Description

I tried to take a picture with the C11 which did not work due to reflections in the corrector lens as well not in the SW 120ED (did not resolve the LEo 1). Now with the Sharpstar Astrograph the next trial which was surprsingly easy in spite of the small integration time. The picture is slightly cropped!

Description: Leo1 picture taken with the C11. Regulus is shining heavily into the field of view. D5100 at1600 ASA and 136min at f2100mm. I made a pciture with the SW120ED Refraktor as well, but this did not resolve Leo1 into stars.

Description: New processing with better details. Its interesting to compare the new picture with the C11 pciture.
