Pegasus Indigo OAG Premium
Visit Pegasus Indigo OAG Premiumequipped with an integrated helical focuser, is a top-of-the-range solution for astrophotography, combining ultra-thin design, exceptional optical precision and advanced features. Designed to meet the requirements of the most ambitious astrophotographers, this tool optimizes guidance while reducing mechanical stress.
Design and materials
Made from CNC-machined 6061 aerospace aluminum, the Indigo OAG Premium is both lightweight and robust. Its overall thickness remains incredibly thin, with just 14 mm of optical draft (10 mm for the OAG + 4 mm for the adapter). This compact design allows easy integration into complex configurations, without compromising stability or performance.
Integrated helical focuser
The helical focuser included in this premium version offers precise focus control for 1.25" format guide cameras. Thanks to its smooth, backlash-free mechanism, it enables precise adjustment of the guiding camera's focus, guaranteeing sharp, well-defined stars. This focuser is also compatible with a wide range of modern CMOS cameras.
Adjustable prism and wide field of view
- 12 × 8 mm prism This multi-layer prism with anti-reflective coating guarantees optimum light transmission. Stars appear round and bright across the entire surface of the guiding sensor.
- Prism adjustability The prism can be moved vertically to avoid vignetting on large imaging sensors. This flexibility optimizes the illumination of the main camera's field of view.
Universal compatibility
The Indigo OAG Premium is designed to adapt to a wide variety of equipment thanks to its many connection options:
- Telescope side M54x0.75 or M48x0.75 threads.
- Camera side M54x0.75 or M48x0.75 threads.
- Guidance camera Standard 1.25" connection.
- Through holes (M2/M3) for direct attachment to modern filter wheels or CMOS cameras.
Outstanding optical performance
With a clear 53.5 mm aperture, the Indigo OAG Premium supports full-format sensors without shading or vignetting. This makes it an ideal choice for configurations using large-format imaging cameras.
Practical applications
- Long exposure astrophotography Perfect for capturing deep-sky objects with precise tracking.
- Compact configurations Its ultra-thin design reduces overall weight and simplifies complex optical systems.
- Reducing differential bending By using the same optical path as the main camera, it eliminates mechanical errors due to offsets.
Box contents
- Indigo OAG Premium optical divider with pre-installed helical focuser.
- M54 (4 mm) threaded adapter for telescope connection.
- M48 (4 mm) threaded adapter for camera connection.
