Twin Crescents and Bypass

First light with an ASI2600 camera and some other equipment upgrades. I'm quite impressed with the extra sensor size, dynamic range, and other new features. Kudos to Sony and ZWO for the step improvement.

This portion of the Vela Supernova Remnant is quite faint, which may explain the scarcity of examples on AstroBin. The oxygen filled shockwave fronts to the left of frame are known as the Twin Crescents. The vertical filament to the right, known as the Bypass, is tightly defined at the top, then rapidly diffuses below. The young cluster right of centre is NGC 2659

This HOO image with RGB stars took lots of work to remove moonlight gradients without destroying nebulosity, but I got there in the end. I'm enjoying exploring the Vela SNR which is turning out to be quite varied.

Thanks for taking a look.
CS and good health to all!

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.
