NGC 253

La galaxie du Sculpteur NGC 253 en Octobre 2017 à l'observatoire Astroqueyras de St Véran (France- Alpes)

RC 500 f/8 Astrosib

AP 1600

Apogee U16000

Toujours dans le traitement des données de ce séjour d'octobre 2017. A l'epoque je n'avais pas reussi à en tirer quelque chose de satisfaisant, c'est un peu mieux aujourd'hui.

Celle ci est très basse sur l'horizon en France et la résolution (FWHM) en a donc souffert. De plus elle n'a bénéficié que de 1h30 de poses mais content de l'avoir tout de même immortalisée.

Still in the processing of data from this stay in October 2017. At the time I had not managed to derive anything satisfactory from it, it is a little better today.

This object is very low on the horizon in France and the resolution (FWHM) has therefore suffered. In addition, it only benefited from 1h30 of poses but still happy to have immortalized it.

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.
