This picture has captured a very minor and indistinct planetary nebula lying in western Hydra. The nebula is positioned about 1 degree south of iota Hya, fairly large one with a diameter of 4.5 arc minutes but very dimmer brightness about 13th magnitude, perhaps you cannot detect it even if you can use larger ranged telescopes. A 7th magnitude star is glittering just southwest edge of the nebula, this star obscures the clear figure of nebula through our own eyes. This image barely shows you a greenish blued round shape of the nebula but cannot detect detailed inner structure.
