This is a shot from our east facing bedroom window at dawn this
morning from southeast England with at least 5 planes from the
Americas overflying for touchdown in nearby Europe within the hour.

Welcome America!

With Cheney and Rumsfeld running things, you're lucky they're not
bombers. Or perhaps they are, but they're headed for France. Vive la
France!

Nice, but I have a suggestion that I hope you will see as constructive.
Your images exhibit significant compression artifacts, which,
unfortunately, are evident as blocky distortion around white,
sharp-edged regions such as the planets and stars and your white type.
This distortion blurs the affected areas, which is especially
undesirable with images of stars and planets, as they are no longer
reproduced as sharp points. This distortion is generally caused by one
of two things: your choice of excessive compression when you saved the
image as a JPEG; or the use of software whose resampling and
compression algorithms are not up to snuff. I can't tell which of these
factors affects your images. If it's the former, move the "quality"
slider or its equivalent in your app to a higher level. If it's the
latter, I would note that many shareware/freeware graphics
applications, particularly on the Wintel platform, fall down in this
area. This is not true of Photoshop and other high-end graphics apps,
which work about as well on Wintel as they do on the Mac. I'm not
suggesting that you drop £534 on Photoshop; Photoshop Elements @ £68
(amazon.co.uk) is a good choice for either platform.

If you're using film and scanning negatives or prints, don't scan at
low resolution even if you aren't planning to print an image. Scan at
about 300 pixels/inch and in TIFF or Photoshop format (lossless
formats) and then let your image editing software -- which almost
certainly has better algorithms than your scanner software -- do the
JPEG resampling and compression.

Hi Maurice,

I enjoyed your pictures! Watching the planets change and form =
interesting naked-eye patterns is one of my favorite astronomical =
activities. ;-)
