Sh2-129 and OU4

Object Sh2-129; OU4; "Flying Bat and Squid Nebulae"
Description The red (Ha Signal) is sh2-129, the flying bat nebula. The blue squid nebula (OIII signal) in this image (OU4) was discovered by the French Amateur Astrophotographer Nicolas Outters in 2011. It is very faint. I used a tone mapping process originally described by J-P Metsavainio to bring it out. All the data was collected on my summer road trip to see the total eclipse of the sun.
