A Progressive imaging set, WR134 (Jim Medley)

A Progressive imaging set, WR134

Revision title: Final version, no further updates

Wolf Rayet stars are primarily central stars of planetary nebula and WR 134 is no exception. This image was processed from data collected at the Sierra Remote Observatory, and represents about 50% of the total planned frames in H-alpha and O-iii, thus a work in progress. I pre-processed this using Astropixel Processor to generate the H-alpha image and the O-iii image then used BlurXterminator, GHS, and NoiseXterminator in Pixinsight before combining them to form the final HOO image. Then some cosmetic curve tweaks in Lightroom to provide the image here. We don't even have the full dataset yet, and the resolution of the planetary nebula is quite impressive. Thanks to Linda, Gowri, Tim, Bob and Chris at the PWO14 SRO team for allowing a novice to join your group and special thanks to Linda for coaching me through the intricacies and intimidations of PixInsight.

Title: RGB Stars added and additional H-alpha and O-iii data.

Description: We included about an hour each of RGB. I only included RGB for the stars in the background/foreground so they are not included in the overall acquisition time.

Title: The Eye of God

Description: Really starting to show the details in O-III. I am learning as I go and this version used Drizzle integration in APP for both H-alpha and O-III, prior to channel combination. Essentially a 2X drizzle which really flattened the field and cleaned up the noise. Though the file size is pretty unwieldy...

Title: Final version, no further updates

Description: With the remaining few O-iii and H-alpha frames completed, this was processed in Astropixel Processor, with background correction and vignette correction for both sets, then combined as HOO in APP. The final HOO file was worked up PixInsight with stars removed and careful stretching with GHS and Curves to get the maximum resolution on the O-iii colors, then using NoiseXterminator. The stars were added back from the RGB data set, not the HO sets. Some final aesthetic touches within Lightroom for cropping out the amp glo and adjusting the contrast and saturation by eye.

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.
