- Record astronomical events with the Watec 910HX/RC CCIR video camera
- Record the time, provided by an internal GPS system, with the IOTA VTI Video Time Inserter
- Mount the Watec to your telescope with the included C-mount to 1.25-inch adapter
- Power the camera and the VTI with two 12V 3A power supplies
- Connect the camera to your PC's USB2 port with the USB2 Video Grabber
- You will also receive a 5 m BNC video cable, BNC/RCA adapters, and an aluminum carry case.
About the Watec 910HX-RC CCIR Video Camera
Watec added a remote control unit to their WAT-910HX super low sensitivity monochrome camera, making it even easier (and more fun!) to guide, calculate astronomical event timing and occultations, or when you want to build an electronic finder. The remote control allows you to access the entire on screen display (OSD) by using the mini control paddle.
The Watec 910HX-RC camera is designed to make adjustments based on your lighting conditions via frame loss compensation, and uses integrated frame technology to achieve a low sensitivity of 0.000005LUX. Pre-calibration can be accomplished by the user to ensure the highest quality results.

About the IOTA Video Time Inserter (CCIR)
The Video Time Inserter was developed for members of the International Occultation Timing Association. It works well for any video timing application, but since it was built specifically for the IOTA, the features of the VTI are especially suited for those who wish to video record occultations. Please note that this model of the VTI is compatible with European video format (CCIR/PAL, at 25 frames per second) cameras, such as the Watec 910HX-RC included in this occultation kit.
It is fast and easy to set up the VTI. All you need are three cables, which are included in the kit. The Video Time Inserter is very accurate, since it gets its information via GPS. It may take a few minutes to acquire a GPS signal at first, but it should take less time in subsequent sessions. There are three indicator lights on the unit that display its status. If you want to attach the VTI unit to a tripod, there is a 1/4-20 threaded hole in the base.
