NGC 5907, the Splinter Galaxy, is very slender edge-on spiral galaxy with a small central bulge and a pronounced dust lane. The dust lane shows some wonderful detail and gives the core a beautiful amber color. The galaxy itself is something of a giant lying 59 million light years away and 180,000 light years across.
NGC 5907 is currently well placed high in the overhead during the early evening.
