Refracting telescope Skywatcher BKP 15075 EQ3-2 — 150 mm aperture, 750 mm focal length

The Skywatcher BKP 15075 EQ3-2 is a refracting telescope with a 150 mm aperture and a 750 mm focal length on an EQ3-2 equatorial mount. It is designed for visual observation and basic astrophotography, offering bright, contrasted images of the Moon, planets and many deep-sky objects. The optical configuration and focal ratio provide a balance between wide-field views and sufficient magnification for planetary detail, while the included EQ3-2 mount allows for manual polar alignment and tracking to support longer observation sessions and simple guided imaging.

Advantages

The instrument combines a large 150 mm aperture with a moderate 750 mm focal length to deliver increased light-gathering capability and a practical focal ratio for a range of targets. The EQ3-2 equatorial mount supports polar alignment and manual tracking, improving stability and enabling extended visual observing and basic astrophotography. The refractor design typically requires little maintenance and provides high-contrast views suitable for both planetary and many deep-sky objects.

How to use

Set the telescope on a stable tripod and perform polar alignment of the EQ3-2 equatorial mount following the mount's alignment markings and instructions. Start observations with a low-power eyepiece to locate targets, then switch to higher magnification eyepieces for detail on the Moon and planets. For basic astrophotography, use the mount's tracking capability after polar alignment; attach a camera or guide scope according to the camera and mount adapter instructions. Balance and tension adjustments on the mount should be checked before longer sessions.

Recommendations

Use the telescope from a dark location and allow the optics to reach thermal equilibrium before high-magnification observing. For astrophotography, ensure accurate polar alignment and consider using short exposures or simple guiding to reduce star trailing when using the EQ3-2 mount.
