Puppis A Supernova Remnant - Chandra/ROSAT insert

Link: https://www.astrobin.com/340254/G/?image_list_page=2&nc=&nce=

The Puppis A supernova remnant is a messy cosmic calamity approximately 7,000 light years away. It overlaps the Vela Supernova Remnant, but is four times further away.

A reprocessed version of this image is posted separately on Astrobin. This version includes an insert of a composite x-ray/optical image (Chandra, ROSAT et al) of the region (intended for mouse-over IDC)

The Chandra/ROSAT image shows a so-called 'cosmic cannonball', a neutron star (RX J0822-4300) ejected at an incredible 3-5 million kph by the supernova explosion. The 'cosmic cannonball’ is within the field of view but not visible in my optical image.

Exposures: 24.5 hours. 9.5 hours Ha. 13.5 hours OIII. 1.5 hours RGB.

This image was processed in PixInsight using a bicolor palette (Red = Ha, Green = OIII, Blue = OIII x 1.1). Short-exposure RGB image data was blended with stars in the NB image. The final image was re-sampled by 120% for aesthetic reasons.

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.
