It solved successfuly and reports a rotation of "93.1 degrees East of North"
Not really sure what that means? Rotation is approximately +93 degrees??

Astrometry's solution 'rotation' question?
I just solved an image on Astrometry .net
It solved successfuly and reports a rotation of "93.1 degrees East of North"
Not really sure what that means? Rotation is approximately +93 degrees??

Re: Astrometry's solution 'rotation' question?
I did a visual comparison and it ends up being a rotation of 270 degrees ?

Re: Astrometry's solution 'rotation' question?
Possibly it's explained by "position angle", which is measured positive INTO the direction of right ascension, i.e., to the west. Perhaps that's the context for the value from Astrometry .net.

It says UP is 93.1 degrees East of North.
But when I compared images I found it to be around 270 degrees of rotation?
