Man that is awesome. I wish I could take pictures like that, but first I need to get a telescope, then I need to get a decent camera for shooting this type of shot, then I need to... Wait I need money. Guess it will have to wait, but great shots anyway. I really love shots of the moon, never really see to many of other planets that is pretty awesome as well.
Did you know in August they say that Mars will be so close to us that we will be able to see it with naked eye. I read one email that stated that it will be about the same size as the full moon. That will be awesome.

Great shots strangehost!
On the first one, what software are you using to do the image stacking? Also, did you delete all of the backgound stars? I don't think I've ever seen a stacked planetary image without a gazillion stars in it..

That sounds more like publicity for Tom Cruise's new movie.
Mars is about 150 times as far away as the Moon. You can always "see" Mars with the naked eye, just not as a disk. |

Jeremy: GeneralE is right, Mars is always a naked eye object, provided you know where and when to look. Most of the time it looks like a faint-ish reddish star. About every two years, when Earth overtakes mars in their respective orbits, Mars gets much brighter, but still looks like a reddish star. That will happen again this October.
Emanuel: No stars bright enough close to Jupiter to be included in this image or they'd show up. The stacking software I use is Keith's Image Stacker for Mac OSX. There are about a million Windows packages that do the same thing. Google astrophotography image processing.

Great astrophotos John! I almost hauled the Celestron outside last night, too.
As others have said, Mars is always visible to the naked eye unless its over the horizon or lost in the glare of the sun, but no planet will ever appear anywhere near as large as the moon. The entire view of Jupiter shown below (including its moons) is probably around the same size as the full moon (maybe smaller). The odds of having even a single naked-eye star appear in that image area are something like 1 in 30. |

Shannon is right, the odds against having a bright star close enough to a planet to be in the same telescopic view is very slim. There actually were a few stars close to Jupiter last night, but the brightest one was 9th magnitude (the moons are about 4th magnitude, MUCH brighter than any close-by star.
This view was generated by Starry Night Pro for the approximate time of my photo last night. Note the moons to the left. The two objects below and one above the planet are background stars that just happen to lie along the line of sight. |
