[icytailmark (Mark)]

what would be the best eyepiece for my 12" SW dob?

Im tossing up between 26mm Nagler Type 5, 35mm Panoptic, or the 21mm Ethos.

I want to be able to look at Galaxies,open star clusters,nebulas, and any other DSO's thats my telescope can find.

I currently have a pentax 7mm XW, 13mm Nagler type6 and a 20mm plossl that came with the scope.
