Jupiter, 5 November 2020. QHY5III462C camera test.

I tested the new camera QHY5III462C for Jupiter. The Sony imx462 sensor is distinguished by its high sensitivity to infrared rays, which allows it to be used in monochrome when shooting at a wavelength of 850 nm or more. This camera is especially interesting for shooting with a methane CH4 filter (890 nm), since its sensitivity in the infrared range exceeds that of all modern amateur astronomical cameras, including those on Sony imx224, imx290 and imx178 sensors. If earlier when shooting with a monochrome camera QHY5III178m and a CH4 filter I had to set the maximum gain and shutter speeds of 100-200 ms, then with the QHY5III462C camera I can use shutter speeds of 20-30 ms with a gain of about 80%, which greatly simplifies focusing and improves image detail in the expense of a shorter exposure.

I didn’t like the 850nm QHY filter that came with the camera as it transmits infrared radiation at wavelengths less than 850nm. For shooting at this wavelength, I used a ZWO 850 nm filter.

The source ser-videos are available here.
