WR 134

Constellations: Cygnus

WR 134 is a variable Wolf-Rayet star in the constellation of Cygnus. WR 134 is surrounded by a faint bubble nebula blown by the intense radiation and fast wind from the star. Link to interactive sky chart.

Date:

This image was taken during several nights in July, August and September 2022. It was captured with Hydrogen-α and Oxygen-III narrowband filters.

Telescope & Mount:

Takahashi FSQ-106ED on a Paramount MX+ mount

Imaging:

Camera: ZWO ASI2600MM Pro (bin 1×1)

Data:
Hα: 64x300s
O-iii: 181x300s

Total integration time: 20h 25′

A closer look at the faint blue nebula around WR 134.

For this image the following equipment was used:

Telescope: Planewave 17″ CDK f/6.8 Dall-Kirkham on a Planewave L-500 Fork Mount.
Camera: Kepler KL4040 CMOS (bin 1×1)
Data: Hα 12x600s and O-III 148x600s. Total integration time: 26h 10′

WR 134 is the redish star below the middle of the image.

Also, I have noticed a blue-green “spot” to the west of the blue nebulosity, towards the edge of the image. Upon closer inspection, this could be a planetary nebula. However, none of the catalogues fo péanetary nebulae mention one in this position. I am investigation further …

The image below was taken with my Celestron C9.25″ on a 10Micron GM1000HPS mount. Data was acquired with a ZWO ASI2600MM-Pro and an Antlia ALP-T Dual Band 5nm Highspeed filter: 215x120s for a total integration time of 7h 10′.

The image was framed to include the region to the west of WR134 and also capture WR133.
