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

very suitable for EAA, or allsky / meteor cam, or portable robot telescope

thoughts:

What if binning by 2, ie 5.9 um pixel size, and increase pixel count to 7712 x 4360 = 33.6 Megapixels?

Dynamic range will be 32 times conventional , 25.68 mm diagonal size, sample price ~180 USD

even if the pixel count is increased 1.5x by width and height ( 18.6 Megapixels), it will still be very attractive

note:

SNR1s:

A smaller value indicates better picture quality at low illumination.
SNR1s [lx] is an acronym consisting of "SNR" (Signal-to-Noise Ratio), "1" (represents that the signal level when noise = 1 is 1), and "s" (for Security).

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°...
