Les vacances sont finies, les soir\u00e9es se rafraichissent mais pas de quoi d\u00e9courager les astrophotographes et dessinateurs de l’association ! Alors c’est parti !<\/p>\n\n\n\n

Didier a \u00e9t\u00e9 le premier \u00e0 nous envoyer sa prise de vue de M31.<\/p>\n\n\n\n

\u00ab\u00a0Bonsoir \u00e0 tous\u2026 Petit clich\u00e9 de M31 pris en une seule session, cette nuit. Prise en LRVB avec 12x300s en luminance, et seulement 3x300s par couche RVB. ASI1600MM sur ASKAR FRA400 +r\u00e9ducteur le tout sur EQ6 R.\u00a0\u00bb<\/em><\/p>\n\n\n\n

Voici la belle r\u00e9colte de Simon Pierre. Avec un descriptif pour chacune ce qui est toujours int\u00e9ressant.<\/p>\n\n\n\n

\u00ab\u00a0Chers amis. Premi\u00e8re lumi\u00e8re de mon nouveau SW150\/600. Voici NGC7380, la n\u00e9buleuse du sorcier. Situ\u00e9e \u00e0 environ 7500AL dans la constellation de C\u00e9ph\u00e9e. Il s\u2019agit d\u2019un grand nuage de gaz, essentiellement compos\u00e9 d\u2019hydrog\u00e8ne, au sein duquel se forme de nouvelles \u00e9toiles, et qui se trouve ionis\u00e9 par le rayonnement de ces derni\u00e8res. Ici, vous avez 688 poses de 30 secondes. Soit 5h44mn au total. J’ai sorti toute l’artillerie. ASIAIR, EAF, ASI533MC, ASI290MM (pour le guidage), filtre Optolong L-PRO. Traitement avec SiriL uniquement. J’arrive enfin \u00e0 quelque chose de potable. Que voulez-vous, je comprends vite, mais il faut qu’on m’explique longtemps. L’image jpeg est bien d\u00e9grad\u00e9e, je vous la montrerai plus tard en TIFF. Cette derni\u00e8re fait 62,8 Mo. Astronomicalement.\u00a0\u00bb<\/em><\/p>\n\n\n\n

La version TIFF est disponible ici<\/a> mais il faut \u00eatre inscrit sur le forum.<\/p>\n\n\n\n

\u00ab\u00a0La n\u00e9buleuse de l\u2019Iris, NGC 7023, aussi nomm\u00e9e Caldwell 4 et la n\u00e9buleuse de l’Iris est une n\u00e9buleuse par r\u00e9flexion dans la constellation de C\u00e9ph\u00e9e. Elle est situ\u00e9e \u00e0 1300 ann\u00e9es-lumi\u00e8re de la Terre.<\/em><\/p>\n\n\n\n

Cette image a \u00e9t\u00e9 r\u00e9alis\u00e9e avec ma lunette Omegon 72\/432. Apr\u00e8s ma belle image qui \u00e9tait r\u00e9alis\u00e9e avec mon SW150\/600, je dois avouer que je suis un peu d\u00e9\u00e7u. Clairement, le bon back focus du correcteur de champ n\u2019est pas respect\u00e9. J\u2019ai \u00e9galement utilis\u00e9 l\u2019ASIAIR et la cam\u00e9ra ASI533MC. Cependant, avec cette lunette, je ne peux pas utiliser l\u2019EAF. J\u2019ai donc d\u00e9cid\u00e9 d\u2019\u00eatre tr\u00e8s restrictif question FWHM. Je pouvais faire \u00e7a, car j\u2019ai mis le paquet question temps de poses.<\/em><\/p>\n\n\n\n

Apr\u00e8s quatre nuits de captures, j\u2019ai obtenu un total de 1925 images de 30 s, soit 16 h 02 mn 30 s.<\/em><\/p>\n\n\n\n

Tri manuel avec le navigateur (nuages, satellites, avions) : reste 1830 images = 15 h 15 mn.<\/em><\/p>\n\n\n\n

S\u00e9lection d\u2019images manuel sous SiriL (FWHM) : reste 1675 images = 13 h 57 mn 30 s.<\/em><\/p>\n\n\n\n

Tri automatique SiriL (rondeur des \u00e9toiles) : reste 1508 images = 12 h 34 mn.<\/em><\/p>\n\n\n\n

Je n\u2019avais pas encore re\u00e7u mon nouveau Newton mais cette cible m\u2019int\u00e9ressait. Je vais donc retenter l\u2019exp\u00e9rience avec mon nouveau set up.<\/em><\/p>\n\n\n\n

Bon, je vous la montre quand m\u00eame. Evidemment, la TIF est plus int\u00e9ressante mais l\u00e0 aussi, elle fait 47 Mo.<\/em><\/p>\n\n\n\n
