I photographed Mars through my 8-inch dobsonian telescope using a hand-held Canon A-40. It's posted at the spaceweather.com photo site:
http://spaceweather.com/submissions/large_..._1259931452.jpg The north polar cap (and its cloud cover?) are visible. The cap really stands out when observing by eye. The entire planet is so bright that the views had more detail as the morning twilight increased. Check it out now, as the cap will decrease during the month. |

For a sufficiently large FOV you can fit even more in

For a sufficiently large FOV you can fit even more in Now I have a minute to add some details to my previous post. The picture is a simulation of a 5 degree field from the Solar System Simulator. My camera isn't sensitive enough to get deep enough to get Neptune! We did get a quick look at Neptune early Saturday night in a couple of scopes. It wasn't hard to see, but at that time even the surrounding the stars looked a bit planetary, so it was not obvious that it was different than the surrounding stars. I could convince myself it was blueish, but it may have been light blue or we may have been just expecting it to be a different color than the surrounding stars, since I hear it's hard to see color in telescope observations of Neptune. I hope other people will try to spy Neptune as Galileo did 400 years ago! bob |

I managed to see Neptune yesterday for the first time, thanks to neighboring Jupiter. I'm not sure I would have been able to find it had it not been so close to something bright (Jupiter) since Neptune is only about 11 degrees above the horizon from where I live. It's gradually getting higher in the sky though so I know of some people who saw it for the first time this year or in the past 1-2 years.
Since Neptune was low in the sky and my scope isn't very big (15 cm) I didn't see any color. I also don't think I saw Neptune as a disk but this was difficult to tell due to Neptune's low altitude above the horizon. |

Check out Neptune in the same field as Jupiter this month! As Bob noted Galileo made a similar observation (same time of year) back in 1612-1613. http://www.nature.com/nature/journal/v287/...s/287311a0.html In reference (2) I had suggested the possibility of this type of pre-discovery observation (my 1979 Sky and Telescope article on mutual planetary occultations). I could see them still in a low power field of view in my 6" scope at 35x on Christmas Eve. I also looked at 86x. Afterwards the moon (our planetary satellite) looked very nice at a 90 degree phase angle "encounter". -------------------- Steve [ my home page and planetary maps page ]

Nice photo, though I've always liked the volcanic/smoky type of blue moon...

Nice view from here in Kendal, too...

Nice views of the red planet and those images show what amateur-astronomers can do nowadays.
Moreover, very patient amateur-astronomers with scopes equiped with CCDs have been able to confirm the transits of exo-planets (e.g. TrES-1 in constellation Lyra by Belgian Tonny Vanmunster and HD209458 in constellation Pegasus by Finland's Nyrola obs). I jus wondered if any of the UMSF amateur-astronomers are involved in any (Pro-Am) transit photometry search surveys? |

Not a telescopic observation, but a gorgeous view of Mars shining above Kendal Castle earlier this evening...

It's safe to remove the dark specs Tesheiner, that's a night-time scene - and B. W. is real.

I guess a 300mm lens could be considered a telescope.
Here are a couple of shots of the setting new moon tonight taken roughly two minutes apart, which was just enough time to run around the corner for a lower horizon as the moon dropped below my neighbor's fence. Note the irregular shape to the crescent limb caused by the cooling atmospheric layers settling down for the night. Both images 1/8 sec at f6.3, shot @ ISO 1000 -------------------- If Occam had heard my theory, things would be very different now.
