WR 134 (HOO)

WR 134 is a star located in Cygnus approximately 6,000 light-years away. It is a special type known as a Wolf-Rayet star, which releases intense radiation and strong solar winds carrying its outer layers. The star (HD 191765) is the bright yellow star sitting between the two bright blue stars in the center of the nebula. The blue arc was produced when the radiation and particles from the outer layers collided with the ambient nebula already in the region. The blue oxygen rich region is strongest in the upper left portion where it forms the arc, it is visible surrounding the star forming a bubble.

I really love this region and will most likely be back with different equipment. Most objects have an optimal focal length (magnification + field of view) with what looks good, however, this object in particular looks good at many different focal lengths from 400mm to 1400mm which is what I used with the 0.7 focal reducer. I processed this emphasizing HOO, but again, there are many fantastic different versions out there.

As usual I would have loved to get more time on it especially since it was with a OSC camera, in fact I was out there many nights wading through supposedly clear nights, however, I am happy with the image. This is one object I would definitely put on anyone's to-do list who has an OIII filter since it can be imaged well with any telescope but you may need to block out some time as it is dim.
