Equipment wise (mounts, camera accessories), yes, what to do with your newtonian, well yes and no. I don't have a newt so I can't speak from experience, but if you can't reach focus (usually not enough infocus distance) then yes the mirror will most likely need to be moved up the tube. You don't have to cut the tube end off, but it does make it more difficult to reach the collimation screws.
Another option is a low profile focuser, but there is no guarantee that you will be able to reach focus with that either.
I've just gone back and read what scope you have, what do you have it mounted on?
If you meant can I advise you on planetary, luna and solar stuff, then yep np
