The Celestron AstroMaster-90 is a very good telescope for beginners. It is ideal for both terrestrial and celestial applications. The AstroMaster-90 offers multi-coated glass optics to allow clear and crisp images. This refractor model can also be used for astrophotography with an appropriate T-Mount adapter. It comes with a rugged pre-assembled tripod, 20mm eyepiece, 10mm eyepiece, and a permanent mounted Starpointer finder scope to easily locate heavenly objects.

Based on Astronomy magazine’s telescope "report cards", scopes of this size and type generally perform as follows . . .
Terrestrial Observation: Observing terrestrial objects (nature studies, birding, etc.) is usually possible only with refractor and catadioptric telescopes, and convenient only when the scope is on an altazimuth mount or photo tripod. Most reflectors cannot be used for terrestrial observing. Scopes with apertures under 5" to 6" are generally most useful for terrestrial observing due to atmospheric conditions (heat waves and mirage, dust, haze, etc.) that degrade the image quality in larger scopes.	No
Lunar Observation: Visual observation of the Moon is possible with any telescope. Larger aperture scopes will provide more detail than smaller scopes, thereby getting a higher score in this category, but may require an eyepiece filter to cut down the greater glare from the Moon's sunlit surface so small details can be seen more easily. Lunar observing is more rewarding when the Moon is waxing or waning as the changing sun angle casts constantly varying shadows to reveal craters and surface features by the hundreds.	Great
Planetary Observation:	Very Good
Binary and Star Cluster Observation:	Very Good
Galaxy and Nebula Observation:	Fair
Photography:	Yes
Terrestrial Photography: Photographing terrestrial objects (wildlife, scenery, etc.) is usually possible only with refractor and catadioptric telescopes, and convenient only when the scope is on an altazimuth mount or photo tripod. Most reflectors cannot be used for terrestrial photography. Scopes with focal ratios of f/10 and faster and apertures under 5" to 6" are generally the most useful for terrestrial photography due to atmospheric conditions (heat waves and mirage, dust, haze, etc.) that degrade the image quality in larger scopes.	No
Lunar Photography: Photography of the Moon is possible with virtually any telescope, using a 35mm camera, DSLR, or CCD-based webcam (planetary imager). While an equatorial mount with a motor drive is not strictly essential, as the exposure times will be very short, such a mount would be helpful to improve image sharpness, particularly with webcam-type cameras that take a series of exposures over time and stack them together. Reflectors may require a Barlow lens to let the camera reach focus.	Yes
Planetary Photography:	Yes
Star Cluster / Nebula / Galaxy Photography:	No
Warranty:	2 years
