Flower-shaped starshade might help detect Earth-like planets
"that allows a telescope to photograph planets from 50,000 kilometers away"
The Grammar Nazi emailed me and said that although he understands what you were trying to say, you got it wrong.

Moon Saturn Occultation - 22 Feb 2014
Saturn has some of the highest contrast details of any planet, it really gives an effect of being a cutout or sticker. This is a very common reaction from public viewings on Saturn. People will look for stickers on the other end of the telescope. I have used some really high end refractors where Saturn color is subtle, can look almost paper white and pastels, etched with details.
The first time I looked at Saturn through a telescope I was struck by the fact that at this magnitude it looks like an icon of Saturn cut out of paper, not the actual Saturn.
Moon Saturn Occultation - 22 Feb 2014
From the vimeo comments: "The telescope is 2000 mm, but you need to add the 3x crop. Video at 1:1 pixel is the best way to shoot the moon/planets."

awesome!!! I had a tour of the Subaru Telescope in Hawaii this past Summer and these things are just huge and amazing. Very similar scope.

Why The Full Moon is Better in Winter - MinutePhysics
Winter (and its full moon) also means that you cant watch stars or planets nearly as well, since the light of the moon is interfering a lot. Also the cold weather is bad for telescope mirrors because they will fog up or even freeze over.
Not to mention that I like winter because its so dark and making siting at home very cozy. Having a full moon all night long destroys that feeling.
The Solar System -- our home in space
I have seen one of the tiny moons of Mars (Deimos) from my front deck through a 7" refractor telescope. That moon is 9 miles wide and I saw it when it was about 47,000,000 miles away.

What Canon did you buy? I recently sold off a bunch of telescope stuff and beefed up a Canon kit.
Neil deGrasse Tyson: We Live in a Cosmic Shooting Gallery
Not according to David Thompson, a NASA astrophysicist and deputy project director on the Fermi Gamma-ray Space Telescope who compares the risk to Earth from a future gamma-ray burst to "the danger I might face if I found a polar bear in my closet in Bowie, Maryland. It could happen, but it is so unlikely that it is not worth worrying about."
There's a greater chance that one (or more) of the stars within about 6000 light years or so could give off a gamma ray burst that would wipe out any life in the solar system, no matter where we hid it. It's been postulated the previous-to-the-Yucatan-asteroid large scale die-offs could have happened due to GRB.
