Orion 9946 ShortTube 80-T Refractor Tele

Our popular ShortTube 80-T compact refractor is back! This wide-field wonder is outfitted with a correct-image 45-degree diagonal and a correct-image 6x26 finder to provide a correctly oriented image for daytime Terrestrial (hence the "T" in 80-T) observing. Just pop it on your favorite field tripod or tele and it's ready for grab-and-go-anywhere action. Housed in the ShortTube 80-T's 15" aluminum optical tube is an 80mm (3.1") achromatic objective lens that is multi-coated for outstanding light transmission. Its short 400mm focal length (f/5.0) means you'll enjoy a generous field of view as you take in the scene in high definition. The oversized aluminum dew shield guards against moisture accumulation on the lens and blocks off-axis light for better image contrast. The ShortTube 80-T 80mm Refractor Tele comes equipped with a 1.25" cast-aluminum rack-and-pinion focuser, which has a dovetail finder shoe molded into the housing. Another nice feature is that the drawtube collar sports male T2 threads, which allows attachment of a DSLR or mirrorless camera directly to the drawtube via a T-ring (sold separately) for prime focus photography. The two interchangeable Sirius Plossl eyepieces of 25mm and 10mm focal length deliver low 16x and high 40x magnifying power, respectively. Their optics are multi-coated to render bright images and their barrels are threaded to accept optional Orion filters. Preinstalled on the ShortTube 80-T is a dovetail ing bar that allows attachment to any with a Vixen-style saddle or to any photo tripod with a 1/4"-20 threaded post (via one of the tapped holes in the bottom of the dovetail bar). And while the ShortTube 80-T is optimized for terrestrial viewing, why not turn it skyward in the evening for some stargazing? Scan the Milky Way for buried treasures, or focus it on the Moon for some jaw-dropping views of the rugged lunar landscape. Day or night, this is one FUN tele.
