I'm thinking of getting eyepieces for an ED80 and ED100 for astro viewing rather than astro photography. Question time.
2" or 1.25" - which would you choose and why? I was thinking the 1.25" are much cheaper and would be fine for just general viewing?
What length eyepieces? I understand the length of eyepiece to scope focal length gives a magnification factor. What one or 2 magnifications would you think would be good for general purpose? Would you get one for widefield/nebulae/constellations etc, and one higher mag one for planets/moon? I have no feel for what mags will yield good results.
Also thinking of a prism for viewing. Any tips or pointers on that? 2" vs 1.25"?
