Subject: Images: IR Uranus and by daylight

Hi all;
I've updated my website with some images;
Uranus, imaged in IR band with a 1 micron pass-band filter shows details;
the bright south polar cap is clearly visible in my CCD image (not webcam):
http://www.danielegasparri.com/amateur_astronomy/images/html_eng/uranus_060929.htm .
I hope this image can finally prove what I'm saying since 2 years: it is
possible to capture details on Uranus; some my past images were criticised a
lot, but I went ahead, and I hope this time someone might believe me.
The second one is a collage of many images taken during the day, with the
sun high above the horizon. Many persons think that astronomy is a
night-hobby, but with the right equipment it is possible to image all the
planets (excepted for Uranus and Neptune), included the Galileian moons and
some bright stars. The result are very good especially for the Moon and
inner planets (Venus and Mercury), while Jupiter and Saturn show easily the
most important features:

Clear skies!

Not sure that amateur scope can do bettert.
To compare to these images (end of page) with C14 and 250mm

The (very good) images in the link are all taken in visible light, where
Uranus is a smooth and uniform blue-green ball (at least for small scopes);
Its aspect changes in IR light; longer is the wavelenght, greater is the
contrast of the south polar cap (until 2 microns); at I and J photometric
bands, the polar cap is quite bright, and the feature is recordable with
smaller telescopes (we have just to record the photometric changing, like
the Encke minima on Saturn, not necessarily the real detail, so it's not
very important the scope diameter, but the wavelenght and the camera used
(16bit cooled, with dark frames subtraction)). I used a CCD camera and 20"
exposures, in two different nights, and the images match perfectly.
We should also consider the images taken by Rolando Chavez::
http://www.buytelescopes.com/gallery/view_photo.asp?pid=9961&sg=1&page=2
(and the judgments of some important persons..see the link); those are
remarkable since are taken without an IR filter (thanks to a larger
telescope diameter maybe), and both (mine and Chavez's) match perfectly with
the Hubble pictures, and keck's:

Fascinating, Daniele. Both your Uranus IR image and the daylight
astronomy images were great. Thanks for sharing!

I didn't realise it was 'Min' until after my post. Should have known him
from the other 'conspiracists' who got their education from Oliver Stone,
Michael Moore, and other Hollywood history 'teachers,' lol.

Im not surprised at all you have done the good Uranus. You have
been turning out superb work all along. Congrats -
