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.

Suitable for

• Visual observation of the Moon and planets
• Wide-field and medium-field views of star clusters and nebulae
• Beginner to intermediate astrophotography with simple guiding
• Educational use and hands-on astronomy sessions

Key specifications

• Aperture: 150 mm
• Focal length: 750 mm
• Optical type: Refractor
• Mount type: Equatorial mount (EQ3-2)
• Intended use: Visual observation and basic astrophotography

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.

Usage 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.
