Steps to reproduce:
1. Select simulatorprofile
2. Select internal solver or local astrometry
3. load file and slew with selection slew to target
4. When it it finished, press capture and solve
Result:
If internal solver was selecter then kstars process will load CPU and only killing process will help
If local astrometry selected - then it is astrometry process
The issue happens only when you do not set "Use position". So you get a solution, but seems astrometry or internal solver continue to searchf or the solution
ASTAP: make sure focus is perfect. e.g. if you're using a low end refractor, don't use a focusing mask. Don't bin the image (I think the default is 2x2)
Uncheck:
Seems that option was unchecked. So my observation is that kstars continues to use internal sover or astrometry after finding solution when "use position" is unchecked.
