Cassini; Blue Expanse & Titan “T28” Mosaic.

Cassini infrared image from above the planet’s northern latitudes. Nearly the full expanse of the main rings is visible here -- from the C ring to the outer edge of the A ring (in the upper left corner).


Cassini mosaic of images taken during the T28 flyby in April 2007.

Oops... just spotted this on another website, from May 22th 2007 Astronomy Picture of the day.

Click on the image to play the quicktime mov, get it to run in loop mode. Shows the structure/dynamics of the Sun's surface really well.

HiRISE update: Possible cave entrance on Mars

This image is from the HiRISE spacecraft currently orbiting Mars. This is an intriguing picture, the HiRise camera can see into most of the darkest shadows on Mars, but is unable to penetrate this.

Images from 24th May Moon session

Albategnius & Klein

The Apollo 11 landing site, just up and to the left of the bright crater at the bottom right.

Old Apollo landing sites.

Here's something interesting... I found an old National Geographic Moon map in a bookshop today, dated February 1969. On the map it had some markings for Apollo landing sites.
There is a larger version here.

Moon 24th May 2007

Here's another Moon taken with my Canon Powershot, handheld at a 32mm EP.
(I must get around to buying one of those clamp things one of these days)

Here is a slightly larger version.

And here is a higher contrast version, processed with Registax and wavelets.

Beware; large file sizes.

Venus 14th May 2007

James Webb Space Telescope.

JWST will have a large mirror, 6.5 meters (21.3 feet) in diameter and a sunshield the size of a tennis court. Both the mirror and sunshade won't fit onto the rocket fully open, so both will fold up and open only once JWST is in outer space. JWST will reside in an orbit about 1.5 million km (1 million miles) from the Earth.

Can't wait for this!

Bye Bye Saturn

Scopes back... game on.

My scope mount is back and fixed from David Hinds. New RA motor, fixed under warranty... now that makes a change.

Took this image of Venus last night. Venus is a tricky planet to image... I'm finding out.
I don't think the scope was properly cooled down either. But it's nice to be out again. :-)
