Description:Plossl eyepieces such as Orion’s Sirius Plossl have become the workhorse oculars of choice for thousands of amateur astronomers because of their excellent image quality, good eye relief, wide fields of view, and affordability. Not to take anything away from your basic Plossls they're terrific but we wanted a line of Plossls that offers even better performance and some upgraded features. Plossls that would appeal not only to the dedicated beginning observer but also to more advanced skywatchers who value exceptional quality.

So we're pleased to introduce Orion HighLight Plossls, an exclusive, premium line of 1.25" Plossl with some noteworthy enhancements.

Like the Sirius Plossl line, HighLight eyepieces offer a generous 50° field of view (43° for the 40mm) and crisp, sharp images. But the HighLights 4-element optics are not just fully coated or multi-coated, but fully multi-coated. That means that every air-to-glass lens surface is multi-layer coated for the highest possible light transmission and better contrast. You see more of those pinpoint star images and more faint detail in deep-sky objects. In addition, the lens edges are blackened for additional contrast enhancement.

The machined aluminum housings of the HighLight Plössls sport a distinctive anodized finish, with grip traction knurled right into the metal. You won’t find this fine touch on any other Plössls on the market. The supple rubber eyeguards shield out extraneous light and fold down for eyeglass wearers.

Like all Orion eyepieces, the barrels of HighLight Plössls are precision-machined to a tolerance of +/- 0.05mm from the nominal specification, so you can be sure of a great fit in your diagonal or focuser. HighLight barrels have a setscrew safety recess to reduce the risk of an eyepiece falling out should the locking setscrew become loose. And of course they are internally threaded to accept filters.

Each HighLight Plössl eyepiece comes with top and bottom end caps for protection against dirt and stray fingertips!

If you have never used Plössl eyepieces before, or you’re using standard Plössls, consider upgrading to premium HighLight Plössls. You won’t find a higher-caliber eyepiece line for the money than HighLights!

Highlight Plössl Starter Set
An ideal upgrade set to replace lower-quality eyepieces, it includes three must-have focal lengths for low-, medium-, and high-power viewing: 26mm, 17mm, and 10mm.

Highlight Plössl Expansion Set
If you already have the Starter Set, or the 25mm and 10mm eyepieces included with many telescopes, this set provides three complementary focal lengths for medium and high magnifications: 20mm, 12.5mm, and 7.5mm.

Highlight Plössl Power Pair
For planetary and lunar viewing, especially, these 12.5mm and 7.5mm high-power oculars will have you discovering new detail. Even if you already use a 9mm or 10mm eyepiece, get this pair to add more magnification options.

I think this e.p is an overall excellent e.p based on my first impressions with it through my xt6 f/8. The fit and finish on it are solid and it is an attractive e.p. Comparing it barlowed to a 7.5 tak LE, 6mm BO/TMB and 9mm t6 Nagler it gave the brightest image of Saturn and I felt the most gratifying view, although it gave the least amount of f.o.v. Stars were sharp out to the last 90% or so. Anyway thats what I think of what probably is an underated line of eyepieces, I am expecting the 7.5,12.5 and 20mm here soon and will give my opinion on them.
After using this in my 10" f/5 I note some edge issues about 3/4 the way out. I have owned a t.v 20mm plossl and it seemed to perform a bit better in that respect.

Orion HighLight Plossl 17mm
I was very impressed with this eyepiece. I own a couple of TeleVue plossls (11 and 15 mm,) that are excellent performers. This is also excellent. I liked the fully multi-coated optics, and just the general feel and appearance of the ocular. Is it as good as a TeleVue? I cant say, but it sure can give it a contest,

I have to admit I was a little disappointed in this eyepiece. The Highlights are suppose to be the top of the Plossl line for Orion but this seemed to fall more toward the middle. I have an 80mm F6 achro, a 102mm F8 APO and a 12.5" F5 dob and used the 17mm in all three scopes. There wasn't much difference from scope to scope, the central 50% of the field was pretty good but even in the F8 the stars started getting soft as you went to the edge. Of course it was more pronounced in the F5 newt.

On a so-so night the Orion was trying to keep up with my 18mm Ultima, but when the skies improved it was no contest. Perhaps I got a poor sample so I'll give it a value of "7" in case other Highlights are better than this one. Fortunately I got it on sale so can't complain too much. As always, YMMV.

The 32mm and 25mm are the best of the Plossl line. Bright images, decent field of view, and good eye relief. When you drop below 25mm, the eye relief starts to get a little short. Below 10mm the eye relief is negligable - to the point where I won't use them even if I won them.

Orion HighLight Plossl 17mm
This is a very good ep. I only had a chance to grab a couple of quick looks through it so I'll hold my vote till later.
However for now I'll give you my first impressions. Mechanically it's beautiful, feels solid and looks pretty. Optically, it seems to hold it's own.
I do own a couple of Televue Plossls, and an Orion Ultrascopic,this ep appears to be in that league. I'm just holding my vote for now until I get a chance to really evaluate it.

I'm new to all this, and was looking for good value in an EP. Some friends have let me borrow pieces to try out. I have a 4.5" f8 and an 8" f5. To me the simpler design of a plossel seems to make things brighter, most noticable in the 4.5". Images are sharp and crisp across the FOV. I track planets like saturn from one edge of the FOV to the other and then adjust back to the other edge. I have not noticed any change in the quality of the image. I highly recommend these to some one just getting started out and want exellent images for a low price. EP's I have tried are Meade "Silver tops", Orion Epic ED's, Nikon. The Highlight's Are definatly The best for the price, out performing the Epic ED which really surprised me.
