Introduction
HandyDob6 is an ultra-light Dobsonian telescope optimized for portability and ease of assembly. Unlike traditional large and heavy telescopes, it features a lightweight yet strong 3D-printed frame that makes assembly and disassembly effortless. It is designed for anyone—from children to adults, beginners to experts—to enjoy astronomical observation with ease. Equipped with a 150mm (6-inch) primary mirror, it allows observation of the Moon, planets, star clusters, and galaxies. It fits into a 17-inch travel bag and is compact and lightweight enough to be carried onboard an airplane.

How to Attach a Tripod and Use Rubber Bands for Balance
How to Install Push-To Air on the Mirror Box
The HandyDob6 package includes a bottom dovetail bracket that allows you to attach a dovetail base to the mirror box. When you install Push-To Air, you also gain an advantage in balance when using heavier eyepieces, as it adds helpful counterweight to the system.
How to Install the Battery in the Red Dot Finder
⚠️ WARNING: KEEP OUT OF REACH OF CHILDREN
Button/coin batteries are hazardous and can cause severe or fatal injuries in 2 hours or less if swallowed or inserted. Seek immediate medical attention if ingestion or insertion is suspected.
How to Adjust the Mounting Tension for the Finder or Smartphone Holder
If the finder or smartphone holder feels too tight or too loose when mounted, you can adjust it using the two position (tolerance) adjustment bolts shown below. As shown in the image, there are two bolts that secure the mounting position—these bolts control how tight or loose the fit is. Tightening the bolts will make the fit looser, while loosening the bolts will make it tighter.
Recommended Tripod Alternative – Folding Stool
If you use a regular photography tripod instead of an astronomical telescope tripod with the HandyDob6, the small contact area may cause vibrations and instability.
As an alternative to a telescope tripod with a wider contact area, we recommend using the folding stool shown below. You can find it on Amazon or at most large retail stores.
If you remove the four rubber feet on the HandyDob6, you can place it directly on a hexagonal camping-style folding stool.
