Yes, that 's quite fast !!

But an experienced observer using a dobsonian scope can easily observe 12 CV with 7 minutes.
That's no problem if you know the star fields from thousands of previous observations.
Of course it helps if the stars are in the same part of the sky.

I guess observers like Gary Poyner and Gene Hanson often make observations that fast.
I did the same when I observed visually using my 13.1 inch dobsonian.
