Antares Speers-Waler Série 3 31,5 mm 94° (SW31.5S3)

I've used this eyepiece on 3 nights so far with my 8" Dobsonian. I love the wide angle views - I even need to move my head around to look to the edges of the view. The only other eyepieces I've used are the Celestron 25mm Plossl that came with my telescope and a pair of 15 and 9mm Antares eyepieces (W70) that I've bought. Compared to those eyepieces this one is in a whole different league. The views are immersive and with my eyes I can't see the black edges of the eyepiece when viewing - just stars out to my peripheral vision. I haven't noticed any visual aberrations or distortion when I've used the eyepiece. I have never had the opportunity to try a Televue or other high-end eyepiece so I can't compare to that - but from my experience (which is limited) this is a great eyepiece.
