Description

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.
