Very good eyepiece. Nice and bright image and feels like a good eyepiece, has a premium feel to it. Crisp images.

For the price to pay and even though a beginner in astronomy this is amazing bang for your buck, in the past using such brands as Leica I'm aware of what good optics are like and this really is very good. The 10mm was ordered and it gives fantastic eye relief so for all the poor unfortunates like me that have to leave your specs on the is the very fellow for you, it's quite heavy, very well made and the image is crisp and sharp. As for Flo came across this firm by accident and what a god send they have been with their generously given time, patience and expertise a thing us beginners rely on to make the right decisions in our purchases.

Excellent eyepiece with good wide field and little or no degradation at the edges. Works well in my 4” F/7 and F/9 refractors.

Great fast service from FLO as usual.

Only tried it twice as I ve only bought it and it came with clouds!
However first impressions are amazing!

Really pleased with the performance of the Baader Hyperion. Using it in the Skywatcher 8" Dobsonian. I would definitely recommend the Hyperion.

These two pieces made the viewing experience so much better than the stock eyepieces that came with my telescope.
Tested last night and got great views of Jupiter and Saturn.
Delivery was prompt and items where carefully packaged.
Would recommend FLO and will shop here again.

I have 6 of the Baader Hyperion 68 Degree Eyepieces (24mm is the only one I do not own) and I am very happy with all of them.
I like that they can be used with both 1.25" and 2" focuser drawtubes. Also they provide very nice views and I have a T2 ring which makes it very easy to do eyepiece projection photography.

this my 2nd 17mm hyperion eyepiece the first one got ruin when i tried to fit a fine tuning ring and got dust inside when i tried to rub it off i manage to scratch the lens,be careful when you unscrew it make sure you're in a dust free environment,if you get dust inside it's a nightmare to remove, having said that it's a superb eyepiece i've got the baader hyperion zoom eyepiece easy 5 stars worth every penny

I purchased the Baader Hyperion 13mm on Wednesday 18th 2018.
The speed and service was very fast and professional, i got it the next day.
The only downside is that i haven't had the weather to use it yet to give a review, overall though i can, the lens is definitely in a class of its own when i compare it to the Celestron Plossl's i own, its a giant at the side of them and quite weighty too.
The Baader lens just feels right and comfortable when handling.
It also has a Quality look about it.
As it stands right now, it is in my Skywatcher 300p Flextube just waiting for its first look at the night sky, here's hoping we get a clear one.
Will update more once used more,

I have a 13mm hyperion ,quite a versatile size as you can unscrew the turret and use as a 24mm 2" ,or buy appropriate tuning rings and adapt to a 9mm or 11mm eyepiece or buy a t-adapter and fix your camera onto the end .well made piece of kit .would recommend
