The Internet is Wonderful

Filed under: astronomy, Astrophotography — Ed @ 7:49 pm

But I guess we all knew that… Today I got my camera mount for my telescope, along with my 3X Barlow (to replace the lousy one that came with my telescope) and right now (7:40pm) things look promising. Since I’m really wanting to get some astrophotography tonight, I figured I ought to go ahead and bite the bullet on figuring out how my German Equatorial Mount (GEM) works so that I could more easily track celestial objects while photographing them. For those of you who aren’t familiar with astrophotography, you can get your best results when taking exposures for a long time (more than a second – even minutes or hours sometimes). However, in order to take a good long duration photo (anything more than a small fraction of a second) you’re going to need to track the object in the sky. Because the earth is moving, the stars appear to move from east to west in the sky and unless you’re tracking them, your photo is going to be a bunch of streaks. The kind of mount I have (the GEM) allows me to be able to track objects by just adjusting one knob. It’s really quite clever; and also complicated. I hadn’t really figured out how to even use the thing properly yet since I wasn’t doing any longer term photography. Well now’s the time. I pulled up trusty Google and found both how to align a German Equatorial Mount and how to point a German Equatorial Mount. Both of these things are not obvious and unfortunately the instructions with my telescope mount merely tell how to assemble it, not how to use it. Now, I hope, armed with this knowledge I can get some good photos. I hope to have more to share after this evening.



  1. Hi Ed,I just posted a comment on your blog and suggested that you should get a mount that tracks……oops,maybe I should try reading your whole blog before posting comments….hahahahahaha
    Good luck with the new mount!
