iOptron 70mm Refractor for Beginners

The iOptron iExplore 70AZ is a 70mm achromatic refractor telescope built on a simple AltAzimuth mount. Its 700mm focal length at f/10 delivers bright views of the Moon, planets and brighter deep-sky objects. The package includes a steel tripod and a 90-degree mirror diagonal for comfortable angled viewing. Setup is designed to take under ten minutes, making it approachable for first-time observers.

70mm Aperture with 35X to 175X Range

Three supplied eyepieces (20mm, 12.5mm, 4mm) provide 35X, 56X and 175X magnification, while a 3X Barlow lens can extend the reach further. The 70mm fully coated objective gathers enough light for lunar detail and planetary disks, but faint nebulae and galaxies will remain difficult. The rack-and-pinion focuser accepts standard 1.25" accessories for smooth, precise focusing adjustments during observation sessions.

Included Eyepieces, Barlow and Tripod

The 20mm, 12.5mm and 4mm eyepieces cover low, medium and high power without extra purchases. A 3X Barlow lens effectively triples the magnification of each eyepiece for closer planetary inspection. The 90-degree diagonal accepts 1.25" barrels and provides an upright, comfortable viewing angle. A sturdy steel tripod supplies a stable platform that reduces vibration during high-power use.

Questions about this item

Will my existing 1.25" eyepieces work with the iOptron iExplore 70AZ refractor?

Yes, the rack-and-pinion focuser and 90-degree mirror diagonal both accept standard 1.25" eyepieces, so your current accessories will fit directly.

How can I verify the telescope is correctly collimated and focused after first assembly?

Point at a bright star; a sharp, symmetric Airy disc with minimal colour fringing at 175X confirms the 70mm achromatic lens is well collimated and the focuser is tracking smoothly.

Which eyepieces and accessories ship in the box, and what must I purchase separately?

The package includes 4mm, 12.5mm and 20mm eyepieces, a 3X Barlow lens, a 90-degree 1.25" diagonal, a steel tripod and an instruction manual; any additional 1.25" eyepieces or filters are optional extras.
