L’asteroide geocroiseur Toutatis a ete observe et photographie par Jean-Luc Dighaye le 17 septembre a 21:10, 21:30, 22:00, 22:20. Les images ont ete realisees au foyer primaire de la lunette apochromatique (D\/F=200\/1600) et un appareil numerique Nikon D100 (ISO 1600), donnant un FOV = 30′.
\nLes 4 images ont ete additionnees et on voit ainsi l’asteroide (les 4 points alignes au centre de l’image) se deplacer (tres vite!) sur le fond du ciel etoile.<\/p>\n

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

Au cours de la meme nuit les nebuleuses planetaires compactes NGC6826 (Blinking nebula) et NGC7009 (Saturn Nebula) ont ete photographiees avec le meme equipement (respectivement a gauche et a droite dans l’image ci-dessous). Dans les deux cas compositage de 4 images de 30s a ISO 1600 (FOV 10′).
\nLa premiere a une enveloppe parfaitement circulaire alors qu’on apercoit des details tres subtiles dans la nebuleuse \u00ab\u00a0Saturne\u00a0\u00bb. Pour ceux qui connaissent cette derniere les extensions laterales (a droite et a gauche) sont meme tres faiblement visibles ! On apercoit aussi facilement dans les deux cas l’etoile centrale (naine blanche). On notera egalement la couleur typique tres bleutee de ce type de nebuleuse. <\/p>\n
