Messier 78 or M78, also known as NGC 2068, is a reflection nebula in the constellation Orion. It was discovered by Pierre Méchain in 1780 and included by Charles Messier in his catalog of comet-like objects that same year. [4] M78 is the brightest diffuse reflection nebula of a group of nebulae that includes NGC 2064, NGC 2067 and NGC 2071.
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 ...

Nasa’s Orion spacecraft is making its way back to Earth after a trip around the moon that lasted 25 days. The uncrewed capsule, which is designed to carry astronauts, is set to splash down in ...
WISE achieved at least 68, 98, 860, and 5400 μJy; 5 sigma sensitivity at 3.4, 4.6, 12, and 22 μm for the WISE All-Sky data release. [27] This is a factor of 1,000 times better sensitivity than the survey completed in 1983 by the IRAS satellite in the 12 and 23 μm bands, and a factor of 500,000 times better than the 1990s survey by the Cosmic ...
The Optical Monitor (OM) is a 30 cm (12 in) Ritchey–Chrétien optical/ultraviolet telescope designed to provide simultaneous observations alongside the spacecraft's X-ray instruments. The OM is sensitive between 170 and 650 nanometres in a 17 × 17 arcminute square field of view co-aligned with the centre of the X-ray telescope's field of view.
The telescope used by Berkowski was attached to 6 + 1 ⁄ 2-inch (17 cm) Königsberg heliometer and had an aperture of only 2.4 in (6.1 cm), and a focal length of 32 in (81 cm). Commencing immediately after the beginning of totality, Berkowski exposed a daguerreotype plate for 84 seconds in the focus of the telescope, and on developing an image ...
