Ad Astra Observatory

I’ve been thinking about printing out a book of my astrophotos. 8×10 and 16×20 are both 4:5 (1:1.25) sizes. So while the native resolution of the D70 is 3008×2000, the max 4:5 resolution out of the D70 will be 2500×2000.

About publishers, snapfish (for instance) does 20 8×11 pages (that’s 10 sheets, double sided) in a hardcover book for $20.
