The Acuter NatureClose Waterproof is perfect for serious terrestrial observations. Optical performance is excellent, with all models delivering crisp, bright, sharp, high-resolution images, across the entire field of view. An 8-24mm zoom eyepiece is included with each model as standard. The standard multi-coated zoom eyepiece and fixed magnification accessory eyepieces all offer generous eye-relief, and fold-back rubber eyecups, making them suitable for users with glasses. The objective lenses are multi-coated for maximum light transmission and image contrast. Focusing is ultra-smooth and the telescope tube is covered with a protective rubberized paint finish to help protect from the elements. A T2 camera adaptor is available for the attachment of either SLR or DSLR cameras, and can now be used in conjunction with the zoom eyepiece supplied.
