There are two things we recommend looking for when eyeing up your next pair of the best binoculars for stargazing: large magnification to bring the cosmos closer and wide objective lenses to drink all that distant starlight in. Can things get better for astronomy binoculars? yes, they can; the Canon 18×50 IS UD proves that adding image stabilization to the two aforementioned prerequisites takes things to a whole new level.

Part of the trouble with high magnification (12x and up) binoculars is that it’s hard to keep them steady when handholding. Most of the time, you have to fix them to a tripod through an adapter in order to keep them steady enough to observe your favorite constellations or favorite wildlife subjects. But, with the inclusion of image stabilization in the 18×50 IS UD

Field of view (60.3-degrees, apparent) was plentiful and it almost felt like stepping inside the binoculars and looking out, rather of the occluded feeling binos sometimes give us when observing. they felt ‘just right’ and did not seem to drop any brightness thanks to superior light transmission, owed in-part to the Super Spectra coating.
