some limitations to the duration of video and the amount of frames you can acquire. Resolution and file size can both limit the length of your video. Since RegiStax combines as many sharp frames as possible to achieve one highquality image, you don't want to take too many images that you start to detect the rotation of the planet, especially on Jupiter which makes one complete rotation in under 10 hours! Even one frame of a high-resolution video can use a large amount of disk space. Hundreds or thousands of frames will quickly consume much of a hard disk. We recommend storing your large video files on removable media, such as an external hard drive or DVD. SOLAR IMAGING Skyris cameras work well with solar telescopes or telescopes equipped with solar filters, including Hydrogen-Alpha or white-light filters. AUTOGUIDING Your Skyris can be utilized as an autoguiding camera when used in junction with an off-axis guider or piggyback guidescope. Skyris is compatible with many autoguiding software programs such as MetaGuide (www.astrogeeks.com/Bliss/MetaGuide), and PHD Guiding (www.stark-labs.com/phdguiding.html) using a guider port interface such as GPUSB from Shoestring Astronomy (www.store.shoestringastronomy.com). Celestron mounts can be used without a GPUSB, simply by interfacing the PC to the hand controller and connecting to the mount via ASCOM. An RS-232 to USB adapter and serial cable is required. C-MOUNT LENSES Skyris cameras can be used with an optional C-mount lens (not included). The threaded ring on the camera body provides C-mount distancing at 17.5mm. 14
