    I never heard of Edward Barnard, nor his star. This was highly educational and thank you for sharing.

    Hi Paul
    Since 2008 I make a picture from Barnard's star every two year in early september.
    I use my trusty old Orion ED80 and DSLR for imaging Barnard's star.
    When you combine all these images you get a nice impression of Barnard's star's own movement in relation of the surrounding stars.
    Thanks for another very interesting video.

    Nice video. I've read that with modern astrometry, a long focal length, large aperature, and great seeing that you can measure Barnard's star's proper motion in one day. I have been unable to measure it in a month with a 4" Petzval but my second image was taken under very poor seeing. I'll try again when I return from vacation in two weeks. Have you been able to see its proper motion?

      Hi Mark, thanks for your comments. I have not tried to make any measurements on Barnard`s star. But now that you mention it, it might be interesting to take a series of photos over time just to compare it (the distance) to nearby stars on astrophotographs..... I am not technical enough to know how to calculate "proper motion". Thanks for watching Astrophotography Japan! PAUL
