This image of Jupiter was captured on the morning of September 29 (local time) from my home terrace in Singapore during a session characterized by unstable seeing (but quite good during this light collection), and poor transparency that significantly impacted the collected signal. The continuous passage of clouds also created additional challenges.
This is the first test I run on the new P1 Mars-M-II camera (based on the Sony IMX462 mono sensor), which is characterized by an exceptional sensitivity in the infrared and deep infrared and very low readout noise.
I used on this Jupiter image a CH4 (methane) filter and a APM 2.7x Barlow to optimize my f/3.8 native Newtonian working at an optimized sampling for IR and deep IR (like CH4) wavelengths, avoiding to waste the light collected.
Despite the poor transparency of the evening, the camera performed very well and truly surprised me. I could work with a very short exposure time (5 ms), much less than I expected, and consequently achieving high fps with the image still looking very decent and quite noise free. By far the best result I saw among the cameras I tested.
The attached image is the result of derotating 5 sequences of 90" each at 200fpi, of which I selected 70% of frames to stack. I pushed admittedly a bit more than I usually do on the processing, especially considering I merely collected 7.5 minutes of data, but I wanted to shows the many details on the surface usually not so easy to resolve at this wavelength. The dark spot on the bottom left is Ganymede's shadow that was just beginning transit over the disk of Jupiter at that time of imaging.
Excellent test result, I am positively impressed
