Sky-Watcher BKP 15012 EQ3-2 150/1200 Telescope

The main element of this telescope is a parabolic mirror with a diameter of 150 mm (6 inches) and a focal length of 1200 mm. The correct diameter makes it possible to use many interesting filters, the optical tube itself, as well as the mount make it possible to obtain significant magnifications.

Optical system
A mirror telescope (Newtonian system) is particularly recommended for observing the Moon and planets due to its medium brightness.

The main and important feature of the telescope is the large 150 mm parabolic mirror which determines what and how we will be able to observe.

This telescope captures about 320 times more light than the human eye at night, providing the ability to observe objects up to almost 12-13 stellar magnitudes (with naked eye visibility up to 6 stellar magnitudes). The size of the mirror is also linked to the optical resolution, which in this telescope allows the resolution of stars that are more than 0.9’ apart.

In addition, the telescope includes a Barlow lens, which in combination with a 1.25" diameter eyepiece will double magnification, but at the expense of field of view and image brightness.

Mount
The EQ3-2 is the lowest mount model, which has space for a polar scope. It is characterised by its robustness, precision, stability along with a wide range of various functions which are useful to any advanced astronomer.

The mount head rests securely on a sturdy, adjustable aluminium tripod equipped with a useful storage shelf. Precise micro-movement knobs allow accurate manual tracking of objects in the sky. The mechanics of the EQ3-2 mount are built around special gear- screws, allowing precise control of movement in both the rectascension and declination axes. The mount can be operated with single or dual axis or it can be converted to a full axis mount - GoTo system.

Extractor
The telescope is equipped with a 2-inch eyepiece focuser with reduction to 1.25 inches. Two eyepieces are included: 25 mm and 10 mm.

Included are:
- Super 10 mm, 1.25’ eyepiece (120x),
- Super 25 mm, 1.25’ eyepiece (48 times),
- 2x Barlow lens with T2 adapter,
- 6x30 viewfinder.
