About this image

Decided to capture Wolf Rayet 134 in the Constellation of Cygnus.

This object is around 6000 light years from Earth and is a target at an advanced

Stage of evolution. Expelling its mass Into space at a high rate soon to go Supernova

Rayet stars are quite rare and not always easy to locate and image.

Interesting to see WR134 in its environment. (And its unexpected colour, with the extremely hot star surface hidden by the thick high velocity stellar wind so appearing off white in the image rather than blue). This star was the subject of a pro-am collaboration a few years back using spectroscopy to study the structure in the winds of WR stars.

Thanks for the coment shot in Ha and Oiii the Ha I added to the red channel

and the Oiii to the blue and green channels, hence the colour is off.

The colour is probably about right. The spectrum continuum of the wind is pretty flat. There is He emission (not H alpha) in the H alpha filter passband and there is no significant emission from the star in the [OIII] passband so the star appears orangey white in H alpha [OIII] NB images

Cheers
