Hi Prasad, thanks for sharing your discovery. The normal rule for choosing the width of the image on a ZWO camera is that it must be a multiple of 8, so 3096 should be fine (8*387), but obviously not in this case... In theory I could change the rule programmed into SharpCap to 'must be a multiple of...

Hi Geoff, thanks for the update - just did a check of the mount control related changes between 12025 and 12100 and I don't think there is anything relevant to this situation - basically the changes came down to * Error handling around park/unpark * Changes to how the code waits for the mount to set...

Hi Louis, if you are using a real guiding application (PHD2 or an MGEN guider) then you can either use the recentering option or guiding, but not both. To turn on the guiding/dithering option, turn of recentering. The theory is that when you have PHD2 or MGEN guiding active, dithering is not necessa...

Hi Chris, interesting... If the 'Stop' button is disabled as well as all the other controls then it probably means that SharpCap has become stuck trying to send the movement command to the focuser - ie the code is stuck in the ASCOM driver. We could confirm that if you could try running with the log...

Hi Errol, brilliant! - that not only helps understand what is going on, but also gives a path to fix the problem by some sort of outlier rejection when averaging the dark frames. I have downloaded the shared files so that I can test my solution for this to make sure the sensitivity is appropriate to...

The lack of source code to the ASCOM drivers intrigued me, so I carried on digging. It appears it is not available... https://sourceforge.net/p/arduinoascomfocuserpro2diy/discussion/general/thread/79803561/ Of course, you could decompile the ASCOM driver with various tools available to convert .NET ...

Hi, my thought with the 'one line of python' suggestion was that you could either use it to set global python variables before running a script, or as you have suggested call a function that encapsulates a whole script and pass in the right parameters... I think I will add that as it is nice and eas...

Hi, were you trying to switch the light on or off? I guess so, since the 30s timeout applies to those operations. SharpCap is expecting the light to enter the correct state within 30s of the command being issued. If you are switching on, the calibrator should go to the 'Ready' state, if switching of...

Hi, interesting that the first error in the ASCOM log is 'A device attached to the system is not functioning.', followed by 'Serial port is not connected'. I suspect that the failure to talk to the arduino is happening at a fairly low level (driver? USB?) to lead to the device not functioning error....

Hi, the sensor analysis process and the data it produces is only influenced by the camera, not the telescope that you have it attached to (you can also do the analsis with a simple lens attached, or even with an open sensor). So, you only need to do the analysis once (or not at all if your camera is...
