• Improve your view of nebulae with your Celestron Origin, especially from urban and suburban skies. This filter blocks light pollution, increases image contrast and darkens the sky background for sharper, more contrasted images.
• This filter transmits only the key Hα-Hβ-OIII wavelengths from emission nebulae, making their colors stand out from the dark background. It also blocks light pollution, allowing it to be used even from urban and suburban skies.
• Made for the Origin 6" RASA lens. Unlike similar filters with narrower bandwidths, this filter was specifically designed to work with the Origin's fast f/2.2 lens.
• Made of Schott glass with anti-reflective coatings, the surfaces of this filter are completely flat and free of defects.

Cable compatible with Skywatcher mount with screw connection for ASIAIR PRO ZWO and power HUB - Length 100cm

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.
