This picture required a longer post-processing time due to the limited time integration used.

Tipically, I use over 60 hours of integration, but in this case, the integration time was only about 22 hours (even taken at f3.3).

I am planning to take more frames on narrow band this year to capture additional details.

Nevertheless, this image represents the first version captured during the previous summer.

I hope you like it.

 

WR 134 is a variable Wolf-Rayet star located around 6,000 light years away from Earth in the constellation of Cygnus, surrounded by a faint bubble nebula blown by the intense radiation and fast wind from the star. It is five times the radius of the sun, but due to a temperature over 63,000 K it is 400,000 times as luminous as the Sun. (credits wikipedia)
