Explore Scientific Generation II Dobsonian Telescope

While the 16-inch aperture is substantial, the tool-free truss design makes it surprisingly manageable. The heaviest component, the mirror box, weighs 66 pounds, so while it is transportable, you will likely want a helper or a dedicated hand truck to move it comfortably to your observing site.

The integrated dual radial fans significantly speed up the process by pulling air across the mirror surface. Depending on the temperature difference between your storage area and the outdoors, you can typically expect the mirror to reach thermal equilibrium in about 30 to 45 minutes.

Yes, the 2-inch helical focuser is designed for precision and stability. With its 10:1 fine-tuning capability, it provides the smooth, incremental adjustments needed to lock in sharp focus on planetary details or faint deep-sky objects without slipping.

Like all large Newtonian reflectors, you will need to perform routine collimation to keep the optics aligned. The included collimation assist tool helps simplify this process, and once you get the hang of it, it becomes a quick, standard part of your setup routine.

At the zenith, the eyepiece sits at 167 cm (about 5.5 feet) high. If you are of average height, you will likely need a small step stool or observing chair to comfortably reach the eyepiece when viewing objects directly overhead.

The red dot finder is excellent for initial alignment and finding bright stars or planets. However, because this telescope has such a high focal length and narrow field of view, many experienced observers eventually upgrade to an optical finder scope or a Telrad for more precise star-hopping.
