What can you see together with an ETX90? You won't see the flag on the Moon, but you will see sharp, color free views of mountains and valleys, craters, and lava flows. The planets are in addition a delight. I'll never not recall seeing Saturn's rings together with my own eyes for the first time. Although you can see the rings of Saturn and the cloud bands of Jupiter together with the integrated 26mm Plossl eyepiece (concerning 48X magnification), you'll would like to enhance the magnification to get out extra detail. I locate this a magnification of concerning 100X is perfect on much nights. You can reach 100X by utilizing a Barlow Lens, I like the Celestron Ultima Barlow, or a smaller eyepiece such as the Celestron Omni Series 12.5mm . It's tempting to crank up the power to 200X or extra, but on much nights I didn't see any extra detail.
Many of the excellent galaxies and star clusters were discovered by a French comet hunter named Charles Messier. These so-called "M" objects looked to Messier like comets in the small telescopes of his day. My first night together with the ETX, I switched on the "tour" mode. Afterwards looking at a few favorites, the cluster M52 came up on the Autostar. I pressed GO TO, and the telescope aimed itself at a cluster I hadn't looked at before. And darned if it didn't look just like a distant comet passing in front of a few small stars! I was so impressed, I purchased an ETX for my step-son who works for the Air Force.
It's only fair to warn you, however, this if you locate yourself enjoying astronomy, you may begin wanting a bigger telescope! --Jeff Phillips

The ETX-90EC in addition consists of high-torque DC motors on together telescope axes, permitting electronic operation from the handheld controller. This pushbutton electronic controller has four dual-axis drive speeds: slow, 8x for picture centering at high power; medium, 32x for picture centering at lower power or for pushbutton tracking in altazimuth mode; moderate, 0.75 degrees per second for picture centering in the viewfinder or for terrestrial tracking; and quick, 5 degrees per second for quick scanning across the sky.
The Meade ETX-90EC is specially intended to be portable and used in the field. It proposes cordless operation, allowing you to use the telescope's dual-axis drive system for extra than 40 hours on eight AA batteries. At approximately 8 pounds, and 15 inches in length, it packs a lot of power into a compact unit.
The ETX-90EC uses a 90mm Maksutov-Cassegrain optical design. Meade in addition uses EMC super-multicoatings on all optical surfaces to maximize light transmission throughout the corrector lens and reflectance from the primary and secondary mirrors. The flip-mirror system lets for 90-degree observation of land and sky objects, straight-throughout observation utilizing the optional 45-degree erecting prism, or photo-ready imaging utilizing the optional T-adapter and your own 35mm camera.
The Nuts and Bolts
1. Eyepiece 2. Viewfinder 3. Eyepiece Holder Thumbscrew - Tightens the eyepiece in situate. 4. 90° Eyepiece Holder - Holds the eyepiece upright for simple viewing. 5. Optical Tube - The main optical component this gathers the light from distant objects and delivers this light to a focus for examination together with the eyepiece. 6. Vertical Lock - Controls the manual vertical movement of the telescope. 7. Fork Arms - Hold the optical tube in situate. 8. Focus Knob - Moves the telescope’s optical tube in a finely-controlled motion to achieve precise picture focus. 9. Horizontal Lock - Controls the manual horizontal rotation of the telescope.
10. Computer Control Panel
11. Base Housing - Maintains the telescope for positioning on a flat, altitude surface, such as a tabletop or optional tripod. 12. Holes for Optional Tripod - See your tripod’s instruction sheet for mounting information. 13. Right Ascension (R.A.) Environment Circle. 14. Flip-Mirror and Flip-Mirror Control Knobs - ETX telescopes contain an internal mirror. Together with the flipmirror control in the "up" position, light is diverted to the eyepiece. Together with the flipmirror control in the "down" position, as shown in Fig. 2b, light proceeds straight out the photo port for photography. 15. Photo Port - Attach any 35mm camera together with a removable lens to this port utilizing an optional adapter. 16. Declination Environment Circle (on left fork arm). 17. Viewfinder Alignment Screws - change these screws to align the viewfinder. 18. Viewfinder Alignment Bracket. 19. Dust Cap 20. Battery Compartment (not shown, beneath base).
