My personal eyepiece preference is a wide-angle Erfle (28 millimeters)
that (believe it or not) is (or was) manufactured by Edmund Scientific.
I use it with a mead 8" F6 reflector and get excellent wide-field views
(almost 1 degree field) of deep-sky objects. The only object it is not
ideal for is small planetary nebula of under 1 arcminute in diameter.
For clusters, diffuse nebulae and galaxies it is great! I have reached
13.5 magnitude (under excellent conditions) with certainty (ie no
averted vision).
It is also great for variable star work, with a field large enough for
comparison stars and makes 'star-hopping' location techniques good also.
