player one Saturn SQR camera

 This Player one cam has much higher full well and FPS than Zwo ASI version: this is even faster than read mode 0F at full resolution was it due to over-clocking as in personal computers?  Speculation: by slightly over-voltaging the CMOS chip, so that the chip can run in slightly higher clock rate. But data is still output within the required spec. Of course the the extra heat needs to be properly dissipated, eg active cooling using IMX323 for illustration below: the analog voltages, VDDH 1000 FPS kickstarter   PAM4  demodulation  Multi slope ADC       MTK imagiq  APU Paddle lite AliExpress   Poseidon pro  IMX571

saturn jupiter conjunction Dec 2020

木星与土星会合周期差不多为20年,此次“合”是自1623年7月17日以来最接近的一次,在“合”时两者仅0.10421度。下一次木星合土星发生在2040年11月5日,不过间隔将比这次更宽,约1.2度。若要看到同样接近0.1度的“合”就要等到2080年3月15日了,所以今年这次机会很难得!  this is from Dr. Sebastian Voltmer, taken in 2007 using a C11 for 21 dec 2020: it will be as close as 0.06 arc min 21 Dec 19:00 (UTC+8), looking west: skyatnight space   reference: what is conjunction,甚麼是相合: 赤道坐標  視赤經相同 ,或視地心經度(apparent geocentric longitude) 有趣天文現象
