Televue Everbrite Diagonal
Excellent Diagonal, Light transmission and sharpness is just about perfect. I only gave it a 9 out of 10 due to their also being Silver Diagonals with dielectric protective coating that has the same high reflectivity but with less scatter...never tried one but sound impressive. This Everbright unit is well baffled, built like a tank and a noticeable step up from the old enhanced aluminum unit it replaced.

Televue Everbrite Diagonal
With quality like this a standard has been set for 2" diagonals. Superb craftmanship combined with a dead on collimated optical flat of excellent optical quality with a very good 1" 1/4 adapter. I've tested several 2" diagonals and this is one of the very few that is actually perfectly collimated. Great product Televue!.

Televue Everbrite Diagonal
I have the relatively unusual position of getting this as a gift. I did not seek to replace my 2" Lumicon High-relectivity diagonal, but I thought I would try it out for comparison purposes. I'm SOOOOO glad I did. The threading in the extension tubes (versus shiny anodizing in the Lumicon), the ulta-flat black in the housing (vs. shiny anodizing in the Lumicon), and the slightly shorter mirror housing extension that allowed the diagonal to actually fir within the fork arms on my SCT, seems to make it a winner. Internal reflections are gone. And the diagonal is closer to the perfect 45 degree angle than the Lumicon was--after careful collimation on a star, the Lumicon seemed to show some astigmatism, but the Televue exhibits none. This is quite an improvement on the Lumicon, which in turn was quite an improvement on the Orion 2" before it. Only two minor complaints keeps this from a perfect rating--the screws that hold this diagonal in hit the lip of the machined retention groove instead of the flat area, so tightening the screws to secure this to the scope forces the diagonal away from the 2" adapter tube (I cured this problem by countersinking slight depressions at these points); and the eyepiece tube is a little too short to allow me to put some filters on the ends of eyepieces like the Meade 14mm and insert the eyepiece all the way (the filter hits the mirror). This is not a problem with all filters, just some, and you can easily fix it by adding a spacer ring to the eyepiece to lift it slightly out of the tube. Other than these 2 very small gripes, the performance is stunning. By those standards, this is a bargain. Recommended. Highly.

Reply:  Stunning???  I bought the 1-1/4 version and a Celestron stock prism diagonal that it replaced is very close in performance.  The everbrite is a tad brighter, but shows more light scatter without the MgF coatings of the prism...  The mechanics are better for Nagler eyepieces (big surprise here) and it has the recessed safety notch: but in hindsight, the 200 bucks would be better spent on another quality eyepiece.  Based on your review, I'm assuming that the Lumicon version really sucked.

I'm new to the sport, but having this diagonal was recommended. Tried it on the Outer Banks of NC over the weekend. Compared to the standard Meade w/the LX 90, this Tele Vue was worth the money for the viewing pleasure! Buy one and don't look back.

Only a 9 because retention groove is not properly positioned for my holder's screws (they hit exactly on the lip of the groove). Otherwise, simply the best diagonal there is. Images are better, and contrast better than with any of the 3 others I've owned in the 2" size: Orion, Lumicon, Meade.

Televue Everbrite Diagonal
I use the 2" version with my Takahashi TOA 130 ; I initially purchased the Lumicon "Lumibrite" but found that some of my eyepieces were difficult to remove without disturbing the alignment of the telescope. Almost all of my EP's are Televue , so I fugured that the TV diagonal wwould be better.
The pleasant surprise was the the Televue diagonal was far better in every aspect : optics seemed sharper , and the mechanical fit and finish superb. I highly recommend this diagonal.

Expensive but like everything else in the hobby, if you want the best you pay a premium for it. Background sky is definitely darker when using this diagonal when compared to a standard Celestron diagonal that I had been using previously and scatter around bright objects is reduced.
No doubt about it, this diagonal provides more pleasing views and so for me it is worth the purchase price.
Identical performance to a friends Maxbright, but I'm not a fan of the compression ring system and so bought this, I haven't been disappointed.

Televue Everbrite Diagonal
I can't see the difference in brightness. There is a small but noticeable improvement in contrast and sharpness due to reduced scatter compared to generic diagonals. Very solid construction. Only possible problem is that it is very heavy - smaller scopes might be difficult to balance. I doubt that many would notice a brighter image except in larger aperture scopes, but I think the reduced scatter makes it worthwhile. I haven't seen an AP Maxbrite, I'd love to hear a comparison.
