very good I too am interested in Astronomy(got a D in a collage class. I guess I loved the subject,but not all the complex tests. what latitude do you live in? if your listing constellations such as Ursa Major,Draco,and Perseus then you must be living north of at least 20 degrees north latitude. I live at about 35 degrees north latitude in the central coast of Callyfornya(thats how Governor Arnold says it.)
spain is in between 35o north and 40o north latitude so your pretty much seeing the same constellations I do. Can you see Orion? If so you are looking at the border of the northern and southern hemispheres.during the winter months(like right now) we see mostly the northern hemisphere with Orion and the tops of a few southern hemisphere constellations sticking out above the horizon. then in the summer the earth tilts towards the southern hemisphere so that more constellations in that region can be seen. A good tool for stargazers is the Miller Planisphere. look it up and you'll find a few sites that sell them. owning one is a must for any astronomer. oh and your welcome.
Me alegra que hayas elegido este tema (si es que os dejaban elegir xD), me encanta la astronomía! Dentro de poco espero comprarme un buen telescopio ^0^ Ya no se me escapará ninguna estrella del cielo nocturno >:3
Muy original la forma de mostrar las constelaciones ^^
