SH2-129 is a larger emission nebula complex in Cepheus that is dominated by H-alpha emissions. Ha makes the red background of this image. In 2011 a very faint OIII emission nebula structure was found by Nicolas Outters. OU4 is resembles to a squid which lead to the name of the nebula.

The image is a combination of image data shot with my 80/480 mm refractor with 0.79 x reducer for the field (=380 mm). The Squid data come from the 130/910 mm refractor which I originally had used to image only OU4.

80 x 200s Ha (480 mm)
63 x 300s OIII (910 mm)
