M45 Poss II DSS

Il primo Osservatorio Palomar Sky Survey (POSS I) è stata effettuata sulla Oschin Schmidt Telescope nel 1950-1957 con piastre 103aO e 103aF. POSS I continua ad essere una delle risorse astronomiche più frequentemente utilizzati; di carta o di vetro copie delle lastre si trovano nella maggior parte degli osservatori del mondo e una versione digitalizzata è disponibile on line dal Space Telescope Science Institute.

Durante il 1970 più fine grano, emulsioni veloci si sono resi disponibili dalla Kodak Corporation. Il Regno Unito Schmidt (che è una copia virtuale del Oschin Schmidt, ma con un correttore acromatica) ha effettuato una Sky Survey del sud con piastre IIIaJ e IIIaF. Nei primi anni 1980 si è deciso di aggiornare il Oschin Schmidt con l'installazione di un correttore acromatica e la fornitura per autoguida. POSS II è stato progettato come complemento nord al sondaggio UK Schmidt con 897 piastre in ognuno dei tre bande di frequenza su IIIaJ (blu), IIIaF (rosso) e IVN (vicino infrarosso) piatti, rispettivamente. Fondi consistenti per l'aggiornamento del telescopio e l'esecuzione di POSS II sono stati donati dalla Alfred P. Sloan Foundation, la National Geographic Society e attraverso una serie di sovvenzioni dal National Science Foundation. La società Eastman Kodak ha fornito tutte le piastre per POSS II, oltre a una sovvenzione diretta in denaro.

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.
