The galaxy NGC 2841 has an active core where star formation is taking place and tightly coiled, fluffy spiral arms.
Near NGC 2841 lies HD80606 (the lower of the binary star on the left in the image), which contains an interesting exoplanet.
I photographed this interesting object several years ago, unfortunately only in black and white:

Several of the subframes were affected by clouds. The glow in the right-hand corner of the frame is from a 6.2 mag star just outside the field.
Near NGC 2841 lies HD80606 (the lower star of the double in the left of the frame). HD80606 is orbited by a very interesting exoplanet.
