I also have some OIII filters which are pretty good, but the DGM NPB tends to give a less "green" overall effect. I had it out last night looking at Orion and the filter made a world of difference. I can't comment on the eyepieces vs larger scope issue - I've currently got an 8" dob, and my 16" dob is arriving (hopefully) in the next few weeks, which will certainly make things a lot brighter/bigger, but I haven't tried enough eyepieces to make an informed decision regarding the benefits of more expensive EP's over larger aperture. A 16" dob at <F5 is probably going to warrant some better eyepieces + coma corrector to get the most out of it. You sound like you've got a pretty reasonable start with the Nagler though! I normally use a Baader 8-24mm zoom, which saves me having to swap eyepieces all the time, and although it's not in the televue class, it's a lot better than the standard plossls you get with a scope. As either Malcolm or Allan said, once you've seen Jupiter and Saturn at high mag, there probably aren't a lot of other objects that justify an expensive high mag eyepiece unless you've got super seeing conditions all the time. Yeah, we should catch up once one of us has a 16"!

Wow! 16" will be a big step up from an 8" indeed! Man would love to see the view through that! It's funny as I was eyeing off a second hand 16"and moving my 10" on!! Thanks for the filter advice, I will hunt one down I think. By the way do you have your (or will you) have your 16"set up in a permanent spot? Do you star gaze often? What objects or things do you view most often or what inspires you with astronomy? To be honest I haven't seen much yet but then again I am still learning where things are and how to use my equipment, although I don't like my dodgy eyepieces that came with my Skywatcher 10"....Logan seems to be not too bad for viewing..hopefully a good sky tonight!!
