Model: borg_90fl_f4_drawtube_setPart Number: 6690Brand: Borg
Japanese made Borg 90FL f/4 drawtube astrograph features a premium quality Fluorite objective from Canon with 80mm tube diameter.
The 'drawtube' package features a drawtube for easier focusing and doesn't include the M57 camera rotator found in the regular astrograph package. To use visually you can simply remove the reducer and replace with a 2" eyepiece holder available separately such as 7504.
The addition of the drawtube makes this useful for use as a telephoto lens for wildlife photograph as it allows focusing at various distances - the pure astrograph set is designed primarily for focusing at infinity.
Includes a Borg Helical focuser for precise dependable focusing.
Modular Borg design allows you to reconfigure the scope for visual observing or to disassemble it for ultra portability.
