    Default Anyone into astronomy?

    I found some pics I took a couple years ago through my telescope--thought I'd put them up.

    Each image is actually a composite of three seperate CCD photographs taken through red, blue, and green filters then merged. Exposure time through each filter was 20 minutes to 45 minutes. To compensate for the earth's rotation which would produce streaks from each point of light, the scope has to be aligned as precisely as possible with celestial north, then guided by placing a star between a set of crosshairs and keeping it there using the scope's movement buttons for the duration of the exposure. This can be a serious pain..... We don't have the dark skies you really need to get the best images out here, but I was pretty proud of these.

    The first one is M27 (or the Dumbbell Nebula because of its shape) in the constellation Vulpecula. It's speculated that this is what will happen to our own sun in about another 5 billion years. Object is about 1200 light years away.

    The second is the Eagle Nebula, M16, where gas and dust are combining to form new stars. This nebula is about 7000 light years away.

    The last is the Swan or Omega Nebula, M17, another star-forming region about 5000 light years away near the constellation Sagittarius.

    Anyway, one of my hobbies I wish I had more time to spend doing.... Enjoy!

    Here are some links to the same images taken with the Hubble Space Telescope. These never cease to just amaze me.....

    Here's another of the Swan taken by pro astronomers from earth:

    Yup, I love that stuff. You really can get lost in those pictures.

    I grew up in a small town where we could actually go outside at night and see billions of stars. I miss that. Haven't seen the night sky in a long time.

    Those are so cool! I find those pictures to be very interesting. Great pictures!

    I live in the city so it's always too bright to see much up there. Oh well. Astronomy is so exciting!

    Thanks, you guys!

    Just knowing that the light we're seeing now from some of those objects left there almost at the dawn of human civilization and is just arriving, that's pretty humbling to me. Kinda puts everything petty and trite into a very different perspective....

    Awesome pics, Louis!

    I studied electron microscopy in college, and loved astronomy because it was based on all the same principles, but at the opposite end of the wavelength spectrum.

    I'll have to see if I can dig up any of my old photos of retinal cells...

    Very cool photos, the technique to get them must be fascinating by itself, let alone the complexity of the subject matter.

    And I wonder how you can say you don't have the patience for slow-growing paphs when you can wait 45 minutes for a single exposure for a 3-exposure picture??
