M45 feild curvature

[libraryman]

I'm not sure if this is the correct place for this post but here goes, i am new to CCD inspector and have uploaded a 180sec sub of M45 analized in CCD inspector

Would someone familia with CCD inspector tell me if what i am seeing is a lot of feild curvature because my subs dont seem to show this much

Have to admit it was a difficult question to answer, having looked into CCD inspector a little more, i have gained a little more understanding and i should have used more subs, this would have told me that my feild curvature, collimation etc aren't that bad

Thanks for looking
