Beautiful tracking of your equatorial platform. It also appears that streaming of the comets tail can be seen here over the four hour period that you recorded. This is the first time that I have ever seen actual live motion of a comets tail streaming ion gas and/or dust. *I was always curious as to where astronomers get the tracking program to accurately track the comet. Can you inform us? If so, thank you.

Your documentation is rare and much appreciated!

Congrats on your fine work!

Excellent!
I have also tried this method, but bad tracking will result in time-consuming and complicated editing to produce a similar video.

Tell us about your tracking method?

You may have a misunderstanding with my poor equator. This was made from only 18 images per 15 minutes. I only adjust each nucleus position by Photoshop after shooting. Unfortunately, I must go to Shanghai@China on business for two weeks from now on.
