Video camera uses

Alan P Buckman

Thanks Alex and Robin for your comments. I guess I am harking back to the days of PE Photometry using PM tubes and photon counting. I was using this when I worked at the RGO at Herstmonceux for industrial training. in the late 70’s. The idea of attaching a video camera to a variety of lenses to cover fields up to about 20 degrees means I can wander round the sky and view in comfort and have the recording available for later. With the 6 magnitude dynamic range and the variable gain and integrating nature of the camera means I can see possibly down to 10th magnitude with a 200mm telephoto lens which will give splendid sights of large fainter star clusters with the possibility of measuring stellar magnitudes from the recording.
