UO eyepieces will be just as good on DSO's as they will on planets. The only thing you wont get is a wide apparent field of view (AFOV) that is needed for some large DSO's (very few). However most DSO's will fit into the field of say a 25mm eyepiece and your 6" telescope but a larger AFOV helps if you do not have tracking.
An alternative to the UO orthoscopics would be the Meade 4000 series Plossl eyepieces which are well priced or if you can afford it the Tele Vue Plossl eyepieces.
