Ammasso doppio di Perseo

Primo test di aumento del tempo di integrazione e seconda elaborazione con PixInsight. Soggetto relativamente semplice, dove ho però rischiato di non concludere nulla per via di alcune nuvole pericolosamente vicine al soggetto di ripresa. Fortunatamente hanno solo lambito, e le foto ottenute sono apparse "pulite".

Il lavoro effettuato con PixInsight è stato migliore rispetto al primo approccio con NGC6960, ma sono ancora ben distante da un utilizzo che reputo sufficiente. In particolare non sono riuscito ad eliminare dalla foto finale i puntini di stelle più piccoli per ottenere un'immagine più pulita, e devo sicuramente lavorare sulla nitidezza dell'immagine (sebbene quest'ultimo aspetto credo dipenda anche dalla qualità delle riprese effettuate e della necessità di mettere meglio a fuoco).

Pultroppo, a causa di un mio errore durante le riprese, ho dimenticato di effettuare i Flat Field. Per la precisione sono passato al soggetto successivo della serata, le Pleiadi, prima di riprenderli; siccome però per centrare meglio M45 ho ruotato la macchina collegata al tubo, di conseguenza ho reso impossibile riprenderli per l'Ammasso doppio. Fortunatamente, PixInsight ha ridotto in parte i problemi derivanti da questa mancanza.

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.
