Feb-Mar 2003

Notizen: I have shot NGC 2903 now for three years in succession, but there's some improvement every year. I wonder if this works infinitely ;-) I combined the red colour channel with a Ha image as the (old, they have a revised version now) Astronomik Type II colour filters don't bring out HII regions well. The combination of background smoothing and maximum entropy deconvolution to tackle elongated stars left somerings around bright stars. Taken from the middle of Berlin with an 8" LX200 at f/6.3, MX716 camera, video autoguider, 22x10 minutes for L, 2x5 minutes 2xbin for RGB.
