Hi Morry.
Geez, even after years of practice I find it hard to locate a planet with a 9mm EP in a Dob.
Start with a bigger EP like a 15mm or 20mm. A 25mm would be even better. Then centre the planet (or other object) in that EP, then quickly swap over to the 9mm.
Also, you will need exceptional seeing to get a good view with a 6mm EP.
What you will learn as you go along is that the more you magnify an object the faster it will zoom through the EP view, and a slight move of the scope is an enormous move in the view
