Mars Images-1999-2001 |
Mars can be
a great object for amateur scopes, but only when it passes close to the
Earth (Apparitions). These close approach times occur on average
every 780 days. The last close approach was 2 May 1999 and the next
one will be 25 Jun 2001. The next three apparitions will be
very good, so get ready.

This was my best image of Mars during the 1998-1999 Apparition. My LX 200 and MX-5C arrived in Jun 1999, so I missed the best imaging opportunities. Just wait til next time! | Focal Ratio: f20 |
Exposure: 0.4 Sec | |

This is my first image of Mars in 2001. It was really just a centering image before I switched to the f30 optical configuration, but it shows what Mars might look like in a 6"-8" scope at 100-150 power. Yep--pretty small. |

Well, I think it is Demos. I've retouched the image in Photoshop to remove the glare from Mars. The object I've marked as Demos is in about the right place. Click here for an un-retouched image and explanation why I think it is Demos. |

This was my primary image of the 24 May imagining session. I took about 200 images. This is an average of three of the best taken during a moment of relative good seeing. Mars is low in the southern sky for Northern Observers during this apparition, so it is difficult to get a sharp image. Central Meridian is about 80 degrees. Mars appears to be about 1/2 the size of Jupiter in this image. Click here for a short animation. |

The orientation in this image closely matches the Meridian screen capture below. The central meridian is about 300 degrees. Click here for an animation. |

This is a screen capture from the freeware Program Meridian. It shows how the planet Mars should look when the central meridian is 300 degrees. This will put the surface feature, Syrtis Major, just to the right of the center of the planet as seen from Earth. Click here for a list of dates and times during the 2001 Apparition when the central meridian will be 300 degrees. |
The central meridian for this image is about seven degrees. |
