ASTRONOMY

My First Lunar Mosiac!

83KB

Actually this is my first real astrophotograph. It's a lovely waxing crescent moon, don't you think? The large "crater" (actually, a "sea") in the image is Mare Crisium.

I took five images on May 7th, 2000 4:40 UT. I used a 90mm refractor with a 1000mm focal length (F11). Each image was taken in 3/100's of a second with a MX5-16 CCD camera at prime focus. Each image has been enhanced with a filter to enhance sharpness, but contrast was left as is.

As you can see from the images below, I'm working my way through theMessier objects, in the hopes of getting one of those Messier Certificates from The Astronomical League.

I'm going to have to go back and take better photos of some of these objects once I get more experience.

Please click on the thumbnail image to see the full resolution image and data about how and when it was taken. Click on the link for more information about the object itself.
