I have seen several photos of the our milky way galaxy, other galaxies and some photos of even 100's of galaxies in the same picture. How do they do it? Usually if you see in the sky, all you see is the stars. (naked eyes) I believe to be able to see actual of our milky way galaxy we need to be very very far from it; but we are part of it. How can we see it even with the best telescopes? I have read there are highly sophisticated telescopes that watches the space for quite a long time to get a picture of 100s of galaxies but would like some detailes explanation on how is it done?
