Tele Vue Ethos Overview

With its exceptional 100° apparent angle of view, the Tele Vue Ethos 6mm Ultra Wide-Angle Eyepiece offers a comfortable eye-relief despite the short focal length, with high contrast and excellent on-axis sharpness; and virtually zero astigmatism or field curvature across its expansive 100° field of view. Combining a hyper-wide apparent angle of view with its shorter focal length, this Ethos delivers high magnification for enhanced detail on near and deep-sky objects alike, while still offering an expansive and immersive observational experience.

A unique design characteristic of the Ethos allows it to be used with smaller, more common-sized, 1.25" drawtubes and accessories; and  larger 2" versions. This provides users with an easy and convenient way to expand its functionality and versatility, without limiting its use or relying on eyepiece holder reducer adapters.

When used in the 1.25" mode, this model is parfocal with a variety of Tele Vue eyepieces, requiring little or no refocusing when changing between them — greatly decreasing vibration and increasing convenience. A textured collar around the housing provides sure handling in cold weather or while wearing gloves, and a fold-down rubber eyecup allows for comfortable use with or without eyeglasses.

B&H is a great company. When I ordered this TeleVue 6mm Ethos, it was shipped the same day! This eyepiece is high-quality and produces the most incredible views for many people in my audiences.

Using in 10 Dob...

I've had this eyepiece for a couple of weeks so here's my experience with it: I'm using this 6mm Ethos in an Orion XT10 plus. To reach focus I either use the 2 tube extension that came with the scope or I stick it in the 1.25 adapter. The adapter that came with the xt10 puts little thumb-screw marks in the side of the eyepiece when you tighten it so I bought the Tele-vue 2-1.25 flat top adapter which has a brass ring inside it. That reaches focus just fine as well. I live near downtown San Diego (lots of light pollution) but this eyepiece STILL can resolve tons of stars in the M13 (Hercules) cluster. Empty areas of space look very nice and dark and it pulls more faint stars into view. Even better then my Baader Hyperion Zoom. The detail that I can now see on the moon when I use this in combination with a baader .6 ND filter stacked with the Baader Moon and Skyglow filter is absolutely stunning. I'm very happy with this eyepiece. The Stardust lens case/tube in size D fits it nicely and keeps it safe. Can't wait to take the scope up to Mount Laguna which is my local Dark Site. Buy one. If you have a dob like mine then it will be near the furthest limit of your focuser but it will reach focus with either the 2 extension or the 1.25 adapter.
