Summary: This little monocular is quite big in size. Have a 42mm objective with 8X magnification. Contrast is quite good for this magnification and great FOV as well. Chromatic aberation minimal. Image is sharp & crisp. But it carries quite a heavy price for this small wonder.
Summary: I got this 8x42 as one of two new primary binoculars for birdwatching. For the last few years I've been using a Nikon Premier 8x20 and a Swift Audubon 8.5x44 roof, but I still wanted a pair of mid-priced lenses that are easier and faster to focus than the Swift. This Celestron Noble's focusing knob goes from minimum to infinity in 1.25 turns--and it turned so smoothly right out of the box. Easy to handle and focus with or without gloves.
Pros: Comfortable to hold, Excellent lenses, Smooth focusing
Summary: The Celestron Oceana Monocular is excellent. The small size makes it easy to carry on the trail and the magnification is enough to bring wildlife close enough to identify. A great little product.
