Voyager uses ASTAP natively and it works like a champ. APPM doesn't solve repetitively enough for me to be
concerned about it.
I don't even understand what that means?

APPM does not natively plate solve. It uses an external plate solver. It simply reads the RA/Dec and other values from the solver,
or intermediary app.

For plate-solving I typically use PinPoint and all-sky backup to Astrometry.Net. I've done many thousands of plate solves. Maybe
even hundreds of thousands. Unless there is a tree, clouds, or something else obscuring the sky, plate solves have been extremely
reliable at the image scale I typically use (around 1.6 arc-sec/pixel). That said, PinPoint can have problems in areas of the sky
where there are too many stars in the selected database, typically around the milkyway.

If the image area is smaller, for example because of a longer focal length, it may be more of a challenge.

It could be as simple as the fact that APPM is doing a large number of plate solves in a short period of time.
I hope that's not true because it might make ASTAP a poor choice for plate solving.

I agree.

I suspect that it's an ASTAP problem, but something that APPM is doing is exposing it. It could be as simple as
the
fact that APPM is doing a large number of plate solves in a short period of time. As I mentioned, I've not had time
to do any investigation at all yet.

I switched to ASTAP for my plate solves with SGP and am seeing what is
probably the same issue described in the first post of this thread.
APPM doesn't know which plate solver is in use when SGPro is used for plate solving. APPM operates the same
way for all SGPro plate solvers because APPM uses the SGPro API for plate solving. Since PlateSolve2 doesn't
seem to show the same problem, it seems likely that the problem is with how SGPro handles ASTAP.
