With a wide angle of view and generous eye relief, the Alpine Astronomical Baader Hyperion 68° 8mm Astronomical Eyepiece delivers the performance that avid amateur astronomers demand for viewing and imaging. Engineered with an 8-element/5-group lens design, the eyepiece features Baader's proprietary 7-layer broadband multi-coatings to maximize light transmission across the entire visual spectrum with true color rendition and without the green tint and halos common in many astronomical eyepieces.

Baader made this eyepiece with a unique modular design that allows it to fit into standard 1.25" holders and accessories with the ability to remove the primary snout and have it fit into larger 2" holders. Since one of the lens groups is in the 1.25" snout, when it is removed it changes the focal length without changing the brightness or long 20mm eye relief. The focal length can also be changed through the use of compatible filters�allowing you to customize the magnification yield based on your optical tube assembly and need.

The eyepiece comes with a fold-down rubber eyecup for use with or without eyewear, and the eyecup can be completely removed to reveal a set of two threads. These M43 and M54 threads allow T-rings and other adapters to be mounted for direct connection of imaging systems for afocal and projection astrophotography techniques. This model is not parfocal with other Hyperion eyepieces.

Cute and comfortable!
Size: 6.5, Color: Chestnut
These are cute and surprisingly comfortable! My arches feel supported and the soles don’t feel as block-like as other platform style sandals! Things to note: The footbed liner is not made of suede and is a little slippery. It’s like a neoprene liner which was unexpected for an Ugg shoe. Also, I only intend to wear these sandals as slides (a la Birkenstocks) so the “adjustable” Velcro strap over the top part of the foot seems useless. It doesn’t snug the top down at all, functionally speaking it is only to wear around the back of the ankle. Maybe this matters to someone thinking they could tighten the top down a bit. The ankle strap is comfortable but could be a bit longer. Overall they are a cute option to the platform Birks that are very uncomfortable imo. Love the options to order half sizes. I’m usually a 6 in Ugg boots but ordered my regular shoe size 6.5 and they fit well. My heel would be at the very end of my sandal if I sized down. True to size. Keeping and will order in another color!

More comfortable than flats!
Size: 8.5, Color: Bay Fog
I love these sandals! They run true to size, and they’re sooo comfortable. I was worried about getting fakes, but these were the real deal. The color is lovely (light purple). The foot bed can get dirty, but I find them to wash up nicely (by hand, not machine). I have purchased two more colors since! So much better than flats!

Comfy dual-mode sandals
Cute, quite comfy to walk in and love the support of the heel strap! It is not as comfy if using in slipper mode because the straps don’t keep your foot tight enough. I am usually a 8.5 but it runs slightly small so I switched up to a 9.
