Good optics; well made; good FoV; good ER. Bought with Starguider 25mm EP and Barlow. All at good price for such good quality

An excellent upgrade from my standard eyepieces that came with my 127 mac!

A solid eyepiece that is punching way above it’s weight. Good clear image with no ghosting or kidney beaning that i could see. I will be buying the rest of the range very soon. These are the best upgrade from the supplied eyepieces that come with most telescopes.

Eyepieces arrived promptly and where well packaged.
I purchased the 8mm and 15mm to supplement my standard eyepieces that came with my Skywatcher 130m. They where more substantial than expected and are very well made. Once I started to use them I was not disappointed. Looked at Jupiter and Saturn with both eyepieces and could define the bands on Jupiter.
Started with the 15mm on Saturn which was great but once I got the 8mm on the job, well......all my days. I was able to pick out Titan and Dione. I was ecstatic.

I would recommend these eyepieces to anyone looking to upgrade on a budget as they punch well above their weight.

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!)

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 .

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!

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.

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.
