I've been recording video of the sky for years, using several different types of cameras.
Which include, digital night vision, full frame ccd, smaller ccd cameras, cmos cameras
cctv cameras and using various different lens setups ranging from
14mm to 300mm focal length of various f stops.
One thing that always surprises me is that I'll always record these "flashes" of various colours and shapes.
They only occur in a few frames or for a split second.
I used to think they were just "hot pixels" getting a bit excited over maybe a bit of extra electricity
or a bit of extra light from somewhere I don't see with my eyes.
But then wondered why no one else was complaining about it their videos.
That is, if it was a camera fault or ccd chip fault.
I also own the Sony a7s and it produces some red or blue hot pixels when recording in a dark sky with high iso
settings. But these hot pixels are very small dots compared to the unusual flashes I see now and then.
Here is one of the first flashes I recorded using a digital night vision monocular
which records to its own flash mem card, the Lunar Optics LN-DM50 HRSD
I recorded many more after that and thought it was the nv device.
So as you can see it was getting ridiculous as to how many this camera was recording.
After accidently killing this nv device I decided to get the Sony a7s
which is perfect for night time recording.
But it too recorded these flashes,
So I was coming to the realization that it wasn't the cameras fault.
Then on new years eve I set up a ZWO asi 120 astro camera up with a wide angle lens to record the fireworks
and got these,
Some one told me they were cosmic rays.
The ones from new years eve could have been. They were grouped together, and kind of splayed out as they supposedly entered the atmosphere.
But the others don't fit the same description.
I eventually gave up wondering about them. I had no answers nor did anyone else.
No point asking astronomy type people. They won't admit to ufos anyway. Whether they
believe or not. They'd lose their money for their projects if the gov thought they were
So I stopped editing flashes after that, even if I saw them.
But eventually I caught two similar individual flashes on the same night in different
parts of the sky. With the a7s camera while recording an electrical storm.
So I just had to edit them into a video for reference later. (just in case)
I still think these are not hot pixels.
I'd like to hear anyone elses opinion on these, or any videos you have to compare to.
I definitely think these are not cosmic rays.
