I am not far from the Logan Hyperdumb......Hey quick question, would a 10" dob with quality eyepieces be better than a 16" telescope...if I have the chance to get one cheap enough is the size (it will stay put in my backyard) worth it??

Hi Andrew,
I'm just the other side of the freeway at Tanah Merah, less than 1km from the 'dome. I bought a DGM Optics NPB filter after reading a lot of reviews, and haven't been disappointed - they're a very good filter. 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"!
