I am looking for a quick review of the Tele Vue Radian 10mm eyepiece. Is it just as good as the 14mm?

i would think all Radians would equally be of the same quality... but, not to go off your question, but i bought a 10mm Axiom (for less than a Radian) that i am very happy with.

There ya go!
Didn't I tell you they get addictive? 
With the Radians, it seems like you either love 'em or hate' em...
I started with a 12mm, now I've got 6 of them... (yes, ouch my cr.card!)
and I find them all excellent (not only because of eye relief...)
I have TV Plossls, Nags, Radians, Vixen LVW's and UO Orthos,
the Radians are my favorite eyepieces, and they get a "Wow!" everytime I use them, on any kind of subject.
Anybody know of "bad" TV eyepiece anyway?

I consider the 10mm better than the 14mm. The 14mm is great, but I see a little less aberration control off-axis than I do in any of the other shorter focal lengths up to 4mm (I don't have the 3mm). So the 14 is not quite as "tight" as the others for me. That being said, if you like your 14mm, then you will really like the 10mm 
Actually, I think the 10mm is really quite excellent. Although I use the 6mm and 8mm most, whenever I put the 10mm in the slot I always say "wow" and am just really please with the view it shows.

I would agree with the other posters - if you like the 14mm you should like the 10mm. I use both regularly and find them excellent for deep sky and solar system observing.
kaaikop also makes a good point. Personal preferences aside, I have yet to see a TeleVue product I wouldn't mind using.
Clear skies,

The 10mm Radian is one of my favorite med-high power EPs. Very comfortable ER and super-sharp. I also have some shorter Radians and they are also equally nice to use.

The only Radian I have is the 10. I love it. Wonderfull image and comfortable to use. I bought mine years ago. When Televue had their sale a while back I bought a second for my binoviewers. They're a little on the heavy side, but they make great binoviewer eyepieces.

Listening (i.e., reading) to the comments pretty consistently made regarding how heavy Radians are, it often makes me wonder why they did this. If you examine them, all this weight comes from the milling (or lack of milling down) the chromed brass barrel. I often wonder if this was done to convey quality (since lightness often conveys less quality for small packages to many consumers), or if it was done for some thermal considerations within the eyepiece, or if it was just plain less costly to do it this way vs using some other material for the chromed barrel.

I had a 10mm Radian and the views were excellent in my Mak. I just couldn't get on with the instajust eyeguard thhough. If you can, go for it.

Agree with you on that Insadjust thing. For a while I took the eyeguards completely off of my Radians. Recently though put them back on but tightened up the spring in them so now they don't slide up anywhere near as easily as before. So now don't mind the Instadjust.

Owned the 12mm & 10mm Radians at one time.
A friend has the 14mm, but only looked through it a couple times through his scope. It looked good, but can't really comment further.
Thought the 12mm gave a crisper image than the 10mm, maybe (maybe not) just because of it's lower power? I found the most comfortable position of the Instajust was to pull it fully up & roll the rubber eyeguard down. Stars remain sharp to the edge, but the image seems a little dim for some reason? & didn't care for the color on bright objects at the edge of FOV. Overall very nice eyepieces though.
