The cameras that are most suitable are Canon 450D, 650D, 1100 etc, basically any of the ones covered in Rowland's thread. Newer DSLRs are too tightly packed and produce more heat when used for astro work. A better investment might be an ASI1600MC-C if you want OSC, ASI1600MM-C if you want mono.
Do you have a link to threads by Rowland?
Who is he?
