Ahh: o.k. Ken, thank you for replying....i use what i assume is a pretty STD method in that I use a local astrometry search! for a recent image I've taken.
By using the gear icon I select my image and then solve, I don't normally blind solve.....I expect and usually find that it solves within 20sec.....fine.
It's just that I have to keep changing the hint from 2.1 arcsec/ pixel to the correct image scale....if I dont, it keeps failing.
Not a major issue, just trying to understand it.
