The fast f/8 Advanced Coma Free optical system produces a wider, flatter field with no coma for pinpoint stars out to the edge of larger imaging sensors and extreme wide angle eyepieces.
Buckle up, because this is one fast astrograph! Its prodigious light grasp (200mm aperture) and zippy f/4 focal ratio combine to capture tremendous detail and light with short exposures from DSLR or dedicated astro cameras. Super affordable, too!
With its big 10" aperture and 1000mm focal length, this fast f/4 astrophotographic powerhouse will take your imaging to an exciting new level. And it's way more affordable than premium "apo" refractors with just a fraction of its aperture.
The EON 70mm ED Quadruplet Astrograph Refractor Telescope features 350mm f/5 focal length, Hoya FCD-100 ED glass, a 43mm image circle, and a robust 10:1 reduction focuser. Produces stunning wide field photographs in a very compact package!
