W.Bond Crater 18 Aprile 2013 20:04 U.T.

Per quest'immagine sono stati utilizzati 140 frames totali di 6/10 di seeing scelti su 1101. Come sempre valuto il seeing in funzione dei frames che sommo. Sarebbe ridicolo (come alcuni fanno) giudicare l'intero filmato e quindi momenti anche di seeing da 1/10!

Sono personalmente molto soddisfatto di questa immagine. Il motivo risiede nella mia continua attenzione verso le flebile "Rima W. Bond". Come ben vedete, anche dalle varie mappe LROC, la rima in questione "taglia" quasi orizzontalmente il grande cratere W. Bond. In realtà la mia personale ricerca, in tanti anni di riprese, era dedicata al primo tratto (verso Ovest) della rima, la parte di colore più scura. Questa volta sono riuscito a risolverla tutta e la forma a "V" ha preso posto a quella classica orizzontale. Normalmente si risolve facilmente il secondo tratto verso Est di colore chiaro. Ma il primo viene risolto difficilmente e raramente. Insomma dopo anni di caccia...ci sono riuscito!

Detto questo il cratere in questione è uno dei più antichi. Molto grande e piuttosto livellato. All'interno sono presenti molte strutture: craterini, rimette, altopiani. E' davvero carico di dettagli e questo suo particolare aspetto(piano e carico di dettagli) lo rende quasi unico e davvero molto interessante.

A Nord-Ovest troviamo il grande cratere Epigenes quasi completamente in ombra. A Sud Ovest sempre in ombra, c'è il più piccolo Timaeus mentre a Sud, in fondo all'immagine, si trova Archytas con la frastagliata muraglia Ovest del cratere in ombra.

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.
