Description

Choose a flexible foundation for custom telescope building with the Bresser N 150/750 Messier Hexafoc Reflector OTA, a standalone 150 mm Newtonian optical tube with a 750 mm focal length and listed f/5 optical ratio. The tube combines a 2.5-inch Hexafoc focuser, 6×30 finder, 26 mm eyepiece, heavy-duty rings, carrying handle, integrated camera holder, stainless steel rail, and adapter hardware for compatible mounting systems.

The verified OTA configuration includes a parabolic primary mirror, aperture solar filter, smartphone navigation adapter, Stellarium software, 2-inch eyepiece adapter, integrated 1.25-inch and T2 adapter, universal dovetail connection, and camera mounting features. The mount, tripod, tracking equipment, counterweights, GoTo controller, and power system are excluded from the standalone optical tube and must be selected separately for the final telescope configuration.

Key Features of Bresser N 150/750 Messier Hexafoc Reflector OTA
