As a matter of fact the ONAG allows for ON, as well as OFF axis, operations presenting you scope FOV to your guider. ![]() The ONAG has an integrated X/Y stage for your guider which provides a wide field of view (FOV) for selecting the guide star. The ONAG’s DBS reflects the visible light from the telescope to the imaging camera and passes the near infrared (NIR) light, which is usually useless for imaging purposes anyway, to the guiding camera for auto-guiding. Our ONAG has a special dichroic beam splitter (DBS) which is also known as “cold” mirror inside of it. The ONAG uses a new, innovative and unique, patent pending technology from Innovations Foresight. (Dennis di Cicco, Sky & Telescope December 2012, pages 60-63) Click here to read the full Sky & Telescope magazine ONAG field test review The device,…, is extremely well engineered and, more importantly, well made.” “A clever as the concept behind the ONAG® is, the devil is on the details, and that’s where the ONAG® really shines. “The guiding was remarkably accurate during all my testing”. “…Ingenious!” And it works because digital technology has given us the opportunity to easily use NIR light for guiding.” Because digital detectors in today’s autoguiders are sensitive to near-infrared (NIR) light beyond the visual spectrum, the ONAG® works by sending a telescope’s visible light to the imager camera and the NIR to the guider system…” It’s a need that arises from a very long list of mechanical, optical, and atmospheric factors that makes it all but impossible for a simple telescope drive to precisely follows a celestial object for more than a minute or two as it moves across the sky.” “Observers, have been guiding their telescopes since the dawn of long-exposure astrophotography.
