James,
You don't really see further. You see brighter.
Deep Space objects are in your scope but very faint or picking up no light at all. It is a lot of money to pick up a lot of light.
Whereas something like a $29 scope can show you Moon, planets, nebulas and others quite well for a long time.
I waited 20 years to step up to a bigger scope. I had great views with my 4.25" home made reflector.
Get used to the sky for a year or two in your scope and then consider moving up or you will turn into Striker
EDIT: That's not fair. You changed from scopes to eyepieces while I was typing my reply.
What is written on your EP's. If it says 'Series 500' they are not the greatest!
