Default Magnification?

You can calculate magnification by
'focal lenght of telescope' / 'focal length of eye piece'

If I put my Nikon D70 (chip size: 23,7 x 15,6 mm) at prime focus of a

scope
with focal length of 1500 mm, what is the magnification of this system?


The field of view will be 54x36 arcmin (courtesy of K3CCDTools)
