What the French man said.....It will be a no go with a guide scope at 3000mm focal length.
What scope are you using?what mount are you using?these will dictate how much difficulty you'll have guiding.
If you really want to have a hassle free experience guiding such a long focal length get a ONAG and forget the rest.
Hey,you'll even be able to guide with a very sensitive can of tuner
