Description: Bright, oval-shaped nebula, a “dumbell” elongated in W-E direction. The brightest part of the nebula is the western “wing” of the dumbell. There are also a fainter extensions of the nebula, which becomes visible with UHC -filter and averted vision. When gazing the nebula with the filter and undirect vision, it becomes clearly oval shaped, and it’s length axis turns to NW-SE -oriented. The southern extension is brighter than the northern one. There is a relatively bright star in the NW edge of the nebula.
