On the question of this being a sighting of a geostationary satellite, the answer would be a resounding no. Reported near Deneb, this places it around 40 degrees north of the celestial equator, so it could not be in geostationary orbit. Some GPS satellites travel in inclined orbits that might position them such that they could be seen in this region of the sky when approaching the extreme northern boundary of their orbits, but not else-where and they certainly wouldn't be stationary in any case. Nor would one anticipate them to be rolling with a 7-second per revolution rate. An estimated magnitude here might likely have been key to better IDing the object's nature and altitude, but sadly not even a rough guesstimate of that is available.

Personally, I'd just forget about this and move on as narrowing in any further on the object's actual nature is essentially hopeless.

I had a similar occurrence. On August 5th at 1am, my son, our friend, and I went fishing on Lake Arrowhead and when the bite slowed, I began pointing out various asterisms, etc. Near Cassiopeia, we spotted a bright flash with a period of about nine seconds. There were no other lights (nav or otherwise) and it was moving much slower than an airplane anyway. After about 90 seconds, the flash stopped.

We moved the boat and they began searching Cassiopeia again and the flash was back- but now with about a four second period. Again, it stopped and we moved once more. The bite slowed and we three were staring at Cassiopeia hoping to again spot what we took for a satellite.  A dim star brightened suddenly to about twice the magnitude of Sirius and then disappeared completely! I've never seen the like in over 60 years of star gazing and have no idea what it was that stunned us that night.

As BrooksObs said, "Personally, I'd just forget about this and move on as narrowing in any further on the object's actual nature is essentially hopeless." and that's what we did.

There's a lot more space junk up there than before.

We have a UFO here, we can't identify it, the U in UFO...
A geostationary sattelite would probably be moving slower, and in general don't pulse. Tumbling sattelites have a more subtle pulse, which is also at regular periods.
What is being described here is some sort of tiny aircraft or high altitude spacecraft, and should probably be reported to both official NASA/air force and UFO channels.
This is very interesting. Skeptics will be skeptical for skepticism's sake.
I am more open minded, I used to be an "open minded skeptic", but then I had some experiences which made me no longer a skeptic.

WRONG.
Satellites, rocket-boosters, etc. tumbling or spinning or out-of-control, slowly changing orientation, etc behavior could exhibit a large range of flashing/flaring/pulsing behavior.
No need to jump to UFO conclusions because you incorrectly assume things.

I pulled out my little used 10 inch dob last night on a whim. I did not even put my Telrad on since I was just planning to scan the sky for a little while. I pointed it to near vertical since at that position the eyepieces is about at eye level and the Milky Way was visible overhead. Before I even focused I saw a pulse of light, then 7 seconds later, another (now in focus) and it continued for the entire 40 minutes I was out.

It did not appear to be moving, at first. Every few minutes I'd have to nudge the scope to get it centered again. At one point I went into the house to get binoculars an another time to get my tablet with Stellarium, and the object was still visible when I returned. As my eyes adjusted to the dark I could see that the object was moving, extremely slowly, against the faint background stars.

It's location was just below a line from Vega to Deneb, toward the Deneb end. I put it at 80 to 85 degrees azimuth in the northwest sky around 9 to 9:30 EDT. My location is at 42 north.

I'm guessing a revolving satellite but that is just a guess.

With all the wild speculation on here,
did anyone happen to check if there were any satellite candidates in the area?
The OP was using a large Dob, yes?
Looks like a quick check of Stellarium without much effort pulls at least one Molniya candidate and also the Chandra X-Ray Observatory in that area moving slowly.
Regardless of what is was,
and eliminating balloons, UFOs, secret planes, Geostationary satellites that would be along the equator,

A satellite in a wide elliptical Molniya orbit should at least be a guess by someone on here.

Here's a video example of one flashing from 25,000km in my camera lens without use of a large Dob:
[note small flashing thing just to the lower right of the middle of the screen, to the upper left of the "L" asterism]
---Ironically, you can find the same "L" asterism in the demo video just 7 degrees away from Vega. Go figure.....

Thanks t_image that is what it looked like, a bit longer period and a bit brighter but that could be the camera or the scope. My camera was not able to pick it up. How would I have found that using Stellarium? It is a huge sky with lots of stuff up there.

Just curious as to how you can say 'Keiih' is "wrong" in his estimation of "Trek2000's" post? All he said was the object was unidentified. As yet, it is unidentified, unless you possess facts unknown to the rest of us? "There are more things in heaven and earth, Horatio, than are dreamt of in your philolophy...." I'm willing to bet there's a number of us nighttime gazers who have seen things which do not fit within the parameters of the explainable. Personally, I do not believe in E.T.s but I'm not ready to discount other's observations based on my personal bias.

Well, UFO doesn't draw any conclusions, hence the term even existing. Unidentified Flying Object.

A flying object, the identity of which is unknown.

This so far, fits the bill.

UFO doesn't mean alien, otherwise it would no longer be a UFO.

I have seen some drones at pretty high altitude.
