    I always wondered what these lasers were for, thanks! They are certainly very cool :D the whole "noise canceling" of the atmospheric distortion is ingenious! It's like headphones for space.

    Long story short: *It's like your headphone's ANC (active noise cancellation) but with light.*

    I thought those lasers are used as a finder scope or something before watching this video. Thank you so much for this video. Also those coronagraphs sounds awesome. Can you make a video about them?

      Thanks! :) I'll add chronographs to the list if topics, but I touch on them briefly in my video on the Nancy Grace Roman Space Telescope!

      Nancy Grace Roman Space Telescope video was the video I heard about them :)

    I have a 7.5 watt blue spectrum(brightness) laser that I was wondering if it would punch a hole in the atmosphere to improve my telescope photography. Would this work and do I need prior FAA permission to use it?

    Heyy amazing video. I had a question.
    I saw the photos of the laniakea super luster the other day. But I couldn't fig out how we know the shape of the supercluster even though we haven't seen it from a 3rd person view.
    Could you please make a video on that?

    I had the mirrors on my Newtonian re-aluminized to 96-97% reflectivity and the primary parabolic mirror refigured to near perfect focus, Strehl ratio is perfect at 1.000, an impossible objective, but mine was taken to .986 ratio with a .08 wave or 1/12th. So my 150mm (6") mirror gets collimated (lined up) with a laser to dead on every time I setup, I usually don't have to adjust, but I make certain my telescope has reached equilibrium with the outside temperature or I can get heat differential distortion like heat waves on hot pavement.
    I pay attention to Stratosphere's weather as well as our local weather. Wind causes distortion as well as other things like thin layers of ice crystals can form at the borders of the two zones, high up moisture that you see as a ring of haze around the Sun or Moon. It helps to know what is going on up there. Most of stargazing is done pointed near zenith as there is less atmosphere to see through. Although some observing is done low to the horizon like for Mercury and Venus. Also in the lower Northern latitudes some objects like the Omega Centauri or Caldwell 80 only climbs to around ten degrees above the Southern horizon from the desert Southwest. There is the C77 galaxy with its shooting radio jets.

    No you can't see that with a telescope on Earth. Here is a photo taken by an amateur with a 9.25 inch telescope with a lot of exposure time.

      That's incredible. It's amazing to me how people can be so educated like this. I'm nowhere near that smart, and yet people tell me that I'M the smart one.. If only they knew..
      Regardless, very very cool!

    Definitely very cool, Chris! A brilliant solution to an optical problem which will make earth bound astronomical observations much clearer, and with the possibility of giving resolutions, thanks to adaptive optics, far better than those achieved by Hubble and the JWST when viewing certain objects

    • @ChrisPattisonCosmo
      @ChrisPattisonCosmo  2 года назад

      Absolutely, it's an incredible solution and the engineering to make it happen is even more impressive!

    The lasers bounce off the firmament, or the glass ceiling just like Hilary Clinton would call it. There used to be short compilations on you tube but now they are not.

    Still no clear workings of laser sending and receiving Telescopes, hitting a 1x3 foot Retroreflector on Moon and getting a perfect return.

    Yes its partially what they are telling you for sure but large lasers cost a lot of money on their electric bill. They couldn't afford to take those pretty pictures without military funding. Its a Win,Win !

      Have you ever checked out Vibes of Cosmos channel?
      SUPER fascinating plasma moon research and experimentation on a whole other upgraded form of steroids...
      MAN...
      Start with "map clock and seasons"
      I'm assuming you're open minded and have an affinity for well documented independent or alternative research...
      Either way, cool 10 minute mind fk...
      If you wanna see how far the rabbit hole goes after that he's got the breakdown labeled as documentary seasons. Obviously start at the beginning.

      how did you go from "busted the laser" then to "space is fake"

    • @dogteam6178
      @dogteam6178 День назад

      How does this have to do with space being fake? You can’t see the laser anymore means it’s fake?
