The convex secondary mirror multiplies the effective focal length of the primary mirror and results in a focus at the focal plane, with light passing through a central perforation in the primary mirror. The 8", 10", and 12" models include oversize 8.25", 10.375" and 12.375" primary mirrors, respectively, yielding fully illuminated fields- of-view significantly wider than is possible with standard-size primary mirrors. Note that light ray (2) in the figure would be lost entirely, except for the oversize primary. It is this phenomenon which results in Meade 8", 10", and 12" Schmidt-Cassegrains having off-axis field illuminations 10% greater, aperture-for-aperture, than other Schmidt-Cassegrains utilizing standard-size primary mirrors. The optical design of the 4" Model 2045D is almost identical but does not include an oversize primary, since the effect in this case is small.

While heading out for The Greek philosopher Heraclitus of Ephesus, said 2500 years ago that the its rendezvous with Jupiter, a camera on NASA's Galileo perceptible world is always changing. spacecraft snapped this 1992 image of Earth and its Moon. The Heraclitus was not mainstream, of course.

Image courtesy of change and motion are logically impossible. And Aristotle, much admired in NASA. ancient Greece and Rome, and the ultimate authority in medieval Europe, declared "...the earth does not move..." We today know that Heraclitus was right, Aristotle was wrong, and Zeno...was a philosopher. Everything in the heavens moves, from the Earth on which we ride to the stars in the most distant galaxies. As James B. Kaler has pointed out in The Ever-Changing Sky: "The astronomer quickly learns that nothing is truly stationary. There are no fixed reference frames..." The Earth's motions in space establish our basic units of time measurement and the yearly cycle of the seasons.

  • Measuring the Sky
    MEASURING THE SKY A Quick Guide to the Celestial Sphere By Jim Kaler Return to STARS or SKYLIGHTS THE CELESTIAL SPHERE We observe the sky as it looks , not as it is . You feel like you are on top of the Earth (the result of gravity drawing you toward the Earth's center). In the example, you are at a latitude (your location along an arc from the Earth's equator to the rotation pole, given by lower case Greek letter Phi) of 45°, halfway between the Earth's equator and the north pole. The latitude of the north pole is 90°, that of the equator 0°. The Earth appears to lie at the center of a fictional celestial sphere . You pretend that you are inside the sphere at the center looking out around you. Above your head is your zenith , while directly below you is your nadir (both of which are points on the celestial sphere). In between is the great circle of the horizon , which is the circle on the celestial sphere cut by a plane tangent to the Earth at your feet. Everything in the sky above the horizon is visible, while everything below it is not. The celestial sphere is tipped relative to the observer in the same way as is the Earth. The extension of the Earth's rotation axis to the sky defines the North and South Celestial Poles (the NCP and SCP), while the extension of the Earth's equatorial plane defines the celestial equator . The NCP is in the constellation Ursa Minor (the Smaller Bear) close to the direction of the star Polaris , otherwise called the North Star .

  • The COLOUR of CREATION Observing and Astrophotography Targets “At a Glance” Guide
    The COLOUR of CREATION observing and astrophotography targets “at a glance” guide. (Naked eye, binoculars, small and “monster” scopes) Dear fellow amateur astronomer. Please note - this is a work in progress – compiled from several sources - and undoubtedly WILL contain inaccuracies. It would therefor be HIGHLY appreciated if readers would be so kind as to forward ANY corrections and/ or additions (as the document is still obviously incomplete) to: [email protected]. The document will be updated/ revised/ expanded* on a regular basis, replacing the existing document on the ASSA Pretoria website, as well as on the website: coloursofcreation.co.za . This is by no means intended to be a complete nor an exhaustive listing, but rather an “at a glance guide” (2nd column), that will hopefully assist in choosing or eliminating certain objects in a specific constellation for further research, to determine suitability for observation or astrophotography. There is NO copy right - download at will. Warm regards.
