Voil\u00e0 le secret! Pendant des ann\u00e9es, je me suis demand\u00e9 comment faisaient des amateurs munis d’instruments parfois nettement plus petits que mon C11 pour avoir les r\u00e9sultats qu’ils obtiennent; et voici qu’enfin le secret m’es r\u00e9v\u00e9l\u00e9. Bon, la d\u00e9convolution, ce n’est pas nouveau, sauf que moi, je restais b\u00eatement \u00e0 faire la mont\u00e9e d’histogramme puis quelques petits r\u00e9glages de luminosit\u00e9, contraste et accentuation et c’\u00e9tait tout. L\u00e0 c’est autre chose! \u00c7a rigole beaucoup moins et je peux enfin obtenir des r\u00e9sultats dignes de ce nom!
\nVoici donc quelques exemples d’anciennes images retrait\u00e9es (vous en avez d\u00e9j\u00e0 eu un aper\u00e7u il y a quelques jours avec l’image de NGC2261)<\/p>\n

B33 – Un dada qui p\u00e8te le feu:<\/p>\n

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

NGC2359 – Le casque de Thor pour monter le dada en toutes s\u00e9curit\u00e9:<\/p>\n

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

Et comme le printemps arrive chaque ann\u00e9e un peu plus t\u00f4t, les n\u00e9buleuses plan\u00e9taires fleurissent elles aussi plus t\u00f4t:<\/p>\n

NGC6543 et sa corolle:<\/p>\n

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

M57 et sa corolle:<\/p>\n

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

Abell21. Moi, j’en reste m\u00e9dus\u00e9!<\/p>\n

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

Voil\u00e0, ce sera tout pour cette fois.
