TeleVue Plossl 8mm
The contrast and sharpness are very good. Very tight on eye relief, however, with no sharp field stop and the field of view is quite small.

TeleVue Plossl 8mm
Nice sharp eyepiece. Gave slightly higher contrast in an f/5.8 APO telescope than the Brandon 8mm. Best readily available 8mm planetary eyepiece, the Clave 8mm is the only better one.

TeleVue Plossl 8mm
I had a TeleVue 8mm Plossl exactly one evening before I sold it. I had a used, semi-beat up inexpensive Meade 9mm ortho and thought I would treat myself to a TeleVue Plossl. The field of view was greater on the Meade ortho. Even taking into account the 1mm difference in focal length, the ortho still had at least as good of a field of view performance as the TeleVue, if not better. The Meade ortho was also quite comfortable to use, while the TeleVue Plossl was quite unpleasant to use due to eye relief. Sharpness of image was approximately the same between the two different eyepieces. This is the first TeleVue I have ever specifically not liked.

TeleVue Plossl 8mm
I purchased a TV 8mm plossol to fill the whole between my 7mm and 9mm U.O. Ortho's. I have used the eyepiece extensively now and love it. Images through the eyepiece are exceptionally crisp and very pleasing. There is no edge distortion and absolutely no color at the field stop even when viewing the moon.

Some eyepieces just feel right. For some reason when I use this eyepiece the clarity is striking.

Eye relief IS very tight if your trying to take in the entire field of view. I I have found, however, that objects being viewed at such high powers do not usually require the observer to see the entire field of view.

Despite tight eye relief I find the clarity of this eyepiece far out weighs the eye relief issue. Of course these types of things vary from observer to observer.

I subtracted 1 point because of the tight eye relief. Highly recommended for those not bothered by the eye relief issue.

TeleVue Plossl 8mm
Not for those with long eyelashes...but great in a (perfectly collimated) 10" dob for planets and planetary nebula. Contrast is pretty good too.

TeleVue Plossl 8mm
Excellent high power planetary eyepiece. Eye relief is short but still usable without glasses. Sharp, flat field with excellent contrast. Fills the gap between my 7mm and 9mm Pentax SMC orthos quite well and that puts it in exclusive company.

TeleVue Plossl 8mm
Very good eyepiece. I use it often on the planets and the moon. My only complaint is the eye relief.

TeleVue Plossl 8mm
A 7 only because the ER is terrible. In order to see the field to the field stop, you have to really push down on the eyepiece with your eye. Other than that is is sharp to the edge with good contrast.

If TV could add 2mm to the ER they'd have a really great ep......

TeleVue Plossl 8mm
There is no way to design a 4-element Plossl with an 8mm focal length that will have more than 6mm of eye relief. One could design a 4 element 16mm Plossl with an integral 2 element Barlow lens and have a 6 element 8mm Plossl with about 13mm of eye relief but what's the point? Fewer elements = better planetary eyepiece. No short focal length eyepiece that does not integrate a Barlow into the design is going to have much in the way of eye relief. Short focal length Plossls and orthos are prized for their "purity" of light transmission. They add nothing to the image and take nothing away. Short eye relief is a minor inconvenience to those of us who seek the best possible image fidelity. If you desire more eye relief, there are plenty of options available but they are usually more expensive and often have an effect on the purity of the image being magnified.

TeleVue Plossl 8mm
I am satisfied with the clarity and sharpness of the TeleVue 8mm Plossl. The field is sharp edge to edge. The notch machined in the barrel gives extra security for eyepiece retention. The planetary performance of this eyepiece is excellent.

I agree with the opinion stated in the prior comment. It is puzzling how experienced users can complain about eye relief on a Plossl eyepiece that has less than a 10 mm focal length. Hopefully we all agree that the eye relief of a true Plossl is determined by physics. Reviewing previous opinions it seems that the level of satisfaction with this eyepiece may have more to do with users’ acceptance of the physics that govern optics than the actual quality of the eyepiece.

I rate this eyepiece highly because of the unique value provided by this high quality moderately priced eyepiece. For a Plossl price many observers will find the view rivaled by few premium eyepieces. Caveat: The eye relief is tight on this eyepiece. If you must wear glasses you will probably need to consider a more expensive design for high power use.

TeleVue Plossl 8mm
A very nice eyepiece. Perhaps because it was one of my first eyepieces, the eye relief, although tight, doesn't really bother me. Good, sharp views. I spent a lot of time comparing the view with my 9mm uo ortho, both with my C102 HD, largely on the moon. Sharpness seemed about equal in both scopes; obviously the ortho has a somewhat smaller field of view, but I didn't find that bothersome. The one difference I did notice was that the TV presented a slightly "warmer" image of the moon than my uo ortho, which seemed to give me a starker, perhaps slightly more contrasty image. It was noticeable but fairly subtle. I prefer the image through the ortho, but others may disagree.

Nice eyepiece

sharp but poor eyerelief.

noticeable better than 7.4mm and 10.5mm older plossls. noticeably worse than a 6mm and 10mm zeiss orthos with more colour less contrast similar sharpness.

TeleVue Plossl 8mm
Oculare eccellente.Con il mio C8 le immagini planetarie sono molto contrastate e assolutamente prive di riflessi interni. Le immagini sono prive di riflessi interni anche se si accoppia una barlow tele vue.

TeleVue Plossl 8mm
Outside of possessing tight eye relief, the Televue 8mm Plossl is a fine ocular. I used it on my 10" f/5.6 Newtonian and was graced with some great views of Jupiter. I also tested the eyepiece out on a friends 12" f/5 Meade LightBridge Dobsonian and was floored by its performance. Barlowed (2x) on the 12" LightBridge, the Televue 8mm yielded a power of 381x. Looking at Saturn at this magnification there was no hint of coma, or any noticable aberrations whatsoever! The image bright and crisp. Both Cassini and Enkes divisions were easily discerned, along with good temporal belt detail. The view was glorious.

This ocular is indeed one of my favorite high power units. The green coatings seem to aid in revealing true color. Contrast is good and the 50 degree field is flat to the edge. I got mine used for a great price of around $50.00, but they are well worth the regular $85.00 price. I recommended it highly.

Clear Skies, Forever!
