Astrophotography with GPS O-1 !

OK, i guess this is the key to getting a result like that you got .....

But how do you adjust the field?

And if I may, a second question: how much time passes between shooting and shooting? Do not move the object between each shot (and more with 200mm focal length)?

I can not understand how the dog track sensor movement entre without the stars shooting and shooting.

Would I be happy if you could explain it to me, because i have a K5 and O- GPS 1, but i can not understand how to do what you have said to each shot without the stars come out in a different position every time.

Please, i am very interested in. This, and i really appreciate it if you could explain me in detail.

As you can see, i must be a little short of mind. Please let me apologize for it.

But I think the key is just how to make shots with the stars different in the same position, having spent some time between shooting and shooting and a shift in the therefore visual field, considering the camera follows that in a fixed position (initial) and the sensor returns to the home position for each 'shot ..

Do not understand how to restore the visual field so that the stars are exactly the same position as in the previous shot and I think that is the key.

I await your response with great interest.

Forgive my way of expressing myself, but i don't speak these language right enough.

By the way, I forgot the most important, the pictures are impressive, especially the second.
The third, was made also with the O-1 GPS?

Thank you very much and best regards.
