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. clear skies
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
I never heard of Edward Barnard, nor his star. This was highly educational and thank you for sharing.
Well then, this video was worth my while! Thanks for commenting and watching Astrophotography Japan! Clear skies!

Oh wow, that is a very interesting idea! Very cool!
Nice video and great story to learn more astronomy.
Glad you enjoyed it! Not many pretty pictures (I admit), but full of information. Cheers!
Very interesting, thank you
Hi Massimo - Glad you enjoyed it. Clear skies!
Awfully neat! Going to go out and photograph it tomorrow night! And, going to post it on my channel!
Great! I am glad to provide some inspiration! Thanks for watching. Clear skies!
