The TS Superflat GPU coma corrector is one of the best correctors for astrophotography through fast Newtonians.

• 4-element coma corrector for excellent imaging in the field and on the axis.
• Designed by Gyulai Pal in Hungary (GPU-Optics)
• Perfectly suitable for Newtonian telescopes with focal ratios of f/4 - provides very good results from f/3.5 to f/6.
• Very tolerant against tilting.
• Focal length is not changed.
• Camera connection through M48 thread.
• For better stability and accuracs, the corrector can be screwed to the focuser. Connection adapters for cameras and focusers are available.

• Coma Corrector for Newton telescopes, that neither does reduce the focal length nor the image field of your telescope
• 46 mm clear lens diameter in M48 mode – enables exposures free from vignetting
• designed for fast f-ratios up to f / 3.5. Maximum sharpness across the entire image field
• Phantom Coating™ Group, multicoated for maximum transmission and total freedom from reflections

Allows a more reliable wired connection between any Skywatcher Synscan Go-To mount and a PC and certain Android devices. The dongle plugs into the mount’s hand control port and connects to a computer with a USB cable (not supplied). Users can then control a Skywatcher Go-To telescope from a computer by using either the SynScan Pro application for Windows or third party applications like EQMOD and K-Star. The dongle is supplied with cables that support both alt-azimuth and equatorial Synscan Go-To mounts (except the EQ6 Pro when the mount’s handset cable should be used instead). The dongle can also be used for updating the mount's motor firmware.

* USB cable is not included

Note: Sky-Watcher mounts which have a built-in USB port do not require this dongle.
