Here is the last of the images I made on my inaugural night sky photo trip. I am not personally happy with the composition. I wish the smaller Trifid Nebula was not so close to the frame edge. Otherwise very surprised at how the image turned out.

Specific Feedback Requested

Is there any vignetting in this image, based on your experience with deep sky images?

You have no vignetting in this so maybe it was not the issue with the other one.
You got some color in this one also.
DSLR lens give you a lot of stars, way too many, filters help cut back on them but they are a processing problem in all Astro photography.
Most take the stars out and process the image without and add them back in.
That way they don’t get stretched as much.
