Hello Han,
in ASTAP version June 25, I get a division by zero error, if the zoom is above 2000%.

Hi Achim,

I don not see it here (Windows version). Can you share the image involved? Share also your .cfg file. (You could first save the .cfg to your desktop for locating it) Maybe it is related to your settings.

Hello Han, here is the (Windows 11) cfg. The Fits is too large for direct upload.

Hi Achim,

Thanks for the feedback.

I found and fixed the problem. The zoom dimensions can not be larger then a little more then 65535. Above this value a run time error occurs There is normally no check for this so I build in a check in on the image width only. You image is in portrait orientation and the stop I build in acts too late on the width.

I put now a check in for both the width and height. This fix will be in the next version.

Cheers, Han
