NGC 3338

NGC 3338 

Spiral galaxy NGC3338 belongs to the Leo II group located about 70 MLY from Earth, it is very nice spiral with well defined arms, but only seldom photographed.
I also marked here two bright quasars just to the right of the galaxy, with redshifts z=1.76 (the lower one) and 1.09, i.e. the light travel time was 9.98 and 8.165 Gyr.

After ten years, there is (finally) a new version of the photo here, after another almost three hours of exposure (L-only) and some post-processing. It’s significantly better than the first version; I really like it now, even the simple composition.
