The Planet Jupiter (astropical)

The Planet Jupiter

Acquisition type: Lucky imaging

Finally a solar system session after a long hiatus. Seeing and sky quality were, astronomically speaking, nebulous, yet the results not that bad, especially Jupiter unveiled clearer than expected with the Powermate. The GRS came around the western limb after midnight in that I stayed up longer to the delight of the mozzies and for better seeing as Jupiter was rising up to 65°. According to my observation the GRS currently is at around 35° in system II. Capture duration was limited to 90 seconds to avoid blurring by Jupiter's fast axial rotation. The Jupiter image is 1.5x drizzled. Saturn was too faint behind haze for reasonable imaging, but I captured it anyway just for decorating the lunar photo. The maximum elevation of the moon in Capricorn was a mere 40° and descending quickly. Favorable libration in latitude brought the lunar north pole into view.

When de-ringing Jupiter in Registax the moons will be washed out in that I overlayed two images, one of which not de-ringed to protect the anyway tiny moons.

Rev B: small version, not drizzled
Rev C: simply compares drizzle factors (drizzle can also fall from the sky).
Rev D: lunar north pole region with planets inserted to image scale

Also interesting, the sensor temperature of the ASI290MM was 42°C while ambient was 27°C, however, the sensor the Uranus-C camera was only 32.6°C suggesting that the passive cooling in the Uranus-C is working.

Though expected, attempts to plate solve the narrow field of the C8 and IMX290 camera failed formidably.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
