Same thing, different price
Others that have more experience with newtonians will have more knowledge in this matter but I have heard that it can sometimes not be possible to achieve focus with a DSLR if the primary mirror is set back too far. I have never done imaging on one though.
If you're wanting to do deep sky stuff you will also need to get a coma corrector for it otherwise your stars will be less and less round the further they are from the centre. It should do fine for planetary though as far as I am aware. As long as the primary and secondary mirrors are accurate aligned.
