Boomerang Nebula, the coolest place in the Universe

Hi all
Heres an image of the Boomerang Nebula in Centaurus. Taken last Sat night with my 10 inch f5.6 Newtonian and Hutech modded 350D camera. Ive included a full frame view and a full resolution crop.

5x10 mins ISO200. UV/IR filter, Baader MPCC coma corrector. Hand off axis guided with Q guider cam as usual.

This is an odd protoplanetary nebula

Its actually colder than the cosmic background

Its an odd colour too, a yellow white, seeimgly more broadband emission than emission line, hence I didnt use a nebula filter only the uv/ir filter.
Its small and faint, would be a good visual challenge for the big dob users.
