Object Moving Through M42 new
      #5583509 - 12/22/12 01:51 AM

I was taking photos of M42 tonight. I'm pretty new and didn't get anything I would sat is usable. However, when I was looking through my shots I noticed something moving through 4 of my frames. The first two are 15 second exposures and the second two are 29 seconds. I blew out the brightness and contrast and drew an arrow to what I saw.

What could it be?

If it were moving rather slowly west to east, it may be a geostationary satellite. You can tell by shutting off your clock drive. If the object remains stationary in the field, you will have seen one of the satellites we rely on for communication or weather imaging. The band of geostationary satellites goes right through where M42 passes, so such sightings are not unusual. Clear skies to you.

Thanks, David! Satellite was the first thing that popped into my head, but I don't know much about these things.

Geostationary satellites show up in a lot of M-42 images.
They can get annoying.
Your question is not uncommon, especially for this time of the year.

Good catch. Your images are orientated with north = up /east = left and your satellite is moving approx north/south so is probably a lowish earth orbit polar satellite. Geosat, due to their great distance, move more slowly right to left

Good thing I didn't mention it to the wife last night. She would have thought Mayan end of the world for sure.

Thanks, Jake! I'm just getting started and hope to get much better in the future.

It was an alien spacecraft. They're going to land soon. Aaagh!
