TeleVue Radian 6mm
I've had this ep for a couple of years, and I can't think of any shortcomings at all. I am absolutely 1000% satisified. The eye relief is a nice 20mm, it has a 60 degree f.o.v. and my best view ever of Jupiter was through this eyepiece.

TeleVue Radian 6mm
I have my 6mm TV Radian for 6 months now. There's not much for
to add. After my fateful encountered with the Vixen 5mm LV (45d
FOV version) that I quickly returned, I'm happy as a clam. It's
sharp to the edge, bright, and contrasty. There's slight chromatic
aberrations near the edge of the FOV, but I don't usually concentrate
my view there. It's wide 60d AFOV makes you feel like part of the
scene; it's 20mm eye relief allow me to view the planets very comfortably
for a long period of time. The entire 4 Jupiter moons fit in the FOV.
This is by far my most-often use planetary eyepiece (the other
being the 5mm Tak LE) in my TV-102 AP0. This is also my favorite
eyepiece for high-power viewing globular clusters such as M13 and
M22. M57 without nebula filter remains bright with the eyepiece.
It also works great with other DSO as well. The moon is great too,
but can't beat the 4mm TV Radian when it comes to giving the feel
of a lunar lander flying by.

Oh, did I say I love the Insta-adjust eyecup ;-), seriously!

Highest rating!

Very sharp eyepiece. At 167x, Cassini division on Saturn an easy target. A few bands visible, as well as 3 or 4 moons. More detail is revealed in the Radian than in my Burgess/TMB Planetary.

TeleVue Radian 6mm
I've had this Radian (my first) for a couple of months now, It's used primarily with my 10" f/4.8 dobsonian which gives it 200x. I wasn't sure what to expect, but I can honestly say that this eyepiece blows me away. What I especially like about it is the nice eye relief, coupled with the 60 degree field of view, sharp across the whole field. My nearest eyepiece in that range is a 7 mm. Orion Ultrascopic. The views of Jupiter and Saturn are equally fine on both, but the Radian's eye relief and wide f.o.v. make the viewing so much more comfortable. This ep also is great on globular clusters. Light throughput seems equivalent to the Ultrascopic, both are excellent. I mentioned previously this was my first Radian, it won't be my last. Yes, they are on the expensive side, but you can pick yours up used like I did for $185.

It provides superb views of Jupiter and Saturn (on calm nights) with my 8" f/10 LX200 Classic.

I wasn't really very excited about the Radian EP's when they were first announced by Televue. I had my big collection of Naglers, Panoptics, Plossls, Konigs, Orthos and more. I just wasn't sure if Radians filled any need in my collection. Then I had an opportunity to pick up a 6mm Radian for a good deal. What a pleasant surprise! I am now convinced that for EP focal lengths shorter than 10mm, nothing comes close to the Radian design. This EP is an absolute pleasure to use.

TeleVue Radian 6mm
One of the best high power eyepieces I've used. Used last night with Saturn and Jupiter. With a Meade 10" LX50 and a f6.3 focal reducer, I clearly was able to see the divisions in the rings (Cassini's division) and some striping on the planet. Very sharp with excellent contrast. WOW! I've used it on the moon as well with wonderful results. The large eye relief makes it easier to use then other 6mm EPs. The weight is a little on the heavy side in comparison but not so much that I've ever had a problem with it. I haven't really experienced any reflections using it in the SCT as well.
Great eyepiece. Highly recommended.

The lunar view alone justifies owning this eyepiece.

The 60* wide field is clear to the edge with ortho sharp images. Brightness is incredible. When a 7 element ocular can rival simple 4 element orthos it is clear that great design, materials, and coatings are at work.

I've only recently bought this eyepiece, and it has given me simply the best view of Saturn that I've ever seen (333x with 140mm Mak Cass). The background sky was as black as I've seen it, the image was sharper than ever and detail was much more prominent. Cassini was crystal clear and the divisions obvious and all this on a night of below average seeing.
There was minimal light scatter around the planet as expected (more obvious with averted vision), but no worse than a 6mm ortho that I compared it to. No ghost images or reflections were seen. I can't wait to try it out on my other scopes.
At last I've found a high power eyepiece that I am completely happy with, this one will stay in my accessory case for a long long time along with the other Radians in the set that I've just ordered.

A wonderful eyepiece! I found the large eye relief to be very comfortable - something that is definitely important to high power viewing. This was the pushing the limit for my C11 at 467x magnification, but it held up well in spite of moderate seeing on doubles and lunar views. Will have to wait a few months to test it on Mars and Jupiter. Detail and ease of sharp focus are most impressive. Complete sharpness edge to edge, and a nice wide field of view. My Nagler 7, LV 9, and Barlow will likely now collect dust on the shelf.
