Metallic UAP or Balloon

Hello NUFORC,
At around noon on 11/18/2023 I heard two low-flying fighters outside of our house. As I was standing in our backyard, I saw two F-35's fly around the house three times over the course of 15-30 minutes. I don't know why there were F-35's here, but Davis-monthan AFB in Tucson is not a fighter base (I was stationed there from 2007-2011). I don't want to assume too much, but the nearest F-35's I know about are stationed at Luke AFB in PHX. Sometimes they will have an airshow or other host nation partners' pilots will train here with some of the U.S. pilots. Either way, when I heard the aircraft outside it prompted me to investigate.
As I was observing them I witnessed two other high-flying jets (higher than 20k ft approximately) that were streaming across the sky. This prompted me to grab my telescope (25mm lens) so I could get a better look at them. As I followed one of them with my telescope I observed a UAP floating in the background (not following the aircraft, but caught my eye). Light reflected off of it like it was metallic. I continued to observe the object for approximately twenty minutes until inclement weather prevented me from observing it anymore. It was moving, but it was very slow. I know because I had to adjust me telescope every minute or so. The photos that I took are through my 25mm lens facing west by southwest of our backyard. Even when light wasn't reflecting off of it, it was hard to make out what it was (that's how far it was).
I don't want to assume what it was, but I attached some photos that I took from my telescope. It is difficult to take photos with my phone through the lens, but the photos do reflect what I saw.
Please feel free to contact me if you have questions or concerns. If you call please leave a voicemail so I know.
Respectfully,
Scott
