I should have also mentioned that the introduction of a filter into the optical train has always made planetary images less sharp. They may enhance some details, but at the great expense of resolution.

I'm interested in the 82 degree eyepieces for planets, doublestars, and planetary nebulae. They are on sale right now and I may buy one soon. Thanks.
