NGC 7479
(also known as
Caldwell 44)
is a barred spiral galaxy about 105 million light-years away
in the constellation Pegasus. It is also recognized as a
Seyfert galaxy and a LINER undergoing starburst activity not
only on the nucleus and the outer arms, but also across the
bar of the galaxy, where most of the stars were formed in
the last 100 million years. (wikipedia) With angular
diameter of about 3´ it is not an easy object for
photography, namely with relatively small scope. In addition
I had some unexpected problem witn L-channel and so this picture
is not yet optimal (but existing..)
