WR 134 (Lee Dodge)

WR 134

From Wikipedia: "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."

The nebulosity of this object is low, and it was increased in this image by reducing the intensity of the stars and increasing the intensity of the nebulosity.

The night sky at the location where the image was taken is dark, with a typical Sky Quality Meter measurement of 22.25 MPSAS, equivalent to a Bortle rating of 1. However, being on the lee side of the Continental Divide at an altitude of ~8600 ft. (~2600 m), the air is not particularly stable, and the FWHM values for these images were mostly 2 to 3 arcseconds, with some of the narrow band images less. Images with larger FWHM values than 3 arcseconds were ignored. BlurXTerminator from RC Astro was used to reduce the star diameters and star halos, and StarXTerminator was used to remove the stars to process the nebulosity separately from processing the stars. Star colors were taken from RGB filter data, and then adjusted by PixInsight's Spectrophotometric Color Calibration (SPCC) routine. Colors of the nebula were based on RGB data corrected by SPCC (along with the stars), and then combined with Halpha and OIII measurements using PixelMath in PixInsight. The light intensity from the stars was arbitrarily reduced relative to the nebula using PixelMath.

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.
