\nMy wide filed setup is based on a DSLR (40Da) coupled to a camera lens (f2.8 F200m). Well suited to the wide field on the Milky Way, this system is very limited in narrow band imaging. The optical path between a canon lens and the sensor is short, making it difficult to use a filter wheel.<\/em><\/p>\n

Voici une image test d’un nouveau setup: un objectif photo Hasselblad de F150mm coupl\u00e9 \u00e0 une CCD \u00e0 roue \u00e0 filtre, QSI583.
\n20×5 minutes de poses, avant le coucher de l’objet, en Ha.
