The Lions Head Nebula - Hubble Palette (LBN471) - with Spitzer IR Overlay (Eric Coles (coles44))

The Lions Head Nebula - Hubble Palette (LBN471) - with Spitzer IR Overlay

This is the result of data collected over a three-year period. I will be presenting one part of the processing used (the Tone Map), Sunday night, August 8, 2021, on The Astro Imaging Channel. You can watch it live on YourTube, or later as part of the recorded program. Hope to see you there. Eric

Revision: I noticed that this FOV contained the Wolf-Rayet star HD 211833 and thought it would be interesting to represent some additional imagery showing the effects of this unique star. To that end, I assembled an image from the Spitzer_SHA data archive found in the MAST Portal. There were various images showing the structures emitting IR radiation. I chose those that were most dramatic. The image shows that section of the nebula where Spitzer data was available. The highlighted area is a three-panel mosaic of Spitzer information. Those data were mapped on the Hubble Palette image as a deep red color enhancement to come as close to IR as our visual spectrum allows. The WR star is also noted on that image.

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.
