Regal M2 16-48x65 ED is a compact and lightweight tube built in a magnesium housing with full-coverage rubber reinforcement of solid quality.
On the front of the extendable lens hood there are sighting slots to facilitate target finding against a contrastless sky, for example. The tube foot is tiltable with fixed click stop positions. The entire house is filled with nitrogen gas and thus completely sealed against water and dust. The shape is quite slim and the focusing knob is recessed on the right side of the prism housing, which provides good ergonomics with the left hand resting over the prism housing when viewing. The focusing is also double with a high-geared fast focusing and a low-geared fine adjustment. With fluorite-containing ED (Extra low Dispersion) glass in the lens, chromatic aberration (color bleeding) is minimized for maximum contrast, resolution and accurate color reproduction. The tube comes with a zoom eyepiece that provides 16-48x magnification with a good field of view. The eyecup is of the screw type. Since Celestron are specialists in astronomical optics, they have chosen to provide the eyepiece with a 1.25'' astromount, which gives great opportunities to equip the tube with a variety of such eyepieces on the market. The eyepiece is also directly prepared for digiscoping. The eyecup is unscrewed, exposing a T-adapter where the T2-adapter fits directly. Delivered with a green emergency bag in cordura, lens and eyepiece protection in aluminium.
