The monocular produces clear and sharp images. The waterproof shell allows for observation in high humidity, such as rain or snow. For more comfortable use, the eyepiece is equipped with a removable soft rubber eyecup.
BaK-4 optical glass used for optics in this monocular is provides a high degree of transparency. Fully multi-coated lenses provide vivid natural color images.
The monocular’s hermetically sealed construction prevents dust and moisture from getting inside the instrument. The shell is filled with nitrogen, so that the optical elements do not fog up even in sudden temperature changes. The monocular also has a mounting jack for a tripod.

ZWO has released a brand-new FF65APO 0.75× full frame reducer with a four-element optical design. It has a reduction factor of 0.75x, which gives the FF65APO f/6.4 astrograph a shortened focal ratio of f/4.8 and a shorter focal length of 312mm. This allows for less total integration time and a wider field of view, bringing more convenience and possibilities for your wide-field deep sky imaging. The back focus distance is the standard 55mm. It also comes with two thread adapters of M54 and M48, and a built-in M48x0.75 2” filter thread, which makes the connection work simple and convenient.
The Antlia Quad Band Anti-Light Pollution Filter is a light suppression filter for color and monochrome cameras. It is able to shoot most deep sky objects like galaxies, reflection nebulae, emission nebula, and star clusters from a Bortle 8 location to Bortle 1 as its spectral transmission passes through visible light region, near-ultraviolet (NUV) and near-infrared (NIR) region.
