Test case 1: Enable dithering, move the scope close but east of the meridian and start a capturing sequence. In order to ensure, that the meridian is crossed while dithering, run kstars inside the debugger and set a breakpoint before the call of dithering. Check, if after the meridian flip guiding is restarted.
Test case 2: Enable dithering and create a schedule that uses a capture sequence with more than one capture. Start the schedule and interrupt guiding after the first capture while dithering. Check, if capturing and guiding resume. Test this with and without the option for aborting guiding after dither failure set.
