Sh2-129 Flying Bat Nebula and Squid Nebula, Cepheus
DESCRIPTION: I tested to capture Squid nebula - very fine blue object in the center - but unfortunately not successful. More data needed, maybe blue light pollution filter destroyed this object, maybe OIII filter is needed. “Artistic” processing via StarXTerminator.
