The W70 series eyepieces offer extra field and extra eye relief without sacrificing image quality. Many observers don't like having their eye too close to the eyepiece. On average, the W70 series oculars have an eye relief of 15mm. Combine that with a wide apparent field of view and you have eyepieces that are very comfortable and nice to use. Larger clusters and nebulosities will now easily fit into your field of view at higher magnification, and your eyeball won't be pressed up against the glass. Standard features include multi-coating, fold-down rubber eyeshield, rubber grips, standard filter threaded barrels and edge-blacked lenses. We also include a free bolt case with each eyepiece you purchase.

It's pretty much the only choice.Pros:
Strong Construction,CompactCons: Comments:
This is pretty much the only choice for reticle eyepieces and for finder scopes. And it is only available here. I did purchase another brand a while back that had a flashing feature but it was big, bulky, and broke after first use.
It would be nice for these things to turn off automatically after a few hours of non use. I just can't seem to remember to turn them off and I'm always replacing batteries.
