One Last Jupiter
I added a picture of Jupiter's Europa's shadow on Jupiter's cloud tops to the Jupiter's moons' page entitled "Jupiter's
moons" (I don't think I've written a sentence quite like that before - Dad may have a suggestion or two for me).
Finally got a chance to go outside with the telescope. As most know, we live in the Houston area and battled through
hurricane Ike. Lots of work to do at work and around the home so a little time for my hobby tonight.

Uranus Added to Home Page
I stayed up late last night so that I could get some images of Uranus near opposition. The seeing seemed a little
better than the forecast so I took advantage of it. It's now on the home page. On the "Beyond Saturn" page is
a picture with three of Uranus' moons. The biggest moon, Titania, is the 8th largest in the Solar System. So,
they are all pretty small and the least as a percentage of mass of their parent planet.
I also imaged Triton (Neptune's largest moon) and replaced the old image I had of Triton on the "Beyond Saturn" page.
It's a lum only shot because it's too small to see any color.

Neptune is receding, Uranus is next!
Jupiter is at it's highest point in the sky at around 9 pm now. I added a new pic from recent nights to both of
the Jupiter pages. Neptune reaches its highest point around 11:30 or so. Uranus is even later. I
haven't stayed up that late to get a better picture of Uranus. The weather finally broke a little this weekend.
It's been hot and muggy with lots of skeeters so that tends to curtail my nights a bit. The tropics have been very active
too which have limited the number of nights that even have decent skies. This weekend it's been less muggy with drier
air - of course the skeeters are still around but not as bad.
So those are my excuses. I do have a new Neptune pic on the home page. I moved the old picture to the "Beyond
Saturn" page. I'm hoping to Uranus with a few of Uranus' moons soon. Uranus will be easier than Neptune but
the moons will be challenging I think.

| Combined two images. Neptune taken at f29 and Triton, its largest moon, at f10 (then enlarged). |
| It's getting farther, week from closest pass, f/29 |

| RGB image of Saturn on 3/16, good seeing but fog was rolling in, storms visible |
| It's getting closer, Venus URGB, f10, 3/5/09 |

| Can see crescent with binos easily, try with naked eye to test your vision |
| Mercury is always around - RGB 200% f/29 10/21/08 |
|
|
| But usually is too close to Sun - it was about 15 deg from horizon in morning (east) - poor seeing |
| It's getting farther, Uranus RGB 9/6/08, 200% f29 |
|
|
| Same image scale as Neptune. A lot of green when imaging, less blue but boosted blue. 6th from Sun |
| Near Mars' closest distance to Earth for 2007 |

This is an LRGB photo of Mars made on 12/21/07 05:52 GMT. It's centered near Eden but Syrtis Major is still
visible. I have an 11" SCT and used a monochrome Imaging Source USB 60 fps camera at f/25. I used Registax,
Photoshop and Maxim DL during processing. Thanks for visiting!
