I finally found some time to combine 3 images of comet Holmes taken with our 16'' telescope and a ST-9E. This animation shows the magnitude of what happened. To get a sense of scale, I added Jupiter to the animation. It thus shows what it would have looked like if Jupiter and Holmes were side by side and if they were at the same distance to Earth.

Here's a vertical widefield image of comet Holmes with associated constellations and bright stars taken from my back garden. I estimated the comet at mag +2.2 and I could see the comet's coma easily with the naked eye!

Photo details: FujiS5600 5.1MP at ISO800 15 sec exp at F.3.2

A six second photo taken through a Takahashi 6"APO refractor using a digital Nikon set to ISO1600. Especially noteworthy are three 11th magnitude stars shining through the coma of the comet. Photo taken 10/28/07 at 00:30UT.

I got this image of Comet 17P/Holmes just before moonrise. You can now clearly see the coma disk even through the fog and high clouds.

Expanding 17P/Holmes from combined B, V, R images taken with an Apogee Alta CCD on the Michigan State University 24-inch telescope. 1:05 UT.

Photo details: Nikon D70 DSLR camera on a GOTO-45cm Cassegrain Reflector with 2X Tele-converter , 200~400 ASA, 30~62s exposure.

The size and color changes on 17P/Holmes in 48 hours 25 and 27 October 23:20 UT. Takahashi Sky90 and Nikon D70.

Dust and gas: 17PHolmes is now showing both CO gas (green external disk) and dust (yellow internal disk). Imaged with a Schmidt Camera, 30 cm f/2.0 + CCD, total exposure 22 min. In the line profile graph it's evident that the external disk is dominated by green emission of gas. (log values, sun direction toward positive values)

Multi-wavelength imaging of the comet 17P/Holmes

I captured so a fantastic feature of Comet Holmes. The bigger comet has the expanding dust cloud from a initial explosion. 80cm Nasmyth telescope(F10), Canon EOS 30D, 8sX20 exposure

Very impressive now, and very large!
