Thanks again for the encouraging comments and continued views! Makes me want to do even more of them, but they take time, preparation and patience! (And good weather)
well...wich Canon model? i have doubts, 'cause i tried to take pics of stars before on 15 seconds, and stars appears like short lines (and too much noise), because earth spins too fast (try to follow the moon with a common basic telescope in 1 minute)... now, at 3 minutes exposure time and with iso at 1600 ... i have my doubts... show me how... (and i'm from a country the world call of third world... ¬¬ )
@fabianernestopacheco Doubts? That I took the photos? They are mine - that is why I see all the focus and other imperfections! The camera is the Digital Rebel, an SLR. Not Canon's (now discontinued) model, but one which allows you to keep the shutter open longer than 30 seconds. And to reduce noise, don't use the highest ISO (1600) and make sure you take a dark frame and subtract that from the images. Also, none of these photos were taken "through" a telescope, but using lenses.
Although, to make sure there are NOT star trails, I had my camera mounted "piggyback" on a telescope, in which the mount WAS tracking the object I was photographing, counteracting the earth's rotation. I might have also been using a guide star in the eyepiece to correct for any tracking errors - I don't remember - since the effects aren't that bad at these lower magnifications. Any drift of the entire session could be corrected when assembling the animation, simply by centering the heart of M31.
Sorry it takes so long to load. I would redo it and repost it but sadly I'd lose the generous 12,061 (as of 1/14/11) views! My advice is to let it load and zip through, THEN click on the beginning of the red timeline bar and let it go through at proper speed.
if the damn clouds that has been covering the sky for almost 2 weeks now could just like.. disappear!.. i could take out my telescope and find this galaxy ! oO
Hey, I was actually thinking about this animation earlier today and trying to remember what it was called so someone could look it up. I went outside afterward and noticed Cassiopeia overhead in a clear sky.
Andromeda is the name of the constellation THROUGH WHICH we observe that galaxy from our present vantage point. The galaxy is not actually "in" the constellation, for Andromeda's stars lie within our own Milky Way, and the Andromeda Galaxy (also known as M31) lies millions of light years beyond it.
Every star we see with our naked eyes is in our own galaxy. Those stars include all the constellations, and of course Andromeda, so in that sense Andromeda IS a part of the Milky Way.
Andromeda Galaxy is NOT part of our Milky Way Galaxy, is it entirely another galaxy. It is close enough for us to see with a naked eyes. It's our neighbor galaxy, among with many others are called Local Group that contains thousand of galaxies.
A galaxy is so big that it takes thousand of light years to cross it, like Andromeda Galaxy, and the distance is millions of A.U. ( Astronomical Unit, or light years ) from planet Earth. 2 millions light years away from us, yet it's our neighbor
HI, Milky way is 100000 by 1000 LY across, Andromeda is 2.5 MLY away, so it wont be in our own galaxy, what we are looking at is from arm Number 4 of the milky way. That's where we are.

Andromeda is such a cool name!
We should have named OUR Galaxy Andromeda!
Instead we got stuck with that lousy Milky way! =(
