Description:Eyepieces for Those Extra Wide Open Celestial Spaces
With their 66 deg. apparent field of view, our Expanse wide-field eyepieces will definitely turn up the Wow! factor in your deep-sky observing experiences! Imagine taking in objects like the Andromeda Galaxy, the Double Cluster, or the star clouds in Sagittarius in one sweep! With an Expanse in your focuser, you can!

Expanse oculars have big eye lenses and great eye relief (13mm to 17mm). Eyeglass wearers can view the entire field without removing their glasses. All eyepiece elements are fully coated, with the outer lens multi-coated for additional light transmission. Each 1.25" aluminum barrel is threaded for filters and internally blackened to eliminate internal scattering. And their fold-down rubber eyeguards enhance contrast by blocking stray light.

With our Expanse eyepieces you get a super wide field of view and superior optical performance. And check out the price. You also get a bargain!

Some coma in faster scopes, but very good contrast. Excellent for the price, they beat out many of my more expensive EP's.

Good eyepiece for planetary nebula like the Dumbell and Ring Nebulae.
Has some problems toward the edge of field which are noticable on the moon. On-axis views are fairly sharp.

Watch out on fast scopes as it has horrible edge correction. I had to return mine but the 6 and 9 are good in this regard.

Very nice eyepiece. Bought it to fill a gap in my collection and for use at star parties. I find I use it just as much as my more expensive eyepieces and it barlows very well with my shorty plus. Very nice views of planets; compares favorably with plossels, but wider field gives a more pleasant view. Would a 15mm panoptic be better? Definitly yes, but it will also be 4 times the cost. A keeper.
