Vela SNR Highway

I currently have some vacation time allowing me to stay up all night, sleep all day, and complete a few imaging projects.

This is an attempt at the "Highway" section of the Vela SNR, the remnant of a massive star that exploded around 12,000 years ago towards the end of The Stone Age. It spans approximately 8 degrees by 8 degrees making it ~16 times the apparent diameter of our Moon. Expanding shockwaves from the SNR explosion compress and ionise surrounding material, generating regions of enhanced density and magnetic fields. These regions serve as conduits for the acceleration of ions and electrons, creating bright filaments of emission that trace the path of the magnetic field lines (Wikipedia abridged).

The Vela SNR is vast and complex, making it difficult to navigate.
@Gary Imm has provided an excellent annotated image and description of the region here.

The Ha signal in this region is particularly strong. During PixInsight processing I found GHS-stretched Ha and OIII a little overwhelming (revision C), so I reverted to more subdued Histogram Transformation STF stretching for my final version. I'm really enjoying the new Gradient Removal tool in PI which reduces processing effort, along with the excellent Russell Croman tools.

Thanks for looking and CS!

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.
