Features of the Celestron AstroMaster 130 EQ

  • 5.1 inches /130 mm large aperture
  • 25 inches / 650 mm focal length
  • Focal ratio F/5
  • Resolution 0.88 arcseconds
  • Limiting Stellar Magnitude 13
  • Parabolic main mirror and secondary mirrors fully adjustable.
  • 2 Eyepieces, 20mm 33x and 10mm 65x
  • Red dot viewfinder
  • Equatorial mount CG-3

The Celestron 31045 AstroMaster 130 EQ has a primary mirror diameter of  5.1 inches or 130 mm and a focal length of 25 inches/650mm. The fast focal ratio of 5 is just right for viewing faint deep space objects and stars of up to about 13 magnitudes.  The reflector telescope has a resolution of about 1 arcsecond, it provides details viewing Saturn’s rings as well as popular double star systems.

The two included eyepieces with f 20mm and f 10mm provide a magnification power of 33x respective 65x power.  Even though the manufacturer’s specs suggest a highest useful magnification of 260x maximum, this power only theoretical because of atmospheric disturbances. But getting extra eyepieces at around a 6.5mm and a 4.5 mm to push magnification to 100x  and 150x power may be useful at times to view some objects in more detail.

The telescope has a Star Pointer attached to the main tube, it projects a red dot into the field of view and makes it easy to find interesting objects in the night sky. The pack also comes with a Software ” The Sky” Level 1,  which includes sky maps, images, and data of over 10,000 interesting objects.

Celestron’s CG-3 Equatorial Mount

The AstroMaster 130 EQ mounts onto Celestron CG-3 equatorial mount. The fully height-adjustable and pre-assembled tripod is stable and provides low vibration support to the telescope. Accessories can be kept within easy reach of the accessory tray.

The hour axis of this equatorial mount is to be aligned with celestial north, (parallel to the Earth’s axis of rotation) so it is easy to follow objects in the sky with the fine adjustment of just one axle. Precise hands-free tracking is available with the optional motor drive, making the whole instrument also suitable for the beginning astrophotographer.

Advantages

Disadvantages

  • focal length limits magnification
  • not really suitable for astrophotography
