If you're serious about astrophotography, Orion brings you a new way to assure the best tracking performance possible, even in adverse conditions.

The SteadyStar Adaptive Optics Guider (AO) makes any imaging-capable mount, even if a modest one, perform more effectively. Precise tracking is one of the most critical facets of astrophotography and this tracking is limited to the accuracy of your mount, plus external factors like wind and atmospheric seeing conditions. The SteadyStar AO Guider overcomes these limitations and challenges and takes control with super fast and accurate guiding.

Traditional autoguiding involves moving the mount and telescope, along with all of your attached imaging accessories to correct for tracking errors. Furthermore, autoguiding can typically only make a single correction every couple of seconds or so; during that time your tracking is vulnerable to periodic error from your mount, wind, and atmospheric seeing conditions.

The SteadyStar AO Guider has a better solution.

Seen below are two raw images of NGC 281 cropped at 100% zoom. They are a direct comparison of SteadyStar AO Guiding at 5 corrections per second vs. regular autoguiding at one correction every two seconds. The images were taken the same night in succession. Each image is a stack of 3 x 12 minute exposures taken with the Orion SSDSMI III and EON 120ED Refractor. The image taken without the SteadyStar AO Guider shows star elongation in R.A. as a result of periodic error.

We've illustrated a smaller cropped portion below of the same two images of NGC 281 magnified at 200%. The difference seen in this faint star field is immediate. The SteadyStar improves the tracking performance resulting in sharper stars, rounder stars and improved image contrast.

The SteadyStar AO Guider can easily make several tracking corrections in one second without lugging the weight and inertia of the whole telescope. Rather than move all that weight, the SteadyStar AO Guider moves a small on-board lens, allowing for quick and precise movements several times faster than any traditional autoguider could ever hope to correct. This refractive correction, while different than the adaptive optics used in professional observatories, is capable of making extremely fast movements to overcome even the most severe tracking errors. The SteadyStar AO Guider is capable of correcting motion more than 40 times per second, depending on guide star brightness and computer speed. This means you will overcome your mount's periodic error, wind, and even compensate for some of the negative effects of turbulent seeing conditions. Quite simply, the SteadyStar is the fastest AO Guider used for amateur astrophotography on the market today!

With the SteadyStar AO Guider attached, even a modestly priced equatorial mount will perform like a much more expensive mount! The SteadyStar's broad compatibility with imaging cameras and autoguiders makes it even more attractive. It works with any Orion CCD camera and autoguider, as well as other popular imaging cameras like DSLRs.

The SteadyStar AO Guider was designed to fit right in with your astronomers gear, requiring only 90mm of inward focus travel when used with Orion imaging cameras. In fact, you can add up to 30mm worth of accessories, such as a filter wheel, to the SteadyStar without adding to the total backfocus.

The 40mm diameter on board lens supports APS-C format sensors including DSLRs and amply sized CCD cameras. SteadyStar software is included for full guiding control to both your mount and the AO Guider, and it can communicate with MaxIm DL to enable advanced imaging features as exposure sequences and dithering. Windows XP, Vista 32/64 bit and Windows 7 compatible, ASCOM, compatible.

A hard carry case is included as well as a 10' USB cable, 10" autoguiding cable, and 12 V DC power cable.
