--- Comment #5 from mountainai...@outlook.com ---
Jasem, I had a rough time with polar alignments again tonight.  After getting
Polaris in the right spot in my finder scope (I know this isn't a PA scope), I
did a PA with Celestron's All-Star-Polar-Alignment routine (I almost always
need to do this otherwise the KStars PA fails).  I then tried KStars PA and the
mount immediately slewed to its limits again.

This led to an epiphany: I have an EdgeHD 9.25 with 0.7x reducer and an
ASI1600MM-Pro camera.  The resulting FOV is 0.62° x 0.47°.  I just noticed in
one of your videos that you need a 1° FOV.

This suddenly explains my difficulty.  Even with a reducer, my FOV is too
small.  If I am very closely to being polar-aligned (after I do ASPA), it
works.  But when I am close but not close enough, KStars slews the scopes to
the limit.

Two suggestions:

1) After the first plate-solve (which always seems to work), warn the user if
their FOV is too small.

2) When the FOV is too small, detect this and do not slew the scope to its
limits.  I believe this to be a serious bug, because if a user's slew limits
are not set this slew action could damage their gear.

These long-focal-length scopes really don't have many camera choices that would
work.
