Product Description

The Stellarvue 90 mm apo triplets come in either a durable aluminum tube or the lightweight carbon fiber tube. The 90 mm f-7 apo triplet lens is made with FPL-53 optical glass. It’s light weight allows it to be mounted on smaller mounts and makes it an excellent travel or guide scope.
