Hello,
Here is an illustration of the difference between imaging with a 6 mega pixel DSLR and 0.3M (640x480) pixel DMK.
The background image was taken with my Vixen 4” refractor at F9 using a Pentax *ist DS DSLR at prime focus (fl=918mm).
The inset image was taken with the Celestron C9.25 with an F6.3 Reducer/Corrector and the DMK21AF04.AS at prime focus (fl=1500mm).
It shows nicely the differences between fl, sensor size and colour/B&W.
Cheers
Dennis
