WORDS: TIM JARDINE
The Altair 70EDT-F is a travel-friendly refractor with premium optics, offering the choice between grab-and-go visual observing and astrophotography. Our review telescope came as a package, including a 0.8x reducer/flattener lens which corrects for inherent coma and takes the 70mm diamater lens from an f/16 to an f/4.8 and a working focal length of 335mm. This means that when it’s combined with a DSLR or a dedicated astro camera, the 70EDT-F can present images with a field of view that’s easily wide enough for a large nebula such as the Orion Nebula, M42, or extended star clusters like the Pleiades, M45.
