Explore Scientific AR102 102mm f6.5 Air-Spaced Doublet

MPN: 0114102

Price: 517.00

The Explore Scientific AR102 102 mm f/6.5 Air-Spaced Doublet is an excellent choice for those looking for a rich field refractor telescope, with a superbly engineered focuser and lens cell. Explore Scientific have rightly gained a good reputation for delivering high quality instruments at reasonable prices. While this telescope is an Achromat and doesn't have quite the colour correction of Explore Scientific's Triplet series of Apochromatic ED refractors, the general optical quality is first rate as an Achromatic design making this an affordable alternative.
