Explore Scientific Achromatic Refractors

Explore Scientific achromatic refractors use two-element doublet objectives, a simple and robust design for visual observing. The range runs from the Galileoscope STEM kit and FirstLight 80mm to the Sidara Nano 90, Sidara Essential, Sidara Pro and Sidara Plus models, up to the AR102, AR127 and AR152 doublet tubes.

Smaller kits suit beginners and families, while the larger AR tubes give wide, bright views of star fields, the Moon and brighter deep-sky objects at low power.
