In the application of the proposed single-user naked-eye
3D display based on time-spatial multiplexing technology, the viewer may move around during viewing process, and the movement might be large or small.
The solution also supports 120Hz and 9 view image output, suitable for various naked-eye
3D technologies including lenticular, barrier-type and direct-lit backlight.
First of all, Sirius is only 8.6 light-years away--making it the closest naked-eye
star that's ever visible from most of North America and Europe.
No one constellation has 1,000 naked-eye
stars in it, but if you take the stars brighter than 6.5 in the Orion group--Orion (204), Taurus (223), Auriga (152), Gemini (119), Canis Minor (47), and Canis Major (147)--and add them together, you get 892.
At that time, the comet resided near the orbit of Jupiter and its brightness suggested that it would rank as a naked-eye
spectacle when it made its closest approach to Earth late last month.
But there's no replacement for the wide and natural naked-eye
The vinegar-swab and naked-eye
inspection by a nurse "provides great coverage in not as many steps" as the other techniques, she concludes.
Sometimes even altitude can have an impact on how effective naked-eye
sighting of the moon can be."
One pastime I've come to enjoy is naked-eye
Back in my March column I discussed seeing Venus and Sirius naked-eye
when the Sun was still above the horizon.
The latter idea is particularly appealing every eight years when April begins with one of my favorite recurring celestial events: the close meeting of Venus, the loveliest naked-eye
planet, with the Pleiades or Seven Sisters, the loveliest naked-eye
star cluster (see page 48).
observer will marvel at the constellation canopy that floats above Orion and Sirius.
