Choosing and Using the New CAT will supersede the author’s successful Choosing and Using a Schmidt-Cassegrain Telescope, which has enjoyed enthusiastic support from the amateur astronomy community for the past seven years.
Since the first book was published, a lot has changed in the technology of amateur astronomy. The sophistication and variety of the telescopes available to amateurs has increased dramatically. Computerized SCTs, Maksutov-Cassegrains, and most recently Meade’s new and acclaimed Ritchey-Chrétiens have come to dominate the market. That means that all amateurs considering the purchase of a new telescope (not only a SCT, and not just beginners) will benefit from this detailed guide. Choosing the right telescope for particular kinds of observation (or even for general work) is far from easy – but Rod Mollise gives invaluable advice and guidance.

Telescopes. Actually, some of the best accessories for Meade and Celestron SCTs do not come from either company but from the hordes of aftermarket vendors large and small. SCTs have been in production and basically unchanged for nearly 40 years, and that means any accessory imaginable—focus motors, digital setting circle computers, electronic cameras, spectrographs, and much more—has probably already been made by somebody and will work on any Schmidt Cassegrain, old or new. As astronomy interests.
The scope is extremely solid and a joy to use. Which CAT? 65 Meade LX400-ACF 10-Inch The LX400 (Plate 20) does not come in an 8-inch version, so I have chosen to place the smallest model, the 10-inch, with the 8-inch SCTs rather than with the big CATs. That is because this is a remarkable scope in many ways, one that is worthy of consideration by anyone in the market for an SCT of any size, not just something for folks suffering from the dreaded aperture fever. What makes the LX400-ACF.
Admittedly, this model sports Questar’s advanced (and lovely) titanium tube, which is lighter than the standard aluminum and has somewhat better cooldown characteristics. If $11,000 is too rich for your blood, Questar will sell the OTA alone for “only” $8,775. Back in the 1960s, the Q7 was often referred to as a “doctor’s telescope.” That was not just because the scope’s gleaming stainless steel and aluminum body made it look at home in an operating theater, but because you would need to be a.
Balanced in declination. Initial Mounting Checks (Go-to Mount) The first step in checking out a go-to telescope’s mount is to go back and at least review the manual one last time. Is it time to head outdoors? Nope. Most go-to scopes are pretty user friendly these days, but it is a lot easier to learn to operate Making Friends with a CAT 123 them inside under normal lighting than it is out in a dark backyard. Indoors, it is easy to see the telescope is pointing to the ground instead of the.
Hardly! There are actually more print star atlases available now than there ever have been. Some amateurs do not own laptop computers, and not everybody who does wants to haul one out to a damp observing field. Sure, it is possible to print maps on a printer and take the hard copy onto the field, but many observers still like the convenience of a book of charts that covers the entire sky. What is desirable in a set of star charts? Let us mention what not to get first. Avoid “mag 6” atlases. These.
