During the past several years, apochromatic refractors (those featuring the best color correction) have become more common. Some incorporate innovative designs to meet the needs of the amateur astronomy market. One such telescope is the Stellarvue SV105–3SV. I had the opportunity to test this telescope recently after having used the original SV105 a few years ago. The main difference between the current SV105–3SV and the original instrument is that Stellarvue designed its newest scope with astroimagers in mind.
Stellarvue, based in Auburn, California, was founded in 1997 by astronomy devotee Vic Maris. Since then, the company has earned a reputation for building high-quality refracting telescopes with apertures ranging from 2.8 to 6.3 inches (70 to 160 millimeters).
