お気楽な星見 小口径でもこんなに見える。 近くで撮ってもこれだけ写る。 がんばらない星見で楽しんでいます。 ASI462MC vs ASI290MC. In general, the ASI462MC and ASI290MC cameras share very similar parameters, but this ASI462MC has a lower readout noise and higher QE value. USB 3.0 Port and ST4 Port. USB 3.0 Port: Provids 5Gb bandwidth to let ASI462 run at 136.1fps (10bit, high-speed mode) or 63.9fps (12bit, normal mode) at full resolution (2.1Mega).There is a protect window before the sensor of ASI290 camera. Our ASI290MM and ASI290MC comes with the D21 AR window, thickness is 1.1 mm. While ASI290MM-COOL and ASI290MC-COOL has the D25 AR window, thickness is 3 mm. 6.5 Analog to Digital Converter (ADC)After dealing with the sampling of the ASI224MC, here is a second article that talks about an essential accessory: the IR-cut filter.. Digital cameras, whether they use CCD or CMOS chips are highly sensitive in the near infrared. This wavelength domain, that the human eye can not see, is very interesting for planetary imaging, but there is one situation where we absolutely don't want it ...
