Giove e doppio transito di Io e Ganymede.

Hi all,

finalmente sono riuscito a completare il mio ultimo lavoro. Mi ci sono voluti sabato, domenica e qualche notte di processing ma credo ne sia valsa la pena. Del resto non capita tutti i giorni di ammirare in diretta Giove con la GRS al centro mentre transitano contemporaneamente le sue lune Io e Ganimede che proiettano le loro ombre sul globo durante il tragitto. Infine la luna Europa, che fino a quel momento era invisibile essendo eclissata dal cono d’ombra di Giove, spunta dal nulla come d’incanto a completare il bel quadretto. Attenzione anche ai particolari su Io che forse evidenziano la presenza di una delle frequenti eruzioni vulcaniche.

Le riprese sono state effettuate la sera del 16 marzo 2016 con telescopio Meade LX200 16” ACF e camere planetarie Magzero Plamx e ASI174MM. Quest’ultima camera planetaria di fondamentale importanza nelle riprese finali grazie al grosso sensore che ha permesso di inquadrare tutti i soggetti contemporaneamente.

Questa è una GIF, ovviamente la versione HD è di qualità nettamente superiore ma comunque rende bene l'idea.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

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.
