Meade LX850 Mount with Starlock and 10" ACF f/8 Advanced Coma Free Tube
Building on Meade´s award winning Advanced Coma Free (ACF) optics, the LX850 employs a fast f/8 optical system with high-contrast baffling that assures crisp, pinpoint imaging to the very edge of the field.
The all-new OTAs feature an internal Crayford-style, zero image shift focusing system with a two-speed, 7:1 control that rigidly holds the primary mirror, eliminating the need for a mirror lock. In addition, with the LX850s optional large-format, three element f/5 focal reducer / field flattener, you gain even wider fields, faster exposures and a flat field on larger sensors.
The new Meade LX850 equatorial mount
is made from machined high-strength
aluminium and stainless steel and is the stable and precise mounting
system for optics up to 14 for visual observing and astrophotography.
This precision is reached through the use of large 147 mm worm drives
and 17 mm diameter worm gears. The GPS assisted AutoStar computer
control positions 144.000 celestial objects from its database. The
ultra-stable tripod is a solid base.
The Meade StarLock is a
extremely precise system, allowing for precise positioning and tracking.
The two built-in cameras using two different focal lengths complement
each other well. The wide field camera helps with rough positioning,
whilst the long-focal length optics is used to precisely locate guiding
stars with an accuracy up to one arc minute.
The alignment is
also done using these two cameras. They bring the alignment stars in the
center of the field of view and therefore provide the basis for optimal
To enhance the tracking accuracy to the maximum
possible, the StarLock provides a permanent and automatic autoguiding.
After slewing to the desired position (e.g. after using the GoTo
function), the guiding camera automatically picks an appropriate guide
star up to mag 11. This star is tracked to guide the system, until it is
slewed to another object.
The Drift Alignment Assistant enables
the perfect parallactic positioning of the mount. The LX850 selects the
appropriate star. Automatic inspection of a 30 seconds image using the
wide field camera yields the misalignment in relation to the true north.
Now the LX850 slews to the nominal position. Using the fine adjustment
of the mout, the pointing of the RA axis is subsequently corrected.
two StarLock cameras are also capable of aligning the LX850 fully
automatic, without any user interaction. This alignment method has been
invented with the popular Meade LightSwitch Telescope.Data of StarLock:Wide Field Camera:
