Hey Joe,
When you get a chance try looking for the red and rusty hues in M42, the Orion Nebula's wings. They will definately be doable in your scope since I have seen those hues in my 10" GS dob. Also check out some of the planetaries and look for internal detail. The Ghost of Jupiter in Hydra is a good one (CBS eye center). The Eskimo Nebula in Gemini is another good one for internal detail
