AstroTrac - AstroTrac TT320X Tracking Mount
The AstroTrac TT320X is the new and improved version of the AstroTrac
TT320, a motorized camera tracking mount that allows you to take up to two
hour exposures with your film or digital SLR camera without star trails!
The X version of the TT320 has a larger load capacity of 33 pounds, and it
is more accurate than the popular AstroTrac TT320; with a typical unguided
tracking error of about 5 arc seconds peak-to-peak over a period of five
minutes.
Simply attach the AstroTrac TT320X mount, which only weighs 2.4 pounds, to
a photographic tripod, attach your camera and lens (or small telescope &
camera), do a quick alignment, start your exposure.. and in minutes, you
will have captured beautiful images of the Milky Way, nebulae, star
clusters, galaxies, and more!
Choose sidereal, lunar, or solar tracking rates...a nice choice for solar
imaging with the PST or Lunt scopes!
