Gary A, I don't know where to start with your comments. Firstly, eyepieces are like scopes, no one type will do everything really well.
A decent Plossl will produce good planetary images, just a gnat's
whisker less sharp than eyepieces designed for the purpose, such as orthoscopics.
Secondly, fine detail on planets is mostly very elusive, and is only
visible on occasions when the planet is high in the sky and the seeing
is unusually good. Thirdly, your scope is a good all round one, but refractors and Maks are better for planetary work. Even Newts are marginally better, having smaller central obstructions.
Lastly, nebulae are by definition nebulous, and therefore don't usually
present sharp images, with the exception of planetary ones.
I suspect that you are expecting too much from your scope.
Everything Steve just posted is spot on.
