![]() ![]() The Sirius 8 is a serious buy for any astronomer in the market for a telescope. ![]() The Meade telescope is expensive, but it’s priced this way for good reasons. It is an alt-azimuth, double fork-arm mount, but a wedge can be incorporated for improved polar axis tracking. Everything is done through the AutoStar computer that is conveniently packaged into a hand control. The LX90 has a GoTo mount with multiple features that includes GPS, AutoAlign, SmartDrive, and more. Wide-angle eyepieces can be incorporated, there isn’t any coma interfering with the image, and its visibility quality extends to DSOs. What this means for you is excellent correction of aberrations that would normally plague this type of scope.ĭue to its optical quality, its narrower field of view with focal ratio of f/10 is of less concern because what you can see looks brilliant through the scope. The ACF (Advanced Coma-Free) optics consists of an SCT variant by way of a hyperbolic secondary mirror and a full aperture aspheric corrector lens. What adds to its optical quality is the UHTC coatings that improves light transmission. It has a folded light path, uses both mirrors and lenses, and has great control over aberrations. It’s a Schmidt-Cassegrain (SCT) telescope that is known for its long focal length and yet compact and short tube. It has a great 8” aperture for seeing almost any object within the Messier, Caldwell, and Herschel Catalogs. The Meade telescope is one of the more serious ones in the market aimed towards intermediate and advanced users. ![]()
