Comet c/2023 A3 Tsuchinshan-ATLAS

 Oct 2024



过近日点后,紫金山-阿特拉斯彗星与太阳的角距离逐渐减小,并不断地靠近地球,10月12日与地球的距离达到最近,其亮度也有望持续增加,届时,彗星将以更宏伟的姿态出现在人们的视野。

随着紫金山-阿特拉斯彗星的移动,它在天空出现的位置也在变化。10月上旬之前,彗星出现在早上的东方低空;但在10月4日至11日,彗星位于太阳附近不易观测;10月12日以后,彗星将出现在日落后的西方低空,角度不断升高,但是亮度迅速下降。

观测彗星时,可在天气晴朗、大气通透的时候,选择位置高而开阔,光污染小的地方,用相机拍摄或用双筒望远镜观测,也可以尝试将手机固定后长曝光拍摄。由于紫金山-阿特拉斯彗星靠近太阳,使用望远镜观测时一定要注意安全。

Starvis-2 IMX585 , and some thoughts

The new product uses Sony’s proprietary “STARVIS™ 2” technology, which delivers high sensitivity and high dynamic range (HDR) using back-illuminated pixel technology specially designed for security cameras, resulting in an 88 dB dynamic range, approximately 8 times that of conventional 1/1.2-type 4K-resolution image sensor*1 in a single exposure. It also increases the sensitivity in the near infrared range by approximately 1.7 times compared to conventional model IMX485 other Starvis-2 products:  2.0 um pixel pitch: IMX675(2.0um, 5.12MP), IMX676(2.0um, 12.63MP), IMX678(2.0um, 8.4MP) 2.9 um pixel pitch:  IMX662(2.9um, 2.4MP),  IMX664(2.9um, 4.16MP), IMX585(2.9um, 8.41MP) - NIR enhanced , 8.41 Megapixels -90 fps  -MIPI CSI2 announce June 2021 , starvis-2 product map   very suitable for EAA, or allsky / meteor cam, or portable robot telescope compare eVscope's FOV IMX585(blue box) with IMX224(yellow box) on Messier M42 thoughts: What if binning by 2, ie 5.9 um pixel size, and increas
