The
Total Lunar Eclipse of 2008. A movie by Theo Ramakers!

Two images of Mars, showing my progress in imaging. The first was made the night of September 8-9 2007 when Mars was still a very small 8.5 arc seconds and had a magnatude of 0.18. My imaging skills were in its very infacy stages and to image the small object was pretty tough for me. I was pretty happy though to see Hellas (Bright spot at the top) Syrtis Major (The dark area accross the equator) and the North Polar cap at the bottom. The image is South up.
The next image is from December 12-13
2007. Stability was not good at all. I got the color balance much
better but could not get the focus right. However visible are
the Northern Polar cap, Oxia Palis (just off the center) and
Niliacus Lacus (Justbelow the center) as well as clouds just below
the polar cap. (North is down)

Comet 17PHolmes October 2007 The explosion of comet 17P/Holmes was a pretty exciting event for all of us. The comet returned every 6.9 years but we never witnessed an event that lead to its discovery in 1892, an explosion so bright that the comet became visible to the naked eye. I feverishly spend every night following the 24th of October watching the comet to see how it expanded. I made hundereds of images. The best way to present the excitement associated with the comet was by putting some of the images in a movie so you also can see why we were so excited. The cloud surrounding the comet became bigger than the orbit of the moon in a matter of one week, and large than the sun in three weeks. Click here to see the movie.

7 Days of 17P/Holmes
I managed to image the Comet from
10/25 until 10/31 every night, alowing me to put togeher this
image. Each image is aligned with the one next to it by
aligning the overlapping stars in each image. The result is a
representation of the comet over 7 days showing how it moved
against the backgrond stars and the effect the expansion had on
the relative luminance per arc second over the same
period. Each image is 5 sec. at ISO1600 with the Canon Xti 400D
through the Celestron CPC in prime focus.
Smiling Cats face...(Doesn't it
look like that?)
Line up of Venus, Regulus, Moon and
Saturn. The early morning of October 7th 2007 was the
opportunity to get these objects lined up in one picture. Image
is a 1.3 sec exposure at ISO 1600 with the Canon Xti 400D taken
at 5:54 am ET from social Circle GA. Venus is on the right,
Regulus to the left of Venus, than the moon and at the bottom is
Saturn.

One week of Comet 17P/Holmes
The following image shows the expansion
of 17P/Holms starting one day after the discovery of its
"explosion", from 10/25 until 10/31 from Social Circle, GA and the
associated decrease in luminosity per arc second. The expansion
image is composed of 7 images, one per day, taken with the CPC 9.25
and a Canon XTi 400D in prime focus. Exposure on each day is 5 Sec
at ISO 1600. The moving image is a series of 17 images taken on
10/31 over a 4 hour period in 15 minute intervals from 9:00pm -
1:00am ET. Each exposure is 20 sec. at ISO 1600.
17P/Holmes Continued
I thought it to be nice to show the
following two images from 17P/Holmes on its 115th discovery
anniversary date. The close up is a single 20 sec exposure on the
Canon XTi 400D in prime focus through the CPC 9.25. The wide angle
shot is a 30 sec exposure at ISO 1600 using its original lens.

The attached images were captured
10/26/2007 of 17P/Holmes from Social Circle. The close up is a
stack of 37 images 4 seconds each, 400ISO with the 400D in prime
focus through my CPC925 stacked in Registax.
The sky view version is made with the
Canon at 115 mm. direct from a tripot, 8 sec @ 1600 ISO at F5.6
