M33 Triangulum Galaxy (First light)

This is the first light with the 4 inches telescope. The focussing works well in spite of its tight CFZ at f/3.65. The optics are approx. 3 times faster than my previous FS102@f/6. Well, the results look quite promising, although the FOV with the old ST7 is very small indeed. It is less than 1°. The photo is taken during the full moon phase. Hence, strong gradients are detectable in this photo. The color versions are composites of Red=3x3min, Green=3x3min, Blue=3x4min, L=10+3*3min.
