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.
