I am a beginner.  I was running my setup initially with ASI Air but decided to give NINA and CCDCiel a try.  I've had trouble getting things running.  I am running a mini PC with a Pegasus Gen 2 distributing power and USB services.

 

I can't get my filter wheel or rotator to connect.  I have uninstalled everything and reinstalled just ASCOM and the camera and other ZWO driver package.  I ran the ASCOM diagnostic program to see if it recognized the devices.  The camera is recognized and shows up in Device manager as well.  When I try to connect to the Filter Wheel I get the following:

 

Create              Creating device
Connected           Connecting to device
Error               System.NullReferenceException: Object reference not set to an instance of an object.
   at System.Dynamic.ExcepInfo.GetException()
   at System.Dynamic.ComRuntimeHelpers.CheckThrowException(Int32 hresult, ExcepInfo& excepInfo, UInt32 argErr, String message)

Dispose             Dispose is not implemented inthis driver
ReleaseComObject    Releasing COM instance

it seems that Object reference not set to an instance of an object is the problem.  i have no idea what to do to fix this problem.  Removing all programs and drivers and rebooting the mini computer did not work.  Any advice?

Ah yes, the old ASCOM-driver-computer problems.  I remember them well from the good old days several years ago, before I switched to asiAir.
