Getting the following error when attempting to download images from my ASI1600MM Pro; [2019-03-28T16:02:28] [ERROR] [MemberName] DownloadExposure [2019-03-28T16:02:28] [ERROR] [FileName] D:\Projects\nina\NINA\Model\MyCamera\AscomCamera.cs [2019-03-28T16:02:28] [ERROR] [Message] Index was outside the bounds of the array. at NINA.Model.MyCamera.ImageStatistics.CalculateInternal(UInt16[] array) at System.Threading.Tasks.Task.Execute() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at NINA.Model.MyCamera.ImageArray.<CreateInstance>d__14.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at NINA.Model.MyCamera.AscomCamera.<>c__DisplayClass197_0.<<DownloadExposure>b__0>d.MoveNext()

Strangely it was working when I first started trying the app. My QHY5 guidescope also works through the ASI built in USB hub.

Hi, what is your bitdepth setting set to?

[James]

Raw16. This problem exists with the Ascom driver. I tried the native ZWO driver and it is working flawlessly.

[Stefan B]

Is it also set to 16 in the options->equipment->camera settings?

[James]

That looks like the problem. It was set to 12. That is interesting because 12 is correct, this has a 12 bit ADC?

[Stefan B]

Ok. Yes the problem here is that even though the sensor is 12 bit, the data that is generated by the driver is stretched to 16bit. This is a known issue, which is not handled gracefully yet by N.I.N.A.

[James]

Thanks. I searched for the error and couldnt find another issue. Impressed with nina so far!

[Stefan B]

Thank you. I will leave this issue open, but set the priority to minor, as there is a workaround. It will get properly fixed at some point.

[James]

Thanks. Now I know the source I will probably switch to the native driver and avoid the performance bottleneck of ascom.

Fixed by #8bb24b22

Fix Issue #148 - DownloadExposure when bitdepth is set incorrectly
