Vela SNR - SHO (Matt Hughes)

Vela SNR - SHO

I've been wanting to image the wider Vela SNR since I originally took a picture on a much smaller section of it last year.
This is a 4 panel mosaic that came in at 1.1 Gb. My computer was having conniptions processing the four panels from the IMX455 sensor, and pixinsight and photoshop crashed at least once each (my monitor nearly had a fist shaped hole in it (don't kill the messenger...))
The four panels were taken over about a 6 week period from 17 Dec 2022 to 26 Jan 2023. I was fighting the clouds, and the moon illumination for the OIII data, so it took a while for the moderate integration time. Working with the FSQ106 and its 0.72 reducer improved the speed of the scope one stop, which helped. Each panel had about 6 to 7 hours of data spread approximately even amongst the 3 filters.
The weather was up and down a bit over the last month and I planned originally to include LRGB but decided to just do the SHO palette as time was running out. I may revisit the target next year to include the LRGB.
I find this region so fascinating. The 4 panels encompass approx 10 degrees by 6.5 degrees. The vela SNR's source was a Type II supernova which exploded approximately 11,000–12,300 years ago (and was about 800 light-years away). This widefield image includes other SNRs but the Vela dominates.
I reduced the size of the stars to try and bring the nebula out. Since its a false colour SHO image, I thought there was no obligation to have the stars stand out as much. I might be wrong.
I hope you like my rendition of the Vela SNR.

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.
