TS Eyepiece specifications

Nice low cost looking little eyepiece these  http://www.365astronomy.com/TS-Ultra-Wide-Angle-Eyepiece-20mm-1.25-66o-with-Improved-Coating.html 

However can't find anything ref the eye relief of these. I used to have a 12mm ep that was very similar from TS but I am interested in the 20mm version for my travel scope so just wondered if anyone has/has had one and any comments they have regarding the ER.

TIA

I've owned a few of those. Their specs are the same as the Skywatcher UWA 66 degree and the Orion (USA) Expanse ranges apart from the additional coatings. The eye relief I have for them is as follows:

6mm = 15mm

9mm = 15mm

15mm = 13mm

20mm = 17mm

Nice eyepieces for the price - the 9mm is probably the best one.

PS: The Skywatcher branded ones can sometimes be found cheaper than the 365astronomy price on e.bay.

Good price indeed, but I would pay a bit more and get a 20mm or 24mm MV 68 deg. These are REALLY good value for money, and I at least could use the 20mm (15.6mm eye relief, just enough for me). With 68 deg AFOV and better performance in fast scopes I can live with the slight increase in weight. Just my tuppence

I need a light EP Michael due to the scope intended for. Even the 9mm x-cel is pushing it but this weighs slightly less so should be ok. The maxivision wouldn't cut it i am afraid.

I have the 9mm Agena EWA and its indeed very good for the price even at f/6. The 6mm and 9mm share the design, 6 elements in 4 groups, and both collected tons of positive reviews. Although, the 15mm and 20mm have a different design, 5/3 (missing the Smythe?) and according to multiple reviews are pretty awful off-axis in faster scopes, so be careful.
