Hi Robin,
As I mentioned (yesterday?) I have suffered several times a strange error while using my camera (QHY268) in still mode.
My perception was that the interface did not allow to take any exposure via any way: all exposing buttons disabled, all exposing menus dissabled.
You mentioned that the software could be exposing at that time and this could be the reason.
It happened today again and I can confirm you that this is the case ... the exposure information raises continously 100/100 >> 101/101 >> 102/102 ...
Meanwhile all menu and button options are dissabled (including STOP capture).
Today I have seen this after several attempts of solve and sync (the exposure to solve was eternal and ended about 120 & 200 secs latter ... it should have been 2 or 4 seconds long). The final image after all this time was never shown.
Today I have seen this (later) as part of a sequence where a 5 min exposure has taken 26 minutes until I have breaken the sequence and reconnected the camera.
In any moment I can switch to live mode and this works fine. Going back to still mode has sometimes solved the issue, sometimes not.
I think this is the log that shows it all (I had to restart the application a couple of times). The platesolve errors are just after starting (about 23:45) and the sequence error was about 00:07 (if I am not wrong)

Re: Camera not responding and taking eternal exposure
Hi,
thanks for the log - a 5 minute exposure is started at 00:07 and at about 00:12:20 SharpCap asks the QHY SDK for the image data - this call finally terminates at 00:33:45 - about 21 minutes later! There are also a couple of other places in the log where the request to read the image data is taking too long
It looks like cancellation requests are getting the image readout to eventually abandon waiting in each case - that's good in one sense that the cancellation is working, but maybe that cancellation is not putting the buttons back to enabled - I will have to check.
In theory, the image readout from the QHY sdk is supposed to timeout 30s after the exposure time has elapsed - apparently this is not working properly - I'm not sure if this is something I can fix from the SharpCap end - I will run a series of 300s exposures on my 294C to see if I can get that to break at all (If I can get it to break I might have a chance). It may be worth reporting this to QHY - the place it is getting stuck is inside GetQHYCCDSingleFrame. I think they have a way to turn on logging inside the SDK which might bring out some information that helps them understand the problem.
thanks,
Robin
