There's a lot of OIII in 2070, but there's also a lot of Ha. Depending on CCD sensitivity to each wavelength, the colour of the big spider can be anything from red to blue.
This shot is with a CLS on a full spectrum DSLR which lets a lot of Ha through so it ends up red. If you had your Nex3 full spectrum modified, it would let through a lot more red Ha.
There's no right or wrong colour, just a personal preference.
