A chair with an adjustable seat height is required for comfortable and efficient visual observations through the telescope. With it, the observer can sit comfortably at the eyepiece and make long observations without feeling very tired. The Asterion LiteSeat chair is designed to do just that. The chair is designed so that the seat height can be quickly adjusted from 20-75 cm. This allows it to be used comfortably with telescopes on Dobson mounts up to 10'' or with compact telescopes on low tripods.
