I present you my last acquisition since the setup HAO_4. these are two nebulae including one (Ou4) discovered by my friend the French astrophotographer Nicolas Outters in June 2011. This is the Giant Squid (in blue/green in the image) which is a bipolar planetary nebula located about 2000 light-years from Earth surrounded by the Flying Bat Nebula (cataloged Sh2-129 in red), both are located in the direction of the cepheus constellation.
