About this product

Model:  bst_sg_15
Part Number:  SP10854

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. 

FEATURES

  • 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.

15mm 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 15mm has become my main eyepiece, giving clear general views of planets and the moon and wide enough views for most DSO's. The range of colours of stars in open clusters is much clearer.
The wider field of view (60deg) makes for a much more "immersive" feel to the views too.

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!)

Fabulous eyepieces
Wednesday, 22 September 2021  | 

I bought 2 bst eyepieces 15 mm and the 18 mm to fill in the gaps between my more expensive eyepieces and wasn’t disappointed Crystal clear and de be honest I could see no difference between them and my televue delite eyepieces , I would strongly recommend buying these and saving yourself some money on the more expensive brands. The pretty lightweight but still feel like a quality item .

Good Mid Range Eyepiece
Sunday, 5 July 2020  | 

I tried this against a Meade Super Plossl 15mm eyepiece. The performance on the lunar disk was very close (excellent) between the two eyepieces, but the BST StarGuider ED 15mm wins by a whisker due to the wider angle!

The best eyepice that I have had.
Tuesday, 23 June 2020  | 

I am very happy with this eyepiece of 15mm. I had read a very good reports of this eyepiece and I have been able to verify these opinions. Vision is clear and sharp. The eye relief is great and very useful for people with glasses like me. It is a bit heavy but without problems for my small telescope Newton Orion 100 / 400. I am delighyted with this eyepiece. I will not hesitate to buy BST Starguider again in the future.

Worth its cost.
Thursday, 4 April 2019  | 

This is my first branded eyepiece so unfortunately I don't really have that much to compare it too. The build quality is obviously much better than the 2 eyepieces that came with my skywatcher 200p, the twist up eyecup is also really nice and feels like it'll last a lot longer than the flip up equivalents on the standard eyepieces. Image quality seems fine, feels about on par with my standard 25mm eyepiece, maybe slightly better, slightly larger FOV is also nice. Eye relief doesnt feel all that great compared to my 25mm, can be trickier to observe with. Observing bright objects can create a glare/reflection at certain angles which can be annoying.
Overall though i would say these eyepieces seem like they are worth thier price, although i probably wouldn't replace my standard eyepieces with BST equivalents, they are good cheap alternatives when it comes to buying eyepieces to fill the gaps in your collection.

Yes. Definitely :-)
