When I first started using the Fujinon Techno-Stabi TS-L 1640 image-stabilized (IS) binoculars, they ruined other binoculars for me, at least any non-image stabilized models. The Techno-Stabi’s high powered IS immediately immobilizes those shaky stars that are common with high magnification binoculars and the difference is night and day. They are expensive but are currently at their best ever price, so I would highly recommend grabbing them while they are discounted.

The Fujinon Techno-Stabi TS-L 1640 image stabilized binoculars sit near the top of the binocular pyramid alongside the other best image stabilized binoculars thanks to their premium Fuji optics, lightweight build and powerful 3-degree image stabilization (IS). It is some of the strongest IS on the market, only being out ranked by other Fujifilm IS binoculars.
40mm objective lenses aren’t the biggest for stargazing, where 50mm is the gold standard for low light, but you can’t complain when observing star clusters at 16x magnification with zero shake. Even if you were using 16×50 binoculars without IS, that extra light-gathering ability would be useless when observing overhead without a tripod, the resulting view likely to be a mess of squiggly lights.
My favorite target with these was the Mirfak cluster in the constellation Perseus, which I could actually identify at this magnification thanks to the IS. It’s amazing using them without the IS, then switching it on and watching the detail of the night sky emerge. They sit in a higher price bracket than regular models, but they really are some of the best optics you can buy for a heavy binocular user and now with over $250 off their asking price on Walmart, it’s a great chance to save money on some exceptional technology. We are going to be seeing a lot of deals on binoculars, telescopes and cameras coming up to Amazon Prime Day. It starts on June 23, so make sure you check our Prime Day hub for all the best offers on skywatching gear and space gifts.

Reviews consensus: I rated the Fujinon Techno-Stabi TS-L 1640 binoculars four and half stars for their smooth image stabilization (IS) and lightweight design. Other reviews remark on the high price but argue that it is justified through the exceptional performance of these binoculars, with the difference made by IS like night and day.

✅ Buy them if: You want stock-still images of the night sky while using handheld binoculars.
❌ Don’t buy them if: You want high definition images of deep-sky objects, whilst they can get you better views of them, a special deep space telescope or smart telescope will get you more detailed views of galaxies, star clusters and nebulas.
