Antlia modular OAG System with 2″ Mounted Filter Drawer

Antlia modular OAG System with 2″ Mounted Filter Drawer 

Description:
The Antlia OAG and 2″ filter drawer assembly offers a compact, rigid solution for deep-sky astrophotography. It combines an off-axis guider with a sliding drawer for mounted 2″ filters, saving space and improving mechanical integrity.

Its 12x12 mm prism is height-adjustable, ensuring excellent star pickup even with narrow light paths or large sensors. The integrated helical focuser provides 10 mm of precise backfocus adjustment for the guide camera.

The drawer accepts 2″ mounted filters (M48 x 0.75 thread) and features a mechanical locking screw with smooth rotation. The system includes both telescope and camera side adapters (M42/M48/M54/M60 male and female), all rotatable to ensure perfect alignment.
