Hello,

While I done polar aligning perfectely, after an update it no longer wants to do it. There is a message about WCS.

2017-06-15T14: 25: 55 Warning: Failed to load WCS data in file: No world coordinate systems found.
2017-06-15T14: 25: 55 WCS data processing is complete.

2017-06-15T14: 25: 54 The calibration program was completed in 3 seconds.
2017-06-15T14: 25: 51 Starts the Resolution Program:
2017-06-15T14: 25: 51 Image captured.

I did not have this problem before. What is going on ?

The capture & resolution function works perfectly.

I just ran into this issue. What you have to do is to capture & solve an image (not iduring the polar align routine) then you will get a message about wcs being correct now. Then you can complete a polar align without that error message

I check in Kstars FITS setup the parameter WCS.
On the CCD I activate the WCS, filling Rotation with the value from the capture & resolution.
So the polar aligmnent runs.

I am sure before the update I have not use this settings.

One of the last updates removed the automatic WCS processing because of some issue on slower machines. I think there is some issues still with the new WCS processing as I am getting a seg fault if the AutoWCS is turned on.

So that error is not really important per se, but I just fixed it anyway. If you already run an alignment before you start Polar Alignment Assistant tool then WCS data is already valid, but if you use it straight away after you begin Ekos then there is no valid WCS data. At any rate, I now made it simply take another capture if there is no valid WCS data. Should be in the next KStars release.
