Ostara telescope accessories in Lincolnshire

Product Description

The Ostara 1.25" 90 degree prism diagonal is designed to give correct left / right orientation views when use with a refractor telescope.

This allows for finding objects much more quickly, than mirror 90 degree diagonals, and also makes it ideal for use of terrestrial targets when used with a suitable short tube telescope.

Plastic body. Complete with lens caps and box. Not threaded for filters
