Airy Disk APO 96mm f/6 ED Apochromatic Refractor

A compact ED for powerful images. A 96mm aperture offers visual observers excellent optics and high-quality mechanics. An almost 4-inch aperture with good resolution paired with the 0.92x two lens focal reducer gives astrophotographers a great quad imaging scope for Full Frame photography. Thanks to the high-quality doublet lens system, this telescope is high value proposition. Corrected in green and no slouch in red. Its got amazing performance for a double lens system. One reason for this is the Hoya ED glass FCD1 made in Japan with its exceptionally low dispersion.
