Back to the deep sky with this rarely photographed field, still from my backyard in the Paris region.
It covers an area going (on the left) from the planetary nebula LoTr 5 discovered in 1980 and located at a distance of 1650 light years, up to the beautiful spiral galaxy NGC 4725 located at 41 million light years (on the right ).
To the left of NGC 4725, an elongated galaxy: NGC 4747 located 45 million light years away.
On the right, a galaxy almost five times further away, NGC 4712 at a distance of 200 million light years.
