Sadly it is rather hit an miss in finding a camera lens for astrophotography
with minimal coma and no CA.
I did
this write-up a while back on the subject.
APO scopes often have excellent CA but unless they have a dedicated field flattener you may find the off-axis result is not what you hoped for.
The William Optics Redcat/SpaceCat series of lenses are however beautifully corrected across the entire frame of a 35mm but while very impressive for sharpness, they are a little on the slow side as F-numbers go.
Interestingly the likes of Canon are lifting their game with their EOS-R series lenses...not cheap, but their new designs show great promise.
