The Andromeda Galaxy got a little closer to us.
The Sun rose in the East this morning, and then set in the West later in the day.

The short answer is no, but they are damn handy.
Most telescopes these days have computers that slew and drive little stepper motors to track the sky. They are able to point to a planet, star, galaxy, nebulae and a variety of other objects at the push of a button.

For some reason, my sidebar no longer shows the page I had dedicated to the Mars Opposition. Since we’re getting pretty close, I thought I’d put this up again:

[I wrote this a while back but wanted to bring this to the top of the blog for those who may be looking for a scope for Christmas. Back when I wrote this, I think I had about three readers.]

If you think you’d like to get your astronomy buff a telescope this year for Christmas, but aren’t sure what to get, then I’ll list some choices that I think are pretty good.

Magnification is irrelevant. Most telescopes operate between 30 to 70 power for visual use. […]
