Sky-Watcher 8-24mm Zoom Eyepiece 20149

It allows you to find an object at low power, then zoom in until you reach the desired magnification. The fold-down rubber eyecup provide comfortable viewing for eyeglass wearers.  Apparent Field of View is 40 – 60 degrees.

“The multi-coatings worked particularly well during our field of view tests…one of only two of the zooms on test that didn’t have any internal reflections on bright objects…Rotating the barrel to change magnification is quite smooth… At the 24mm setting the field of view was sharp across 80 per cent of the view…Cranking up the magnification to 8mm, we split the double star Albireo well…Jupiter had good detail as did the Moon at all magnifications…This eyepiece did a great job on a wide range of subjects”
