Jupiter 2021/10/17
Here another three images of Jupiter of that night. This was my second and probably my last session that season.
The seeing was not quite as good and more variable compared to my first session on the 25/09. During the middle image series my green channel was excellent. It therefore shows the most details.
Imaged as usual through a 10 inch Meade ACF with Baader Hyperion Barlow lens in x2.25 configuration, which gives me an effective focal length of about 6.3 m. Camera was an old ZWO ASI 120MM with ZWO RGB filters. All RGB videos were 120 s long each, exposure per frame was between 11 ms and 15 ms; gain 75%; gamma 50.
40% to 45% of the frames were stacked and pre-sharpened in Autostakkert. Then derotated with WinJupos. Afterwards, I combined the RGB images in PS and further sharpened with unsharpen mask. In the end some noise reduction filter.
