WR 134

I like this region in Cygnus. Since my OIII channel came out quite week because of light pollution, I decided to combine LRGB from my Lacerta APO 430 mm focal length with the Ha channel from my 420 mm Sharpstar astrograph. In my opinion it could be worse.

Clear Skyies,

Christian

Description: WR 134 is a Wolf-Rayet star in Cygnus which is around 6,000 light years distant. It shines at 400,000 times the luminosity of the sun. Intense radiation and stellar winds have created a bubble of gas around the star. Unfortunately it is OIII, too. My OIII channel is more then bad. So I didn't integrate it in this picture, for what I am very sorry. An ultra massive star is in progress to blow its gas layers with a velocity of 2000 - 4000 km/ s out. It is not exploded, though. The massive star had to loose at least 40% of its mass to become a Wolf-Rayet star. These stars have a specific " bump", mostly in the ultraviolett part of the emission spectrum. It is brought, not sharp and shows Fe III and He emission. Ha is allready blown away. It emitts heavier elements to its neighborhood. The outer shell makes a fusion process from He to C. The He atoms loose up to both electrons ( He2 fusion) because of the high photon radiation pressure and this is only found in such massive stars like the Wolf-Rayet stars. These stars are the most massive stars, we know and the end up in a super nova.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
