Leo Triplet
18:54 13/3/2007 UTC
< Previous Next >Pretty lousy transparency during this session. Leo is in the most light polluted parts from my backyard at this time. Light pollution and transparency equals low signal to noise ratio, so nothing spectacular came out despite of rather long exposure. Leo Triplet galaxies are rather small in my equipments FOV. This image is cropped from the full resolution version.
