THIS EYEPIECE FROM Celestron gives a lower magnification than some of the shorter focal length models oil test. Ail eyepiece that gives 180x to 200x magnification, like this one did wiih our telescope, is very useful because it can be used in average seeing conditions for good views of the Moon and planets.

First up was Saturn. The image was clear and sharp but in average seeing conditions, the low-contrasL of the surface markings made them difficult to detect; other eyepieces in this test made them

much easier to pull out. Problems with contrast continued with Jupiter. The dark orange-red north equatorial belt should have stood out much more, while a number of the belts and zones at higher latitudes were almost invisible.

Venus does not bear high magnifications well and 200x is the usable limit for the planet, but the view of Venus was similarly noL as impressive as others we saw while testing. Views of the Moon were reasonable, however; shadows within the lunar craters came oui rather well.

It was surprising that with this large eyepiece, which proLrudes some way from the telescope, we struggled to split the two components of the double star Epsilon

Bodtis, With the Baader Genuine Ortho and Hyperion eyepieces of the same focal length we were able to resolve the double star a lot better. Given its price, we were expecting better things of this eyepiece.
