Sky-Watcher ImagesThe Sky-Watcher SW 90AR-AZ3 offers sufficient resolution for enhanced study of surface phenomenon in the solar-system, and additional structural detail in the brighter, more prominent deep-space objects. This telescope will also serve as a high resolution terrestrial telescope for razor sharp views of distant landmarks, nature and people. As seen through the 90AR, the pock-marked face of the Moon presents a treasure trove of extraterrestrial geographic landscape features. The SW 90AR will deliver breathtaking detail of famous-name high-walled craters and vast flat expanses known as lunar maria (seas). The planet Saturn reveals amazing views of it's ring structure and 4-prominent moons. Jupiter's equatorial bands show good detail revealing numerous discontinuities between the bands not visible in smaller aperture telescopes. In deep-space prominent nebulae and globular star clusters take on greater presence revealing themselves as more than just luminous, ghostly apparitions. Discrete stellar pinpoints manifest themselves to a far greater extent. A number of additional double stars are suitable for study as are satellite transits silhouetted against the surface of gas giants like Jupiter.

AZ3 Altazimuth mount has robust construction and mechanical quality!

Sky-Watcher GreatStart 90mm RefractorThe 90AR-AZ3 is an altazimuth mount telescope. The telescope's mount moves intuitively in vertical and horizontal directions. Astronomical objects are tracked across the sky by actuating the supplied dual slow-motion controls simultaneously in both axes to keep an object centered. The slow-motion controls allow very fine incremental tracking adjustments that precisely facilitate keeping fast moving sky objects centered in the eyepiece. Just a fraction of a turn of the cable control knob is all that is required to keep an object easily captured in the telescopic field of view.

Sky-Watcher GreatStart 90mm RefractorStability of the mount and tripod is critical to the utility and enjoyment of a telescope. Insufficiently rigid mounts and vibration prone tripods act like tuning forks transferring undesirable vibration to the eyepiece. This will deprive the viewer of a steady view. Fortunately, Sky-Watcher mounts and tripods are some of the most stable and robust in their class. The mount of this telescope is made of metal in all critical structural and functional areas. The mount body itself is metal, the gear assembly is metal, the slow-motion cables are flex-steel, the heavy-duty tripod is aluminum, optical tube rings are metal. This telescope is structurally sound and offers smooth, precise mechanical controls.

Sky-Watcher Fall Rebate Sale Note: The SkyWatcher Fall Rebate Sale was set up by the manufacturer to include two kinds of rebates...the instant kind, and the more common mail-in rebate. Normally, the instant rebate is deducted by the seller from the sales price, but the mail-in rebate must be sent in by the customer after the purchase has been made.

OPT wanted to make this purchase a bit easier on our customers. We've already deducted the value of the instant and mail-in rebates from the purchase price! In other words, if a telescope had an instant rebate of $25 and a mail-in rebate of $25, we deducted $50 from the regular price of the telescope....and that is what we are selling it to you for. You're welcome :>) Enjoy your Sky-Watcher telescope!
