WR 134 Variable Wolf-Rayet (Richard H)

WR 134 Variable Wolf-Rayet

UPDATE August 2021:
With too many wildfires around us for the past several weeks I went back to some previous images to reprocess with some updated techniques I learned. I found some additional raw data for the above image. I processed the data to bring out more of the nebulosity of the cloud, star detail and reduction of background noise levels. The increase in the number of frames contributed to the overall final picture.
Frame now total;
Sii 125 x 180s
Ha 125 x 180s
Oiii 124 x 180
Total of 18.7 hours integration time

Original information from September 2019
A very faint and difficult target to image. At a magnitude of 8.08 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 - Wikipedia

Due to not-so-kind amp glow from the Panasonic sensor in the ASI 1600mm Pro cooled CCD camera that Flat frames would not work I only used bias calibrated dark frames to get rid of the amp glow with no need for flats. This camera is set at the factory with a fixed offset of 50.

bias frame master (300 frames) @ 0.2s ea to calibrate 50 dark frames G139 @180s ea
Sii Astronomik filter 78 frames G139 @ 180s ea
Ha Astrodon filter 81 frames G139 @ 180s ea
Oiii Astrodon filter 72 frames G139 @ 180s ea
Total integration time: 11.55 hours

Description: Too much smoke in the air to image so I'm reprocessing some old data. This was imaged back in 2019

Description: Second and final revision.
Added additional frames from another image session to bring out the nebulosity, reduce noise , balance colors, reduce star size/brightness.

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.
