It Was a Dark and Stormy Night ...

... so I had nothing better to do than raid my astrophotography archive to find pictures to post.

[Image 1] is a picture of Comet 17P/Holmes taken 11/23/2007. The comet is washed out because there was a Full Moon and my neighbor's flood lamp was shining directly at my telescope.

The image was produced using:

Camera: Nikon D80 (Piggyback onto ETX-125)
Lens: Quantaray 70-300mm (@300mm Focal Length)
ISO Speed: 200
F-Number: F/5.6
Exposure time: 48 Seconds
If you want to find out more about Comet 17P/Holmes, here are some excellent links:
Now lets have some rainy night fun ...

[Image 2] is a wide field picture I took of the constellation Sagittarius in August 2007.
[Image 3] is a 'film negative' view of Image 2.
[Image 4] is star chart of the constellation Sagittarius I found on

Using Images 4 as a guide, see how many Messier objects you can identify in Images 2 &3, and if you can link the visible stars in the constellation. Actually, connecting the dots (stars) will help you find the Messier objects.

The dense starfield in Sagittarius is the Heart of the Milky Way Galaxy. (This constellation and its many celestial treasures are what hooked me on Astronomy and Astrophotography).

Helpful Star Gazing Hint: In the light pollutes skies of Northern Virginia, I often take wide field pictures of portions of the sky and study them on the computer to learn my constellations and other celestial objects.

Blogger always messes up my formatting, so you have to go in and actually edit the HTML. UGH!
