What do these buttons do?

Software details: Raspberry Pi running Raspbian - libindi updates downloaded yesterday. Ekos VM 1.6 downloaded a month ago ; all updates applied.

Thanks for your help,

Charles

I can add that if I capture a 300 second exposure, it looks like a dark frame. In other words, the camera is actually exposing for the right time (I assume) but not opening the shutter.

I've had similar problems for a while as well that the camera doesn't always open the shutter then taking light frames. The workaround that has worked pretty well is to take one dark frame at the beginning of the session and it usually works fine after that. Ie. set frame type to dark, take 1 second exposure, switch back to light frame type. Not ideal especially with Ekos scheduler, but better than nothing.

Thanks. I'll give that a try next time I have time to get this running.

Well I tried it and I can get the shutter to open. It seems the workaround does work. However, it would be nice to be able to control the shutter, or at least to have it work sensibly for other images.

For instance, a bias image is generally taken with the shutter closed. But Ekos doesn't do that when you select "Bias" as the type. Workaround is to set the type to Dark and change the filename accordingly, then move the images out of the "Dark" folder into the Bias folder.

This would be nice to get working. Another option would be to have a shutter control button that is another parameter in the sequencer job.

Thanks,

Charles

This is strange, I have an Atik 383L+ mono and have never experienced this with INDI/EKOS.
What version of the driver from cloudmakers are you using? I'n using 1.22

I've used pretty much every version from 1.12 to 1.23 so far, the difference might be that we are using ARM driver on Raspberry Pi and you seem to use Intel. I had similar issues with Cloudmaker's USB Focus V3 driver, which didn't work on ARM but worked fine on Intel and it looked like uninitialized variables or something as the settings were full of garbage. Could be that the frame type isn't always properly initialized on ARM so it doesn't quite work until set to a different value and back. Just a guess though :)
