70 mm refractor for beginners
The Celestron AstroMaster LT 70AZ is a 70 mm diameter refractor telescope with a 700 mm focal length and f/10 ratio. It uses an altazimuth mount for simple up-down and left-right motion. The package includes a built-on StarPointer finderscope, two 1.25 inch eyepieces and a 1.25 inch star diagonal. It is aimed at new users who want a straightforward introduction to visual astronomy.
Passive optical system
The telescope has no motorised drive, cooling fans or electronic components that draw power. Thermal behaviour is limited to the glass reaching ambient temperature naturally. Noise is absent because there are no moving mechanical parts during observation. The adjustable steel tripod provides a stable platform without vibration from internal sources.
Software and accessories for first sessions
The Sky X First Light Edition astronomy software supplies sky maps and planning tools for indoor preparation. The 20 mm eyepiece yields 35x magnification and the 10 mm eyepiece yields 70x magnification for different target sizes. The StarPointer finderscope helps centre objects before switching to the main eyepieces. The accessory tray on the tripod keeps the supplied items organised during use.

Questions about this item
How do I attach the 1.25 star diagonal and eyepieces to the 70mm refractor?
Insert the star diagonal into the focuser drawtube, secure it with the locking screw, then slide the 20mm or 10mm eyepiece into the diagonal and tighten its thumbscrew; the step most people miss is fully seating the diagonal before locking it, otherwise the image shifts when the tube moves.
What parts of the 700mm focal length telescope will need replacement after regular observing sessions?
The 1.25 eyepieces and star diagonal may eventually show coating wear or loose barrels; the StarPointer finderscope battery will need changing when the red dot dims; the altazimuth mount’s tension knobs can loosen over time and should be checked periodically.
At what point does the adjustable steel tripod become the limiting factor during long viewing periods?
Vibration from the lightweight single-leg tripod usually appears first — any breeze or touch transfers shake to the 70mm refractor, making high-power views with the 10mm eyepiece unsteady before optical limits are reached.
