Bonjour \u00e0 tout le monde,
\nEquip\u00e9 d’un C11 (280mm de diam) ouvert \u00e0 F\/D 6.3 gr\u00e2ce au correcteur\/r\u00e9ducteur Celestron, j’utilise une zwo asi 1600 mc pro pour les captures.
\nEntre le r\u00e9ducteur et la cam\u00e9ra, j’ai un adaptateur que j’ai imprim\u00e9 en 3D => https:\/\/www.thingiverse.com\/thing:4336552<\/a><\/p>\n

Je dois reconna\u00eetre que le concepteur a \u00e9t\u00e9 tr\u00e8s sympa et m’a bien conseill\u00e9 !<\/p>\n

J’ai serr\u00e9 (fort) l’adaptateur sur le correcteur et j’ai aussi serr\u00e9 bien fort la cam sur cet adaptateur.
\nMais j’ai peut-\u00eatre serr\u00e9 trop ou alors pas encore assez… Toujours est-il que j’ai des soucis.
\nVoici une photo de M51 – 30 poses de 150 sec.<\/p>\n

\"\"<\/a><\/p>\n

La cause de la mauvais qualit\u00e9 de la photo est peut-\u00eatre simplement due \u00e0 une mauvais collimation mais je n’en suis pas certain.
\nA votre avis, est-ce un probl\u00e8me de collimation et\/ou de tilt \u00e0 cause de mauvaise impression\/serrage de l’adaptateur.
\nOn voit que c’est tr\u00e8s fort aux 4 coins bien que un peu moins (il me semble) dans le coin inf\u00e9rieur gauche.
\nQuel est votre avis ?
\nMerci d’avance de votre aide.<\/p>\n\n\n
