Geminids Dust thru M42

 

I only had a small weather window earlier this month and missed the Geminids Shower. Interestingly though, on the following night, I set up to try to capture one of my favorites - M42.?I haven't processed the images taken but attached are 3 - 30 second exposures of M42 with some Geminids going thru the image. These are in sequence with about a 5 second delay between them and this must of been some of the trailing small dust particles of the main group in the upper atmosphere. Any way - pretty cool to catch them. I probably have about 30 similar images out of about 100 and can't use them in the image stacking for processing,?both disappointing and cool!

Tom,

They are most likely satellite trails.

To me, those look more like satellites then Geminids.? Many go through that region of the sky.

I would say Satellites, too.
Reason being, I've capture the same thing about 5-6 years back. If I remember right, there are 5 that cross The Great Orion Nebula.
Unfortunately, it's going to get worse and worse as we fill the sky with space junk.

Hmmmm starlink

Worst thing ever....should be banned. but oh noes, there's money to be made.

Well, in about 30 frames, there are almost 100 trails and none on the following night and none a week later. I guess they could be satellites but I'm still leaning the other way.
 

Yeah i'd say satellites as well.?

meteors have a different signature (the have a bulge in the middle) and they are so fast they aren't usually visible across frames

I think it's probably starlink, since most other satellites are individual

Still, it's very cool even if it ruined your M42 :)

OK... But try not to fall down, Tom. ;^)

You may be able to plug in the time and date to skysafari and see if satalites show up.?

Great idea, Jamie!

I'm convinced!!!! Also after thinking about it more - if these were really particles - then why didn't they just burn up!
Thanks guys

Depends on your latitude (to get a boatload of geosats thru the Orion Nebula)

?

Parallax and “The Clark Belt” is a nasty combination..

?

But they are easy enough – mostly – to remove in processing.. Sigma Rejection, I think.. Just google “removing satellite trails in astrophotography”..

Even more fun is the few days when the Sun is at the same declination, and the most every satellite in the Clark Belt flares.. Many can be seen naked eye..

?

You’ll remember this when you happen upon a blinking light in the sky that blinks every 30s to 2min or so..

?

At 38 North, this happens when the Sun is about Declination -5 degrees.. or thereabouts.. (I haven’t done satellites in a long time..)

About 7 years ago I saw a star-sized light moving very slowly thru Cassaeopia. Very slowly.? Took a minute or two to move thru one of the Vs in the W. It did blink off once for a few seconds then back on. And then it did something very strange. It stopped. For maybe 15 seconds.? Then it began moving again. But at a right angle to it's former direction. Moved away at same slow speed directly North. Out of sight after min or two. Never seen a UFO AFAIK but this thing moved in a way that goes against everything I think I know about physics of space movement. This was not a satelite.? I've seen plenty of them.? Still very curious about what this may have been.

I know, Tom, I was duped, too.
Only I was sure it was an Alien Space Force.

Happy New Year!

Those are geosynchronous satellites, which would appear stationary from the ground. Since you are tracking the sky, they appear?as short, parallel line segments. I get them most often while imaging M42 from my location at 38 degrees north. If you like, you can confirm they are exactly the same length as the stars would have trailed if your tracking had been turned off for the duration of the exposure. In fact, you can do just that, and the stars will trail while the geosynchronous satellites will appear as stellar-like points on the image.
