Due to my very small FOV (1/3 chip @ 2000mm FL), I rarely catch one of those priced moments.

It finally happened last night. One of the 3260s Ha band exposures captured I think a plane going by? I am no expert but was it too narrow to be a plane's taillight?

Needless to say I am keeping it in one of my trophy folders, even though most of you have a lot more spectacular show of trails.

Any collectors out there?

One thing that's always interesting is to stack your lights using a maximum combination. It's fun to see meteors, planes, asteroids, satellites, lightning bugs, cosmic rays, or UFOs.

The other one that is even crazier to see is when you get weird reflections that almost never appear.  Here is one of a super bright star just out of the field of view bouncing off the pick off prism of the oag.  Never saw it before or since.  This one was brutal to process out.   :)

For me waiting for another trail to stack, may turn out more difficult than bringing out the M57 halos.😆 This is just a single light calibrated by single dark.

I thought since they are "outliers" would they not be removed after stacking?

Large FOV, plane with lots of interesting detail....

I grabbed over 200x 60s subs of NGC7331 and friends in the same night. Only one of them looked like this. There are multiple events here, maybe over a dozen.  Few are parallel, and the paths are not all straight. Best guess is I caught the debris trail of a large meteor we saw disintegrate dramatically.

This was taken 6 years ago with CPC0800 mounted on Mitty wedge at 2000mm focal length, SXVR-M25C OSC camera. 10 minutes sub-exposure. A jumbo jet flew by over my house on the way to land at the airport.

Looks like the mount went to home position during the end of the exposure.

So far is it right to say plane trails are usually perfectly straight lines in parallel, or at least no wobbling along the path? Seem to make sense if it wobbles, we either have a drunken pilot or a plane with mechanical difficulties.

Meteor trails on the other hand appear to wobble a little in its path. So I have likely caught a meteor, not a plane?

If so the star trails would have the same spacing, not crossing one another?

Nope. The mount was west of the meridian and ran that way until I shut down.

Probably an airplane strobe. I've seen some good ones.

Or a tumbling satellite, I'd assume an airplane would have 3 lights

Here are links to a couple of mine.  A meteor in M-33 and a planned Iridium Flare in Orion.

Orion  https://flic.kr/p/6kMV9x

 

Both are pretty cool.

The very first frame of the night (satellite):

Three frames later (airplane landing):

I got several more satellite trails later in the same night. Wasn't a good night for me. :fingertap:

That's a 10 minute exposure, if it were a plane it would be a solid line. Whatever it is, it's moving very slowly, probably tumbling.

What does it mean when satellite is tumbling? Was it out of control?

BTW with additional samples provided, I think more likely I caught a satellite, not a meteor.

Now if our cameras have global positioning and time stamps on record (an approximate should be available to us already), some of those trails could be traced and identified would they not?

Here's a fun one from a few months back. I had just finished setting up and was doing a quick test shot to see if the flame/horsehead were in the frame correctly. Instead i caught a plane going through one way and the beautifully bright Space Station searing through the middle :) It was pretty great to see in person and on the camera.

I guess this counts.  While capturing frames for a star-trails image, I happen to catch an Iridium Flare.  I've caught them before & since, but was trying then.

Yours looked very difficult to remove.

My single satellite trail could not be removed after stacking 5 frames, but after I added it to a much larger stack, the trail was gone, with just some hint of noise left at the lower part of the image, and that was after the image was fully stretched.

That is definitely a tumbling body (like rocket debris) or rotating satellite.

You can identify asteroids and satellites pretty easily with most planetarium software, lat and long, and a timestamp.
