Veil Nebula Mosaic

I finally got a couple clear nights with the chance to image the Veil Nebula / Cygnus Loop and try my first mosaic image capture consisting of two panels. This is the first time I've had a serious opportunity to try the Veil region. The field of view is just a little bit too large for my setup, and I decided I wanted to get the whole structure into one image. Fortunately, two clear nights in a row gave me a chance to try something new. Astro Pixel Processor did a great job merging the two panels together - I cannot even tell where the overlap is.

As I was processing, I was also trying to decide which orientation I like; each way I rotate it, it looks like something different to me. I finally decided I liked it this way the best. I found the stars a bit distracting, so I did some star reduction to make the fine structure of the nebula more dominant. I'm uploading a starless version also since there's so much structure to look at.

Finally, I am still really liking the Antlia filter - I see no halo on 52 Cygni at all! I think my L-Extreme is now officially retired. The moon was mostly full (~90% I think) and up in the sky during the whole capture, so background noise is even higher than my usual, but the filter cut most of it out.

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.
