Solid Construction and Quality Components
The Apertura AD8 8" Dobsonian telescope features solid construction and quality components. Its 8" parabolic mirror is made from quality materials and figured to 1/12th wave. This mirror is finished with an aluminum and silicon dioxide coating that delivers 93% reflectivity to ensure the brightest possible images. The primary mirror sits at the end of the optical tube in an adjustable mirror cell. If the telescope were to ever become misaligned, this mirror cell can be adjusted with hand-knobs in conjunction with the included laser collimator to ensure perfect alignment--no tools required! The optical tube assembly is made from steel for durability and beauty and is fitted with a 2" dual-speed, 10:1 Crayford-style focuser for smooth, easy focusing.
Dobsonian Rocker Box for Smooth and Easy Navigation
What differentiates a Dobsonian telescope from other Newtonians is the ingenious base, or rocker box. The tube of the AD8 sits onto the base and can then be easily moved up, down, or to either side. For balance in the desired position, tension can be adjusted using the large aluminum knobs on either side of the telescope to tighten or loosen. The bottom of the base is a "Lazy Susan" style, allowing for smooth, 360º horizontal rotation. Sealed ball bearings also allow smooth altitude adjustment. This base also comes with a 4-slot eyepiece tray to hold accessories.
Performance and Simplicity Perfect for the Beginner
Dobsonian telescopes are known for their simplicity and affordability--a reputation the AD8 meets and exceeds! A solid, 8" aperture is married to a simple and versatile Dobsonian base. With no need to worry about expensive and complicated electronics or external power sources, this telescope is a great first telescope to get acquainted with the night sky. Also including everything needed to start exploring the sky right out of the box, the AD8 by Apertura is a great combination of value, performance, and simplicity!
Tons of Accessories Included
The Apertura AD8 Dobsonian telescope comes equipped with many great accessories to make observing the night sky fun and exciting right out of the box! A primary mirror cooling fan helps your telescope reach ambient temperature quickly and efficiently. A 1.25" adapter allows you to use either 1.25" or 2" eyepieces and filters. 9 mm Super Plossl 1.25" and 30 mm Super View 2" eyepieces provide a variety of views of celestial objects. A 35 mm extension tube helps bring images into focus when used with different eyepieces or camera setups. A 1.25" moon filter provides higher contrast views of the moon by eliminating bright surface glare. The 8x50 right-angle image finder with bracket allows for quick and easy spotting of an object for observation. The laser collimator allows for collimation of the mirrors if ever they were to become out of alignment. Lastly, the 4-slot eyepiece tray mounted to the base allows for safe keeping and easy access of eyepieces while out in the field.

How to Set Up and Use the AD8 Dobsonian
Please Note: A physical copy of the instruction manual is NOT included with this Dobsonian, however you are welcome to download a PDF of the Apertura AD Dobsonian Manual any time you like. Thanks.
A Dobsonian is perfect for beginners as well as advanced amateur astronomers. Unlike computerized telescopes, a classic Dobsonian does not find objects for you. You do that yourself. It may be a challenge at times, but you will have the honor of learning the night sky. To set the Apertura Dobsonian up for a night of viewing, just put the rocker box on fairly level ground, set the optical tube in the cradle, slide the finder scope on, put an eyepiece in the focuser, and start observing. There are no motors or electronics to deal with, and you won't hear anything except the hum of the fan during cool down. To move the telescope, push or rotate it in the direction you wish to go, and use the 8X50 finderscope to help you center the object in your field of view.
This telescope has a unique design that allows for easier balancing of the telescope in altitude. A two piece CNC machined aluminum side-bearing holds the weight of the telescope OTA, and when you need to make tension adjustments--say because you added a heavier eyepiece or other accessory--all you need to do is turn the knurled knob (there’s one on each side of the rocker box). With a little bit of experimentation, you’ll find the perfect balance for your Apertura AD8 Dobsonian!
We recommend a planisphere for your latitude to help you get your bearings and find brighter objects, as well as a more extensive star chart of some kind to help you locate fainter objects. There are several inexpensive (or free) programs and/or websites available that allow you to print out a nightly star chart for your location and observing date and time.
