Sporting the extremely large light bucket users have come to expect from a Dob, the Explore Scientific 16" f/4.5 Dobsonian Telescopegives users exceptional performance with a low dollar-to-aperture cost. Its oversized parabolic primary mirror is highly reflective and corrects spherical aberration to eliminate distortion across the entire field of view, especially at the edges.

The large 16" aperture draws in a tremendous amount of light to reveal awe-inspiring details of the moon and planets. Deep sky objects will be visible, even for inexperienced observers, and bright star clusters can be resolved to their core. Its f/4.5 focal ratio and 10:1 dual-speed helical focuser make this an ideal choice for imaging. The fast focal ratio enables devices to capture images in less time than slower scopes, while the unique focusing mechanism employed in the helical design gives it the ability to achieve tack-sharp focusing with zero backlash that rack-and-pinion focusers are generally unable to. This 2" focuser will accept larger eyepieces so users can enjoy a truly immersive visual experience and will ensure larger imaging sensors are completely covered.

The rocker box weighs in at 22 pounds and provides a rock-steady observational platform with very-low vibration. This rocker mount features high-altitude bearings with aluminum structures that allow for fine adjustment flows at high magnifications, and dual radial primary mirror fans to quickly adjust the temperature to reduce distortion. Finally, the tension control handle allows users to adjust the settings, enabling them to move the mount easily and smoothly by hand with minimal vibration and maintain its position when released.

Related Questions and Answers

Q: 1. I have a 114 mm telescope I know this would probably be too big do you have a recommendation anything close would be good.

A: 114mm = 4.48819 inches. The closest size rings B&H would carry would be the Tele Vue Mount Ring Set for 4" OTAs BH #TEMTS4Q • MFR #MRS-4011 or the Vixen Optics Tube Rings with 115mm Inner Diameter (Pair) BH #VITRW115 • MFR #ES2665

Q: 2. Hi, I would like to know The dimensions of the tube, the Ota, how long is the tube, please?

A: The OTA is 24.25 inches in length. 4.38 inches in diameter and weighs approximately 5.60 lbs.

Q: 3. Can I change the focuser's position to opposite side of a tube?

A: No, you cannot.

Q: 4. Is this the Generation II scope?

A: It is the second generation.

Q: 5. Can I change the focusor's position to the opposite side?

A: Unfortunately no, the focuser location cannot be changed.

Q: 6. what is its shipping box's packed weight ?

A: Unfortunately the question you're asking cannot be answered with our Q+A feature. Please contact our Sales directly for assistance.Email: Sales@bhphotovideo.com

Q: 7. Can you get a light shroud for the Explore Scientific 16 f/4.5 Truss Tube Dobsonian Telescope?

A: I have one from Explore Scientific, which cost $120. There are others online who make 16 Dobsonian shrouds for slightly less, but I decided to go with the sure fit and hassle-free in-stock order from the scope's manufacturer.

Q: 8. Does the mirror come with a center dot?

A: Yes it does.

Q: 9. Is this generation 2 telescope?

A: Yes it is!

[16" / 406.4 mm] With this excellent 8 dobsonian telescope I can see the color bands of planet jupiter and I can see clearly the rings of planet saturn and I even saw pluto, and I been taking super clear pictures of the clusters of stars with my samsung galaxy and now I feel like I have an observatory in my house, thank you B&H.

[1826mm] The Explore Scientific AR102 is an excellent intermediate scope. The 102mm glass catches a lot of light and provides a great deal of detail with a low Dawes limit. The controls are smooth and solid. Because of its' long focal length, a more substantial mount would be useful to prevent some wobbling during adjustments. I would definitely buy this scope again.

[1826mm] This is my third telescope. I got it mostly for traveling but I find my self using it quite a bit at home too. Its light, easy to put together, easy to use, versatile and of a great quality. Mine worked straight from the box without having to be collimated (even though is recommended for any telescope). Yes, its not going to be as powerful as a 8 or 10 telescope but is more than you need for the solar system (Moon, Jupiter, Saturn etc.) and even deep space observation. Wait, its getting better. It was extremely easy for me to adapt a DSLR camera to it and in the first night I got great pictures with the moon craters. The holding tray on the tripod is extremely useful. The tripod itself is sturdy and good quality. 
Optics are decent. Of course it never hurts to get better quality optics (Explore Scientific have plenty of them in the store) but if you are pleased with the stock ones you dont have too. They will do the job.
I recommend it.

[2"] This is my first scope and am very happy with it. Not a fan of how the base assembles but it is sturdy after I applied glue to the joints. Tool-less mirror collimating is very handy. The red dot finder works well but kind of wish the brightness could go down a bit more. Unless you’re pointing at the moon, you can’t see anything but the dot in the viewfinder. Views are clear and after a little practice, easy to point and get on target. Looking forward to many nights observing with it.
