Review Summary

No eyepieces came. I did not realize the range of their expense. Some of them contain 6 or 7 lenses and weigh as much as a pound or more. Some in an economy price range perform better than 90% as well as the best. There is a universe of eyepieces. You would be surprised at how well some of the least expensive ones compare to the higher priced. A Barlow lens will double the power of each eyepiece. In mine the lens element may be unscrewed from the Barlow lens housing and screwed into the eyepieces thus increasing the power maybe 25 or30 per cent giving you some varied and pleasing magnifications. A variable adjustment filter is a must for viewing the moon. The moon will nearly blind you using this scope. I collimate the scope without a collimation laser or tool. I position the telescope vertically and remove the eyepiece. This allows me to see the primary mirror through the secondary mirror. I hold my eye very near the hole and center the primary mirror in the secondary using the 3 adjustments. Next, I adjust the primary mirror using the wrench that came with the scope. I adjust until the reflection of my eye is centered in the small circular marker on the primary mirror. I slowly back away from the eyepiece viewing hole to a distance of about 6 or 7 feet. If the reflection of my eye and the primary center mark is perfectly centered, I know that the mirrors are in perfect alignment. Seeing stars as perfect points with uniform fading crosshair rays is good collimation. I notice that the scope is holding alignment better each time I move to my viewing location even with the minor bumps and agitations while rolling my homemade platform. I have a black rubber car mat with tiny black knobs that cushion against shock and prevent the scope from sliding while rolling across the lawn. One night the laser dot finder scope snagged on my back door as I was pulling the scope out into the yard. The rocker box pulled out of the primary mirror box toppling the scope to the ground. The only damage was the plastic piece that connects the finder scope to the circular bracket housing the secondary mirror. I located a piece of 1/4 inch thick high quality veneer wood and cut a piece 2 and 1/2 inches long with a 2 inch base to mount in the telescope bracket and a 1 inch top with a center notch that mounted perfectly into the finder scope. I painted this little piece of wood flat black and it functions as well or better than the original part. For kicks and a back up, I ordered another similar red dot laser finder scope from China for about $10. Hey, a country boy can survive and often even proudly rise. I can do a lot of minor, sometimes major fixes and have found that often a roll of duct tape (preferably high quality, professional) can get you through some usually temporary, sometimes permanent quick and essential fixes.

Become an astrophotography enthusiast's dream with the 16" 4.6mm f/4.5 Truss Tube Dobsonian Telescope from Explore Scientific, a game-changer in the world of amateur astronomy. This sophisticated instrument revolutionizes your stargazing experience, offering a sturdy and durable design that's both high-quality and advanced.
The Dobsonian telescope, pioneered by John Dobson, has dramatically altered the landscape of amateur astronomy. Before its inception, enthusiasts were limited to smaller telescopes with basic mechanics, struggling to glimpse the finer details of our solar system's marvels. Now, with the introduction of this 16-inch aperture Dobsonian, you can delve into the cosmos like never before, capturing breathtaking views that were once only accessible to those with professional-grade equipment.
This telescope's large 16-inch aperture is its crown jewel, allowing an impressive amount of light to flood the optical tube, illuminating celestial objects in stunning clarity, even under low-light conditions. Whether you're observing the delicate polar caps of Mars, the majestic rings of Saturn, or the intricate structures of distant galaxies, this telescope provides an unparalleled window into the universe.
The truss tube design of this Dobsonian not only contributes to its sophisticated appearance but also ensures that the telescope remains lightweight and portable. Its structure has been meticulously optimized for maximum rigidity with minimal weight, making it an ideal choice for astronomers who value both stability and portability. The high altitude bearings, paired with optimized aluminum structures, allow for smooth and precise adjustments, even at high magnifications, making it the perfect tool for deep sky observation.
With a 406mm mirror, this telescope collects over 2,400 times as much light as the human eye, revealing details on planets and deep sky objects that will astonish even novice observers. Star clusters are resolved down to their cores, and the lunar terminator's shadowy delineation becomes an experience you'll never forget.
Equipped with a 2" focuser that features helical gearing and a 10:1 reduction, this telescope ensures sharp, fine-tuned images. The included LED Red Dot Finder, collimation assist tool, soft light baffle, and two radial main mirror fans expedite temperature equilibrium, enhancing your viewing experience. Additionally, the telescope is ready to accommodate Explore Scientific's optional coma corrector, further refining your observations.
The 16" 4.6mm f/4.5 Truss Tube Dobsonian Telescope by Explore Scientific, available at Adorama, is not just an instrument but a portal to the cosmos, inviting both seasoned and budding astronomers to explore the night sky with clarity, ease, and precision.
