Model visualizes current position of comet, assumed trajectory and all important moments. It also contains interesting features such as movement in time or realistic mode. Soon they will add also view from the Earth. Courtesy of Michal Sadlon www.inove.eu.com

M57 Discovery Images

Here is a nice image showing the discovery images of the halo's of M57 from 1937 and 1987 together with our image of M57. It nicely shows the developments in astrophotography and what can be acheived today with quite modest amateur equipment.

Hubble Comparison

This image shows the result of close cooperation between 5 astronomers (André van der Hoeven, Terry Hancock, Fred Herrman, Mike van den Berg and Mathijn Ippel) who have imaged M57 for over 100 hours in total. On the right is the result from the Hubble Space Telescope with the halo as imaged by the Subaru 8.2 m telescope in Hawaii. The result of the amateur image shows what current imaging equipment is capable of and It nicely shows the signal that we measured are real phenomenon in the shells.

                                               Comet Ison

One of the most exciting imaging projects I have been involved in. This time with my good friend and student Mr. Cliff Spohn who has been capturing ISON from his remote observatory in Marion Ohio. We hope to present more images of ISON soon but the window of opportunity narrows as it nears the sun





please visit my exhibit, prints can be purchased at the gallery now
