Hi,
Image scale is very important in astrophotography. The resolution of you images will be limited every time by the seeing conditions at your site.
You have to know the image scale of your setup in order to see if you are oversampling or undersampling your target.
A nice article on image scale is the following :

Another link with software that will help
you plan your photo session before hand and also calculate your image scale, is the
following :

Clear Skies!
