The Astro Hutech Hinode Solar Guider is the first autoguider designed for casual solar viewing as well as photography. It does not require precise polar alignment, allowing for quick, convenient setup-and-go for public outreach or quick viewing with a grab-n-go solar scope and eliminates keeping the sun centered over a long observing session.
For imaging, long-term autoguiding on the sun simplifies post-processing for projects such as time-lapse movies.
While guiding effectiveness is dependent on the entire telescope and mount system, plus external factors such as atmospheric effects, the Hinode guider can detect position errors on the order of 1 arc second with a lab light source, and the smallest correction it will make is 100ms (programmed into firmware with typical mount electronic and mechanical limitations in mind). This corresponds to 1.5 arcseconds at 1x guide rate (correction speed at 1x sidereal drift) and .75 arcseconds at 0.5x guide rate.
The Hinode Solar Guider is supplied with an optics/electronics assembly box, hand-controller, USB cable, hand-controller cable, autoguider cable, and choice of mounting base.
