Amazon : Sky Watcher Classic 200 Dobsonian 8-inch
Came in yesterday at 6:00 pm; two days ahead of schedule. Also bought a Shorty 1 2X Barlow lens, a 2X 2" Focal Extender, and a LaserMate Deluxe II Telescope Laser Collimator. I'm thinking about the Q70 (70 degrees) set of three eyepieces or the Explore Scientific 82 degree 2" eyepiece. I'm leaning toward the 82 Degree 2" eyepiece.

Parallax - Wikipedia
Parallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight, and is measured by the angle or semi-angle of inclination between those two lines. Due to foreshortening, nearby objects show a larger parallax than farther objects when observed from different positions, so parallax can be used to determine distances.
