A quick animation of 17 JPEGS showing the motion of 8P/Tuttle across the field of the 130/780 refractor over a 48 minute period. From the Observer's Perspective.

The field of this refractor is 99x66 arcmin, so you can see how fast this object was moving. I calculate this motion to be 8.7 arcsec/minute or 7.0 arcmin over the 48 minute span.
