This is the final part of my three part review devoted to the ETX-LS. It focuses on the computerized mount and how it performed over a series of observing sessions. I conclude with my final thoughts on using the Meade ETX-LS.
Part one covered my brief impression of the physical characteristics of the telescope after setup and a brief night out under the stars. Now that I have had a chance to take the ETX-LS out for a few long observing sessions, how did the ETX-LS perform optically? Find out more.
Mostly good Chinese made scope with just a couple of irritations.
A unbeatable combo for Oklahoma's rare great nights.
An unbiased review!
Disassembly, transport, and other adjustments to SCTs may result in gross miscollimation, where no "classic doughnut" is available to help in the adjustment process. Bad seeing also results in "bad doughnuts" which make collimation difficult. This article addresses these conditions, and provides some further pointers on SCT collimation.
4SE is a great begining!
A young amateur astronomer finds a winning scope
Certainly, a quality APO refractor is a favorite tool of the high-resolution aficionado, and a long-focus Newtonian reflector is also very desirable, but the cost of obtaining an adequate mount for the long and heavy tube assemblies may easily double the price of the telescope alone. This is where compound catadioptric scopes have found their niche in minimizing tube length and weight while still providing excellent image quality.
