I'm not an expert but I think it depends on if you are going to be going for deep sky objectgs or planets. Anybody else got an opinion?

The f/750 is the faster scope for photography but it is also likely to be more sensitive to collimation errors but the tube is shorter so a little easier to handle. If this is a first scope have a look at http://gardenastronomy.moonfruit.com
