About this object
WR 134 is a Wolf-Rayet type star 6,000 light years distant in the constellation Cygnus which is surrounded by a faint bubble nebula created by the intense radiation and stellar winds from the star. WR134 is classified as an Algol type eclipsing variable and given the designation V1769 Cygni. The star is the whitish one near the center of the bubble. WR134 is extremely hot at 63,000K and is 400,000 times as luminous as our sun. In this image the bubble is shown in doubly ionized oxygen light (OIII) as the round blue/green area just above center. It takes on a brighter radiating look towards the bottom of the bubble and a more wispy look above that. It seems to almost form a nice circle. Other doubly ionized oxygen emission is scattered in faint streaks and permeates the entire right hand side of the image. Also the area is full of Hydrogen (HII) emission shown as the red clouds of gas. Two faint reflection nebula designated GN 20.10.7, right next to each can be seen below and to the left of the main OIII bubble. Another reflection nebula called GN 20.03.0 is located on the lower right side of the image. Several open star clusters, dark nebula and other named objects can be seen in the annotated image.
The image is a rotated north up and east to the left. Clicking on the images will display a full resolution view. The image combines 4hrs of RGB exposures and 27.3hrs of HII and OIII exposures for a total exposure time of 31.3hrs. Image resolution is 1.61 arcsec/pixel. The image was taken at the 2024 Okie Tex star party with a Stellarvue SV80S 80mm refractor and a ZWO ASI 2600 MC pro color camera on a ZWO AM5 mount. A dual narrowband 5nm Antlia ALP-T filter was used for the Ha and OIII emission.
