Starwave ASCENT 102 ED Triplet APO Refractor

A 102mm Triplet refractor offering APO level colour correction for superb views, and images of the night sky, as well as astrophotography at F5.6 or F7 with accessories.

Altair Astro continues to set the standard when it comes to optical quality control and value for money. Every lens cell has a QC serial number and is guaranteed to arrive in perfect collimation for razor sharp Lunar, planetary, and star images - without colour aberration, even at high powers. Satrurn's rings and the Cassini division, as well as the Great Red Spot on Jupiter, festoons and ovals, pop out easily thanks to the high contrast and well figured and tested optics. With a wide field eyepiece, starfield views are simply stunning, with that "diamonds on black velvet" effect that only a good refractor can produce.

Astrophotography is especially rewarding with the Starwave ASCENT 102 Triplet APO, with star colours rendering as true as possible, thanks to the triplet lens colour correction.

Two focal lengths for astrophotography: Your choice of a separate M63 reducer or field flattener can be used with the ASCENT 102 Triplet APO.
