Noisy, cleaned and trimmed in Lightroom 5. Canon EOS 5D Mk II at ISO 3200, 8-second, singlr exposure.
I found it interesting that there are 4 streaks from something in this shot. Not sure if its meteors but pretty sure its not 4 satellites.

Yes they are satellites, geostationary satellites to be exact. From the grouping they might be DirecTV 10, DirecTV 12, Spaceway 1, and SES 3.
If you can send me your exact longitude, latitude, elevation and the exact date and time to the nearest 5 seconds, I might be able to find a positive match for you. Or, if you prefer you can go to CalSky web site and see if you can put in the parameters and get an ID on them. Neat photo, I like it.
One other thing, try turning your image into a negative B&W, then boost the contrast as much as you dare. See if there is a much fainter satellite trail just below the one on the extreme right. If there is then this could be AMC-1 (GE-1), which would make the overall identity correct.

Thank you. I cannot pull a 5th trail out of the murk. Here is a shot that would be roughly 41 seconds later. I am not correcting for shooting with an SCT so the image is inverse of normal.
This was shot at 10:21:40 MST 35.15 -106.58

I took the liberty of stretching your photo to see if there was a 5th satellite. In your later image there was one indeed, very faint and I have marked it as number 5. The pattern is no longer there but that still does not rule it out as it being the satellites I suggested. Also I have posted a photo I took last summer with the satellites. The interesting thing about these satellites is that if you point your telescope at the same declination as the Orion Nebula, turn your drive off and take an exposure (longer if possible), the stars will trail but the satellites will come out as nice round dots. You may have to take several shots to find them as they will not be moving across the field. They are in an arc completely across the sky at roughly the same declination as M-42 as seen from your location and there are about 70 or 80 of them, lol. Have fun.

I was looking for number 5 to the side not in the lead. Thank you for all of the information. I love learning all this new stuff. ;)
