M27 a colorfull balloon
My m27 Image done with a (QHY8 (color CCD)=(Europe: Alccd 6c)) and a 10" Astrograph f3.8 (Astro Systeme Austria).
At this time the Astrograph (10inch ASA) and his corrector has not the exact distance to the surface from the chip. Next week I will reduce the distance and then the stars should be only 1/3 of diameter. = more Details and more sharpness.
