The Meade 8" LX200 ACF telescope handles your observing and imaging needs with ease. Incredibly compact for its aperture, yet with a robust and solid fork arm mounting for a vibration free image. Push button controls, automatic locating and tracking of celestial objects, and a wealth of object data at your fingertips in the AutoStar II hand controller. A mechanical mirror lock will completely eliminate any residual image shift — ideal for astro-imagers. Both visual astronomers and astrophotographers alike will appreciate the quality and capability of this beautifully made telescope.
The included 8" Equatorial Wedge is designed specifically for 8" telescopes and converts your alt-azimuth telescope into a system ready for long exposure astrophotography. Featuring heavy duty cast aluminum construction with latitude and longitude fine adjustments, and a compass to use the magnetic pole as a starting reference. The equatorial wedge is mounted between a telescope and the tripod to accomplish the tilt of an equatorial type mount that matches the observer's latitude and permits precise polar alignment of your telescope. The wedge allows the astrophotographer to align the telescope's axis of rotation with the Earth's axis of rotation. This alignment eliminates stars in your long exposure photograph from appearing as a long arc, trail or streak due to an effect known as field rotation. For short planetary and lunar photography, a wedge is not necessary and the telescope can be set up in altitude-azimuth (alt-az) configuration as normally used for visual observation.
Equatorially mounted telescopes with fork mounts like this LX200 bundle have several distinct advantages over German EQ telescopes. For one, the fork mounted configuration doesn't require any pier flip when tracking across the meridian. It can track continuously across the meridian without interruption. All German equatorial telescopes must stop tracking near the meridian to flip to the other side of the mount, re-acquire the target, and stabilize guiding, before imaging of the object can continue. It is a big inconvenience that is avoided with fork mounted telescopes. Another advantage of the LX90's fork-mounted EQ configuration is that it does not require counterweights — so, less heavy stuff to haul around. And lastly, fork mounted telescopes typically have smaller footprints compared to their standard EQ counterparts, making them ideal telescopes for small observatories. They're super versatile as they can be configured between the simple to use alt-azimuth mode or equatorial mode by merely adding or removing the wedge.
The 8" LX200-ACF features an 8" aperture, 2000mm focal length, and f/10 focal ratio with Dual-Fork Mounting. Equipped with Ultra High Transmission Coatings (UHTC) and a resolving power of 0.570 arc-seconds for the improvement of brighter star clusters, more fine detail in nebulae, and greater surface features on planets. Includes a Series 4000 26mm Super Plössl eyepiece (77x), viewfinder (8x50 optical with crosshair), 1.25" Diagonal Mirror, and Standard Field Tripod. OTA Dimensions: 9" x 17" L. Assembled Telescope Weight with wedge: 84 lbs. Tripod Weight: 19 lbs. Tripod Dimensions: 30" to 44" variable.
Designed and Manufactured in North America.
The ACF primary, secondary and corrector plate glass blanks are manufactured in the USA exclusively for Meade. Meade ACF telescopes, including the mounts, are manufactured and assembled in North America.
Features AutoStar II computer system with 145,000 object-library, multiple guided tours, High Precision Pointing capability with sub arc-minute pointing accuracy, and Meade SmartDrive with Permanent Periodic Error Correction.
The optical path and components of the ACF telescope design
Precise and quick star alignment is done near effortlessly with Meade's level north technology alignment system incorporating a 16-channel GPS receiver. Drive base of the telescope has multiple input/output ports including an RS-232 PC interface and jacks for a CCD Autoguider (user-supplied) and illuminated reticle.
Mechanically loaded as well, all LX200 models feature a primary mirror locking mechanism, which effectively prevents movement of the primary mirror during long-exposure astrophotography or observing. Turn the lock knob located just above the telescopes main focus knob and the progressive-tension primary lock completely cancels any residual image shift due to mirror movement during visual, photographic, or imaging applications.
Features the DC-servo driven, super heavy-duty dual-fork mount — the strongest and most rigid mount in its class. Fast slew speeds are from 1 to 8-degrees per second, and can be user selected at 0.1-degree per second increments, while fine slewing and photographic guiding speeds can be adjusted from .01x to 1x sidereal in one one-hundredth increments. Mount and electronics are internally powered by 8 C-cell (user-supplied) batteries which will typically operate the telescope for around 20 hours (optional Meade Universal AC Adapter also available). The mount also has mechanical locks and slow motion manual controls in both axis if no power is available.
Meade's LX200 is the most widely used, research-grade telescope system. And now, you can have one too.
