... The remote planet Pluto and its moon Charon orbit the Sun at a mean distance of almost 6,000 million kilometres, or nearly fourty times farther out than the Earth. During a recent investigation by an international group of astronomers [1], the best picture ever of Pluto and Charon [2] was secured with the European Space Agency's Faint Object Camera at the Hubble Space Telescope (HST). ... The new HST image was taken when Charon was near its maximum elongation from Pluto (0.9 arcseconds). ...

5. Planetary Radar: Arecibo Radar Images of Asteroids
This series of delay-doppler radar images of the asteroid 4769 Castalia (also known as 1989 PB) were taken at approximately 2 minute intervals on 1989 August 22 at the Arecibo Observatory. ... These images have been stretched to look decent on a browser, rather than for accuracy. ... Thus these images have a frequency resolution of 0.24 Hz (~40 m), and a frequency sampling of 0.12 Hz, but the signal to noise ratio should be 2 times worse, as only 6 looks can be summed. ...

15. The pyramidal (multi-resolution) CCT
... The value of tile-size, NW , may be thought of as a sixth coordinate axis in the chirplet transform parameter space - TF-area. Including this sixth coordinate axis provides us with a hierarchical (multi-resolution) CCT. ...

17. Resolution - an Astronomy Net Astrophotography Forum Message
Astrophotography Forum Message . ... The resolution of a CCD camera does not depend on the number of pixels in the camera, rather it depends on the size of the pixels making up the chip and the focal length of the lens forming the image. ... A larger chip made from the same substrate will have identical pixel sizes, just more of them. ... With a fixed focal length telescope we don't have that luxury, in which case smaller pixel size rather than larger chip size is the only way to increase resolution. ...
