What Will I See?

Ah, the drama of it all!

I have my Celestron Nexstar 6 - and am quite delighted with it. No dramas with an outback trip, apart from issues with SA local time, full moon, cloud and rain............!

With developing enthusiasm (read, like, that I am seriously hooked!), I need to learn stuff about eyepieces. I have the standard 25mm (50° fov) and a Hyperion 8mm (68° widefiled), and I am thinking of adding to these.

Questions:

What can I expect to see comparatively at, say, 10mm with the various types that I see discussed - planetary, Plossl, widefield, etc, using Jupiter and its moons as a sample target? Currently my 25mm shows Jupiter and four moons within about 2/3 fov diameter; the 8mm just fits all in; scope focal length is 1500mm.

Do widefields loose detail of planets when viewing same? (ie would a tighter fov provide better detail?)

What specific uses would be best assigned to what ep types?

Does a dissertation exist that may provide me with the 'stuff' that I need to know on this topic?
