You mentioned that this was 12 5-minute exposures stacked, however I can't understand why there's no motion blur.

I am using an equatorial mount, that compensates for the rotoation of the Earth.

The easiest way to start is with a tracking plattform. With a telescope you need a heavy equatorial mount and for perfectly round stars also an autoguide system.

To learn more I suggest getting a book, since a book will give you all the information needed. Also search the web for details.
