Meade #825 8x25mm Right Angle Viewfinder, for ETX-90EC & ETX-90RA Telescopes

#825 8 x 25mm Right-Angle Viewfinder: Similar in optical characteristics to the 8 x 21mm straight-through viewfinder supplied as standard-equipment with the ETX-90EC, the #825 right-angle viewfinder allows for a comfortable 90° viewing position. The #825 viewfinder replaces the standard-equipment 8 x 21mm viewfinder and fits into the same bracket on the telescope.
