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.
