Thanks Seb. Is the difference between the DBK and the DFK the IR-pass filter?
At this stage, having a DMK41 for the Moon, I am toying with the idea of getting a DBK/DFK21 for planets, or a DSLR for general astrophoto. It all comes down to funds. I was warned that astrophotography was a expensive hobby. Boy, they were right
Cheers,
Eric
