Nebular gases are displayed using an HSO color palette. Broadband RGB stars were blended into the starless narrowband image.

The western and eastern portions of the sprawling Veil Nebula are shown here in a single two-pane mosaic. I imaged these two regions individually during summer 2022. Over the recent winter break, I finally had some spare time to stitch them together into a single image showing a more-encompassing view of the object.

The total Veil Complex with an angular diameter of more than 3 degrees is still a bit larger than what I have captured here in my 150' by 186' FOV.

I processed and stretched the 3 narrowband channels separately before combining them into a composite color image. During nonlinear stretching, I strived to retain as much of the faint nebulosity in the corners and outer regions as possible. More of these faint signals are situated in the periphery of the FOV than in the center due to our edge-on-view 2D perspective of this roughly spherical 3D object.

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.
