The Meade 10" LX90-ACF Telescope
yields similar optical brilliance to the LX200 flagships, but in a
package providing better value for those primarily observing rather than
imaging. The quality, workmanship, design, and features will satisfy
novices and experienced professionals alike. This is the "ACF" version
of the 10" LX90, which stands for "Advanced Coma-Free". Meade has
employed advancements beyond the traditional Schmidt-Cassegrain
catadioptrics for the LX90-ACF, gaining significant resolution increases
as you move away from the center of the field towards the edge.
The 10" LX90-ACF with UHTC multicoatings is a serious deep space
aperture instrument, but is still of a size that can be managed by one
able-bodied person. It provides a notable difference in brightness and
resolving power versus the more common 8" catadioptric scopes. To truly
appreciate the aperture, you'll need dark skies above you, whether
you're blessed not to live amongst artificial light pollution or able to
commute to a similar location for observing purposes.
Meade combines high quality optics, stable double fork mounting,
computerized control, and streamlined appearance in a single unit. The
list of technology within is long and exhaustive: a rigid mount with
beefy tripod, an oversized primary mirror, truly diffraction-limited
optics, and the very finest of simple and accurate GPS-enabled
alignment.
The 10" LX90-ACF's standard-equipment AutoStar computer controller
connects to the telescope's control panel and permits viewing and
tracking of 30,223 database objects. That's 50 objects in the solar
system, 8 major planets from Mercury to Pluto, the Moon, 26 asteroids
& 15 comets. An apparent endless supply of galaxies, diffuse
nebulae, planetary nebulae and star clusters are present, including the
complete Messier, Caldwell, IC, and NGC catalogs. You'll also enjoy
looking at 50 satellites, including the International Space Station and
the Hubble telescope.
You can do some light-duty lunar/planetary imaging (of up to ~5 minute exposures)
with the LX90 through the eyepiece using a digiscoping adapter or with
an SLR via the SLR adapter and your camera system's specific
T-mount. For deep space images of exposures much longer than a few
minutes, you'll need a Meade Deep Sky Imager; the 10" LX90 cannot use a
wedge and thus cannot make streak-free long exposures with an SLR camera
(the Deep Sky Imager's software corrects for field rotation).
Power for the LX90-ACF is supplied by 8 "C" batteries, but via
optional accessories you can also adapt to an AC wall unit or a
vehicle's cigarette lighter (which can operate in the field off of a Celestron Power Tank). Everything needed to begin observing immediately is included except for the power supply.
