... And it also refers to the mount, not only as being an equatorial, which it is, but as "Sagittal". ... The minum tube length is 700mm, but you could reduce that to 620mm by temporarily removing the focussing mount, so it would be quite easy to transport for anyone thinking of travelling abroad for the Transit of Venus in June. ... That separation is just a bit more than the field of view of average binoculars, so you'll have to sweep just a bit below right from Venus. ... Clear skies, Terry Moseley ....

... The highly obscured cases in our sample are generally the bright, central regions of galaxies with high overall attenuation but are not otherwise remarkable. ... The small fraction of highly obscured regions seen in this sample of normal, star-forming galaxies suggests that on 500 pc scales the timescale for significant dispersal or breakup of nearby, optically thick dust clouds is short relative to the lifetime of a typical star-forming region. ...

Curtains of collapsing hydrogen are shown above in green, highlighted by a special filter that isolates light from this specific atom. ... Many of the stars appear red because of the high amount of dust in the Lagoon Nebula . Red light penetrates dust clouds best, although enough dust will block all visible light and leave a dark nebula . ...

...

... It is extremely high surface brightness owing to star formation which is pervasive throughout the entire disk. Some very large H II regions can be found at large radii from its center, and this is somewhat unusual. The large number of massive stars now forming in M101 has made it an excellent case for study in the Ultraviolet, where faint extensions beyond the optical limit of the galaxy can be seen. ... This exposure was taken in the blue, again with reimaging optics on a 52-inch telescope. ...

However others are less pessimistic and it has even been claimed that the mysterious ?Wow! signal? received in 1977 originated from the direction M55.б  Sadly, this still unexplained pulse of radio energy originated from a location rather to the northwest of M55 so I doubt if the source was this cluster (if indeed the signal was genuinely of extraterrestrial origin). ...

... The formation of multiple images of a distant quasar by the gravitational lensing effect of a foreground galaxy may be very simply, and faithfully, accounted for by a wine glass experiment. Figure 1. In the wine glass experiment, a bright compact light source (at the top of the photo) serves as a distant quasar. The wine glass on the table distorts the light rays from the "quasar" and produces a caustic having with a triangular shape (see enlargement in Figure 3 ). ...

... The Galactic low-mass X-ray binary GS 2023+338 was discovered during the burst on May 22, 1989 with the Japanise satellite Ginga (aka Galaxy). The flux reached 17 crabs (this unit of flux measurement is an bright X-ray source, Crab Nebula) at 10-35 keV. ... No other radio telescope worldwide carried out multi-frequency measurements. ... Upon 14 days the radio flux fell below the detection level at the RATAN-600 in relation to the decrease of the X-ray flux. ...

Halo around the Moon. Halo arises when the light beams refracted on the high clouds icy chips ina form of a six side prism. As a result we see a small halo circle with a 22°-radius. The big circle is formed by the beams paased through the side edge and the base of prismochips. Its radius is equal to 46° (nearly). The big circle is observed rarely and is shining weaker but it is easier to observe it near the Sun, if comparing with the small halo invisible in the bright Sun light. ...
