Using the same process steps, same FOV/scale, I've used successfully before, first solving image then using PCC, today I get:
Followed by other errors because of this.
I've tried forcing the solve again, which succeeds but gives the same error, and messing with the magnitudes, to no avail. Note that according to Stellarium my image contains mag 11 stars, and the auto setting is looking for 0..16 so it should work.
The "FOV:0.491 actual:0.000" looks suspicious.
Here is what is coming back from Vizer:
Thoughts?
