About this product

Model:  bst_sg_8
Part Number:  SP10852

Please note BST StarGuider ED eyepieces are occasionally branded 'Astro Essentials'. 

Remarkably high performance-per-£! 

Features include two ED glass elements and fully multicoated edge-blackened optics for excellent colour, enhanced contrast, high light transmission and minimal ghosting. 

The six-element / four-group design minimises field curvature for a nice flat field, even when used with telescope f-ratios as low as f5. 

Modern twist-up eyecups, 16mm eye relief and 21mm diameter eye-lens makes them comfortable to use, even when wearing eyeglasses. 

The tactile rubber grip and milled indentations make them easy to handle in the dark and the 1.25“ nosepiece includes a safety undercut so the eyepiece is less likely to slip out of the focuser. The 1.25” nosepiece is also threaded to accept 1.25“ astronomy filters. 


  • Two ED glass elements minimise chromatic aberration. 
  • All air-to-glass surfaces are fully multicoated for high contrast, high light transmission and minimal ghosting. 
  • Blackened lens edges reduce internal reflections and further increase contrast.
  • Six-element / four-group design minimises field curvature for a nice flat field. 
  • 16mm eye relief (suitable for spectacle wearers). 
  • Large 21mm eye-lens diameter for comfortable observing. 
  • Convenient screw-out eye cups. 
  • Tactile rubber grip for easy handling in the dark. 
  • 1.25“ nosepiece with milled safety undercut. 
  • Accepts 1.25“ astronomy filters. 
  • Suitable for use with telescope focal-ratios f/5 and above.

Bst starguider 8mm, skywatcher 130p heritage.
Saturday, 1 October 2022  | 

Great value eyepiece, feels like a quality product. Very nice views from it combined with a skywatcher 130p heritage. Great eye relief and FOV. Comfortable stargazing.

Excellent quality

Very impressed with this eyepiece, its that good that I will now be getting the 12mm eyepiece.
This BST eyepiece is a vast improvement over my skywatcher eyepiece which came with my scope, the weight of the BST starguider is probably three times heavier then my skywatcher eyepiece, but this BST is very well made and looks quality.

BST StarGuider 60 8mm ED Eyepiece
Friday, 28 January 2022  | 

Prompt service and delivery - as always from FLO. I have only used the eyepiece once since delivery- and that briefly in quite bright twilight - due to the enclosed clouds! However the cloud bands on Jupiter and the Galilean moons were clearly seen in a 80mm refractor. The nebulosity and stars within M42 were also easily seen. The eyepiece seems of a high build quality and is comfortable to use.

BST Starguider Ed 8mm
Tuesday, 30 November 2021  | 

Well put together eyepiece that gives a decently corrected image on axis and out to about 80% of the field. This 8mm along with my 5mm are great for planetary viewing . Comfortable twist up eyecup. This range of eyepieces are a very good stepping stone from the ones supplied with most telescopes

8mm BST Starguider with Sky Watcher 200mm/8" 1200mm dob.
Thursday, 23 September 2021  | 

I spent several hours enjoying this scope with the 10mm and 25mm supplied eyepieces then, during weeks of cloudy skies, I ventured down the rabbit hole of selecting some new eyepieces.
The Stargazers Lounge forum was incredibly helpful (thanks to FLO for sponsoring it) and led me to getting 5mm, 8mm and 15mm BST Starguider eyepieces, (giving 240x, 150x and 80x with this scope. (I later added a 32mm plossl for low magnification.)

The difference is staggering! To my eyes the images are very bright, sharp and show very little distortion.
This 8mm is ideal for close up views of planets (seeing the Cassini division in Saturn's rings for the first time was a real wow moment!), details on the moon, splitting doubles and to view detail in DSO's.
The magnification (150x) is very useful while still being easy to guide with a standard Dob base.

For me, and for this scope, they have been an excellent (and inexpensive) upgrade. I thoroughly recommend them.

FLO's service, speed of response, quality of packaging and choice of courier are all excellent. (I live in France - express delivery took just 3 days!)

Excellent upgrade over standard eyepiece
Wednesday, 22 September 2021  | 

Recommended as a first purchase after buying my telescope. An excellent improvement over the standard eyepiece that shipped with the Telescope, very good value. I would buy the same brand in future.

Thankfully the guys at flo recommended these e/ps over a dearer type that i was interested in, usually with shops its the other way round. Nice to deal with an honest business. The e/ps themselves are very good quality and very well priced, they also barlow well. So good good every way. Goods came well packed and very prompt delivery. i will be ordering more to add to the set. thank you flo.

The best value for such money

Pretty sure there's no better eyepiece for this price-range.

It's optical quality, FOV (field of view) and ER (eye relief) are unbeatable in this price-range!

Q1. But aren't these the same as ........ ?

Probably... BST (BarSTa) Starguider ED eyepieces are available under a number of brands but we source them with their original factory name.

Q2. Are these noticably better than the 10 & 20mm eyepieces supplied with my telescope?

Yes. Definitely :-)
