Sky Rover XWA 100° to 110° eyepieces

Introducing the Sky Rover premium line of mega wide eyepieces - the XWA line


An outstanding line of eyepieces offering 100° to 110° apparent field of view providing outstand performance regardless of the telescope you are using (for example f/4).



The new, extreme wideangle eyepieces by Sky Rover with gigantic 100° to 110° apparent field of view.  With their multicoated lenses they offer excellent brilliant and contrasty unforgetable views. These eyepieces offer many modifications to other 100° eyepieces.


We have tested all of the eyepieces in the XWA line in 8 different telescope designs and different focal ratios - we are truely amazed at the quality of image, contrast and ease of use across all the telescopes used.  Using a coma corrector suited to the f/ratio of your Newtonian provides an edge to edge pin-sharp field of view.  NO astigmatism.


The XWA line features:

  • incredibly wide field of view 100° to 110°
  • fully multicoated lenses provide superior light transmittance
  • textured wide rubber grip for easy handling
  • lowered chromatic aberation
  • superior contrast
  • lens edges and internal spacers are fully blackened
  • flaring and ghosting on high contrast objects has been eliminated
  • easily converted from 1.25" to 2" and back by simply removing the included sleeve
  • fully anodized black barrel with high resistance to scratching
  • sealed against water
  • threaded for 1.25" and 2" filters
  • upper eyepiece part conical for best use at binoviewers
  • removeable eyeguard, under this M44.5 x 0.75 OD Thread for Cameras

The XWA 20mm is not currently avialable due to inavialability of some rare earth metals required to make some of the unique glass types that this focal length needs.  As soon as the 20mm is avialable it will be offered here in Astro Shop.
