Big green spider and possibly (probably?) SN1987A

Here's my take on the Tarantula Nebula, taken over a couple of pretty warm hazy nights in Sydney with my new scope. It's un-modded DSLR, so as usual the OIII emission from the Tarantula region swamps the H-alpha making it green, but I'm pretty happy with the sharpness and resolution for the most part. I think I've resolved the SN1987A remnant too. I'm also learning a lot more about PixInsight now, and beginning to implement some better noise reduction methods with masks. All that said, comments and criticisms most welcome, you guys are usually a good tough crowd ! I'll be interested to hear if you reckon I'm being wishful in thinking the pinkish smudge between the two stars is the SN remnant .

19 x 300s, 4 x 180s, 38 x 90s, 200mm f/5 Newtonian, EOS 60D, HEQ5 Pro & thin OAG/StarShoot Autoguider, processing in PI.
