About this product

Model:  Vixen_NPL-3
Part Number:  X000325

The Vixen NPL series are classic 2-group 4-element Plossl eyepieces that offer higher performance than the majority of eyepieces supplied with telescopes.  


  • Fully multi-coated optics.
  • 20, 25, 30 and 40 mm eyepieces feature twist-up eyecups. 
  • Threaded nosepiece accepts astronomy filters
  • 'Safety undercut' milled into the nosepiece to prevent the eyepiece falling out of the focuser.

Note to spectacle wearers: Plossl eyepieces with 15mm and longer focal lengths are good choices for spectacle wearers but for shorter focal lengths the Celestron XCel LX series have greater eye-relief so are better suited.

Great budget Plossls
05 January 2022  | 

I've got some nice eyepieces for my scopes but they cost a lot more than these NPLs. Picked these in 30mm, 15mm and 8mm to compliment a small travel setup and they are very impressive. The problem with traditional eyepiece designs such as Plossls and Orthoscopics is the short eyerelief in the shorter focal lengths. I don't know about the 6mm and 4mm but the 8mm NPL is surprisingly easy to look through. They all have a genuine 50deg AFOV and are sharp around the field edge. Stars are crisp over about 80% of the FOV which is impressive considering their low cost. If wanting to upgrade from or add to the eyepieces that came with your starter scope and you're wanting to stick with traditional designs that use fewer lens elements, then these Vixen NPLs should be considered. If you need to wear glasses whilst observing ignore all of this and go for an eyepiece design that offers greater eyerelief, the BST Starguiders are a popular alternative.

Much better than expected!

I was after a Plossl EP just for low mag star hopping and relatively wide field views, but the 30mm NPL is so much more than this! Contrast is great, images are pin-sharp across the FOV and eye relief is tremendous - nearly an inch on the 30mm.
I'm sure the actual FOV could be improved upon, but that's it for negatives!

Vixen NPL 30mm
12 March 2021  | 

I wanted a very wide FOV 30mm eyepiece with good eye relief, the guy from FLO explained why my original expectations could not be met and this was one of his suggestions. It is a massive step up in both build and visual quality over the the eyepieces that came with the telescope, also much more easy and comfortable to use. I know the term, “it’s like looking out of the window of a spaceship”, is over used but that’s what it feels like to me. For info Telescope is Celeston 5” SCT.

Well made and far better than basic one that came with telescope. Eye relief tight but manageable. Good on moon and planets.

Not an expert on eyepieces but this is so much better than the stock eyepiece that comes with Skywatcher telescopes. No hesitation in recommending. Great service from FLO.

30mm npl

Definite upgrade from usual 32mm brands, sharp and contrasty over full fov in both f4.9 Star Travel 102 and f10 Celestron 8se, twist up eyecup very good for long eye relief.

In Mak 127 very impressed.

Orion Nebula and trapezium were very well presented by the 30mm version of this EP. Nice and sharp and good contrast despite the sky beginning to show signs of dawn.
It was purchased to give a wide view whilst aligning but it was so good it stayed put for most of the session.
Be interesting to see how it fares with my Newt at f4.7 ???

Cant fault this 25 mm ep for the money. First time out i was allready seeing far more than my stock ep,s. Infact i didnt even get them out. I used this 25 and a 2x barlow. So much better

Amazing quality for a low price
11 June 2014  | 

I bought the 8mm one to get better views of planets, the difference i noticed right away was amazing compared to the 10mm supplied with my skyliner 200p. ring separation on Saturn was very crisp and Jupiter showed in great color and very easy to see the color banding of it. I will defiantly be ordering more of the Vixen NPL range after seeing first hand how good they are
