Pegasus Astro Indigo Off-Axis Guider Premium

with Helical Focuser

• Precision Guiding for Astrophotography: The Pegasus Astro Indigo Off-Axis Guider Premium uses the same optical path as your primary imaging camera, helping eliminate differential flexure commonly associated with a separate guide scope and supporting more accurate long-exposure guiding.
• Pre-Installed Helical Focuser: The Premium version includes a helical focuser for smooth, precise guide-camera focusing and convenient compatibility with commonly available 1.25-inch guiding cameras.
• Ultra-Thin Imaging Train Design: With a body thickness of just 10mm, plus 4mm for the telescope adapter, the Indigo OAG requires only 14mm of total back focus, making it ideal for space-conscious astrophotography imaging trains.
• Lightweight CNC Aluminum Construction: Precision CNC-machined from aircraft-grade 6061 aluminum alloy, the Indigo OAG delivers excellent structural rigidity while keeping overall weight low enough for demanding telescope setups.
• Adjustable Pick-Off Prism: The prism height can be easily adjusted to optimize illumination of the guiding camera. For systems using larger imaging sensors, the prism can be moved upward and secured with set screws to prevent obstruction of the main camera's optical path.
• Large Multicoated Guide Mirror: A generous 12 x 8mm fully multicoated, anti-reflection mirror provides excellent light transmission to the guiding camera, helping deliver bright, round guide stars across the OAG field.
• Large 53.5mm Clear Aperture: The wide optical opening accommodates modern astrophotography systems while helping minimize unwanted restriction in the primary imaging path.
• Modern CMOS Camera Compatibility: Integrated M2 and M3 through holes provide flexible direct-mounting options for compatible modern CMOS astronomy cameras, filter wheels, and other imaging equipment.
• 62mm Through-Hole Pattern Support: The Indigo OAG supports a 62mm through-hole mounting pattern for convenient direct connection to compatible CMOS cameras and filter wheels.
• Direct Indigo Filter Wheel Integration: Designed to pair seamlessly with the Pegasus Astro Indigo Filter Wheel, creating a compact and rigid imaging system with a combined back-focus optical distance of approximately 33mm.
• Adjustable Image Train Orientation: Three mounting screws allow the telescope adapter to slide within dedicated slots, making it easier to rotate and fine-tune the framing orientation of your imaging train.
• Built for Heavy Imaging Equipment: Despite its slim profile, the solid construction is engineered to securely support substantial astrophotography equipment without sacrificing stability.
• Upgradeable Design: Existing Indigo OAG owners can add the optional Pegasus Astro PEG-INDIGO-OAGHF Helical Focuser separately for enhanced focusing precision.
