Spaghetti Nebula & Mars (569 hrs)

More on Instagram: @jeffreyhorne

I took this image from my backyard in Nashville, TN (bortle 8-9) over the course of the last three winters, with a total of 569 hours (3.4 weeks) of exposure captured over 147 nights.

I was so lucky that Mars entered the frame in 2023, and you can see Mars on the bottom left of the image.
