file saved that's messing things up (e.g. delete your ~/.local/share/kstars/<wbr><a \
href="http://SavedFocusProfiles.ini">SavedFocusProfiles.ini</a><wbr> file if it exists, and then make \
sure you're using the "1-Focus Default" profile). You could play with the initialKeep and keepNum values \
in the kstars/ekos/auxiliary/<wbr><a \
href="http://stellarsolverprofile.cpp">stellarsolverprofile.cpp</a><wbr> file in the Focus method. (Also \
see the note to Rob below). <div><br></div><div><b>Rob:</b> could there be a bug that if you \
have a saved .ini file, then the initialKeep parameter no longer gets set and uses a very high default? I \
