By Rod Mollise

Amateur astronomy is changing into progressively more renowned, generally a result of availability of really inexpensive astronomical telescopes of amazing caliber - commercially-made Schmidt-Cassegrain and Maksutovs. Rod Mollise's booklet includes every thing beginner astronomers want to know approximately those telescopes. that includes (but no longer solely) the ever present Meade and Celestron levels, he describes what those tools will do, the right way to use them, and that are the easiest to decide on. This publication comprises every thing! There are sections on components, looking at suggestions, and tricks and assistance gleaned from his 25 years adventure with this kind of telescope: cleansing, collimating, protecting the telescope and mounting; utilizing the telescope in quite a few stipulations; laptop keep watch over; imaging (wet, electronic and CCD). this can be the suitable publication for newbie astronomers who're approximately to take a position in a brand new Schmidt-Cassegrain or Maksutov telescope, or in the event you have already got one and wish to get the simplest out of it.

Splitting the second - the story of atomic time

Astronomers have been traditionally the custodians of time, however the discovery that the interval of Earth's rotation isn't really consistent intended that they had to re-examine their simple devices. On a separate course, physicists constructed atomic clocks and held out the chance of a timekeeping procedure rooted in actual constants.

Vacuum ultraviolet spectroscopy

This quantity is for practitioners, experimentalists, and graduate scholars in utilized physics, rather within the fields of atomic and molecular physics, who paintings with vacuum ultraviolet purposes and are wanting deciding on the easiest kind of smooth instrumentation. It offers first-hand wisdom of the cutting-edge gear assets and offers technical details on the right way to use it, besides a large reference bibliography.

Example text

5 inch instruments are currently being marketed. With all the worry about size and weight, shouldn't these be even better than the 8 inch for the new stargazer? There's no denying that the portability of the smaller telescopes is a plus. A telescope which can be picked up tripod and all and easily moved outside on a moment's notice will get used a lot. But I do have reservations about telescopes of this size. When the aperture of a telescope sinks below 6 inches, its performance quickly nose-dives.

As supplied, the telescope comes with a wedge, but the tripod is an extra-cost option. The telescope doesn't come with a case either, but Meade's soft case cordura unit can be ordered for use with this unit. Like all current Meade SCTs, the enhanced multicoated optics group, MCOG, optical coatings for the mirrors and corrector plate are now standard. The telescope is currently only available with fllO focal ratio optics. If you want a Meade forkmounted SCT, this is as low as you go. It's an economy model for sure, but one which is surprisingly well appointed.

The on/off switch; plugs for the hand paddle, focus motor and declination motor; and the red power on LED are mounted vertically on the drive base. With the scope mounted on its wedge, this panel becomes very hard to see. Even the illuminated power light is not obvious. I like the LX-IO. In fact, it has been the only telescope I've used with my university astronomy classes for the last several years. Even jaded as I am by 25 years of SCT usage, I wouldn't mind having an LX-IO of my own. It's just a very competent CAT.
