Supernova SN1572

又名「第谷超新星」,「仙后座B」，「閣道客星」

當時明朝皇帝明穆宗朱載坖剛過世，十歲的小皇帝登基才兩個月，這個天文異象對小皇帝造成不小的心理陰影：

明神宗實錄六: 十月初三丙辰夜，客星見東北方，如彈凡出閣道旁。壁宿度漸微芒有光，歷十九日。壬申夜，其星赤黃色大如盞，光芒四出，占曰:是為孛星，日未入時，見占曰:亦為晝見。是時，上於宮中，見之儆懼，夜露禱於丹陛。輔臣張居正等言:君臣一體，請行內外諸司，痛加修省，仍請奏兩宮聖母，宮闈之內，同加修省從之。諭禮部曰:玄象示異，朕心深切警惕，內外諸司宜痛加修省，便查舊例來行。禮部奏請如嘉靖四十二年火星迭行之例，百官青衣角帶辦事五日報曰:你每為臣的都要體朕敬畏天戒之意，著實盡心修舉職業，共圖消弭，毋徒為修省虛文。按是星歷萬曆元年二月，光始漸微，至二年四月乃沒。

CMOS sensor trends and astrophotography, from amateur astronomers perspective

Nowadays, even in low light conditions, digital camera can quality pictures with higher ISO, noise and hot pixels have been gradually reduced. Sony has introduced back illumination process for consumer market. Sony BSI sensors evolved from Exmor to now Exmor RS( stacked) technology. This stacked technology allows further chip size reduction, which has strong demands in smartphone camera market. Digital astrophotography is also benefited from such advances, utilising Back Side Illumination technology Exmor: Within the CMOS sensor, it outputs low-noise digital signals by "on-chip column AD conversion" and "dual noise reduction" to suppress noise in the first half of the process In low light conditions, when a wide aperture is desirable to collect as much light as possible. At apertures wider than f/2.0, back-illuminated Exmor R sensors are significantly more efficient at collecting light than conventional, front-illuminated sensor...

ultrafast rendezvous to ISS

14 Oct 2020, being the first to use a new “ultrafast” rendezvous” scheme with the ISS. Following a flawless ascent to the correct orbit, Soyuz 2 .1a , Soyuz MS-17 caught up with the orbiting laboratory in only two orbits (three hours), halving the time it takes for crew to get to the Station. The three space travelers of the Soyuz MS-17 mission launched on a six-month mission the International Space Station. previous 3/4 orbit rendezvous: Soyuz MS-16 4 orbit rendezvous A three-orbit profile was deemed possible without major flight design changes after inauguration of the Soyuz 2-1A rocket that provides a much higher orbit injection accuracy than its predecessors and would allow the two correction maneuvers on Orbit #2 to be eliminated while the Automated Rendezvous Phase would still remain untouched. The deletion of the Orbit #2 maneuvers was expected to slightly tighten the already restrictive phase angle window from and upper limit of 30-35° to 25-28°...
