Bonjour.
\nJe suis en cong\u00e9 pour 3 semaines, ce qui explique mon absence pour les activit\u00e9s du mois d’Aout.
\nVeuillez m’excuser.
\nA part \u00e7a je vous pr\u00e9sente une image solaire de ce 11\/08 faite en montagne o\u00f9 je s\u00e9journe.
\nCe n’est pas l’image du si\u00e8cle mais son principal int\u00e9r\u00eat r\u00e9side dans la modestie du mat\u00e9riel utilis\u00e9.
\nPST sur un tr\u00e9pied photo, avec une cam\u00e9ra ASI 174 MM.
\nSans Barlow il n’est pas possible d’obtenir la mise au point.
\nNe disposant que d’une powermate x 2.5 qui allonge la focale 1 m\u00e8tre, la mise au point devient possible,
\nmais le soleil est alors trop grand pour le capteur et l’image finale est donc une mosa\u00efque de 2 images.
\nConclusion rassurante : il est donc possible de faire des images +\/- correctes avec un mat\u00e9riel relativement abordable.<\/p>\n

Donn\u00e9es techniques :<\/p>\n

focale 1 m\u00e8tre
\nEchantillonnage 1,2 sec arc\/pix
\nPouvoir s\u00e9parateur du PST: +\/- 3 sec arc<\/p>\n

Gain=0
\nExposition=9,0500ms
\n2 Films de 14,376s
\nCadence 103 images par secondes
\nEmpillement de 100 images avec AS3
\nOndelettes 3 niveaux Registax
\nFusion des 2 images, renforcement, tons clairs tons fonc\u00e9s, colorisation sous Photoshop.
\nBien \u00e0 vous.
\nMarc.<\/p>\n
