Also known as Sirius, the Inokhodets-RU is an upgraded variant of the Orion with a bigger and different design, the key difference being twin engines. Sirius is a medium-altitude long-endurance (MALE) attack UAV, with a wingspan of 30m, length of 9m and height of 3.3m, a maximum combat load of 450kg, cruise speed of 295km/h, maximum altitude 12 ...
Orion ED120 apo refractor on Orion's Sirius EQ-G "GoTo" and GPS equipped German equatorial mount with portable 12 volt power supply. Orion sold a range of telescopes that they characterize as "beginner", "intermediate" or "advanced", including Newtonians, Maksutovs, Schmidt-Cassegrains, Ritchey-Chrétiens and refractors with or without (sold as optical tube assemblies or "OTA") a variety of ...
Optical telescopes can be classified by three primary optical designs (refractor, reflector, or catadioptric), by sub-designs of these types, by how they are constructed, or by the task they perform. They all have their different advantages and disadvantages and they are used in different areas of professional and amateur astronomy.
Orion just made its final pass around the moon on its way to Earth, and NASA has released some of the spacecraft's best photos so far. Taken by a high-resolution camera (actually a heavily ...
The new space observatory sees pairs of Jupiter-sized objects floating free between the stars.
Comparison of nominal sizes of apertures of the above extremely large telescopes and some notable optical telescopes. An extremely large telescope (ELT) is an astronomical observatory featuring an optical telescope with an aperture for its primary mirror from 20 metres up to 100 metres across, [1] [2] when discussing reflecting telescopes of optical wavelengths including ultraviolet (UV ...
JWST NIRCam observed the central part of the Orion Nebula, including proplyd 114–426. This observation found a dip at 3 μm, which is seen as evidence of water ice . The grain size was estimated to be smaller than 0.25 to 5 μm and the dust+ice mass of the disk was estimated to be 0.46 M E in the silhouette region. [ 3 ]
Former Maryland Gov. Larry Hogan posted eerie video footage on his X account Friday of “large drones” circling above his house just 25 miles from Washington, DC, echoing concerns from ...
