NETTUNO con SMARTPHONE e stacking di filmato

Filmare Nettuno con il telefono cellulare non è impossibile (anche se molto poco agevole) una volta che si è riusciti ad inquadrarlo. La mia personale difficoltà è stata causata dal pavimento in legno (un terrazzo) su cui era installato il telescopio. Ininfluente in osservazione del cielo profondo (la sera verteva sul confronto tra il Vixen ED130-SS e il binoscopio da 13 cm.) l'elasticità della struttura diventa deleteria in alta risoluzione. Ho quindi fatto "miracoli" per allineare e "stakkare" i frames e il risultato è stato molto aiutato non tanto dai wavelets di Registax (usati quasi nulla) quanto dai filtri di fotoritocco che hanno interessato però solemente i gradienti e le tonalità, illuminazione, contrasto, maschere sfuocate e un ovvio resize di alta percentuale. E' un risultato, quindi, "aiutato" (come del resto fanno tutti gli astroimager) che però, almeno a mio modo di vedere l'asytronomia, è un po' "falsante".

Come in altre foto:

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.
