"The SynGuider's ability to guide a set-up for deep-sky imaging is excellent, and allowed us to capture the North American Nebula with fine detail. We also captured some test images of the region around Vega to compare 5-minute unguided and guided images. The improvement using the SynGuider was obvious...."The SynGuider is very different from most other autoguiding systems in that it is very much a stand-alone unit. This gives an immediate advantage over other autoguiders in that you don't need a PC or guiding software to operate it, so there is less equipment to carry around and set up.
What makes the SynGuider unique is it's built-in display screen. This not only gives access to a comprehensive set of options for controlling the camera and the guiding parameters, but it also displays the actual guide stars. Once you have chosen a suitable guide star with your own eyepiece and replaced it with the guide camera, the display immediately shows the guide star. It's a subdued white-on-red display to help maintain your night vision. The screen is divided into two zones, the left half displays the various menus and text data and the right half shows a real-time 1-bit image of the star in the field of view"...."Price has always been an issue with other stand-alone auto-guiders - you previously had to spend a similar amount to a PC and a conventional guide camera combined. But the SynGuider changes all that: what we have here is a complete system that costs less than many conventional guide cameras on their own" BBC SKY AT NIGHT MAGAZINE
