BTA TV grabbers & Webcams

Comments::   It is NOT a "live" camera! Here you can see copies of grabbed TV-frames from host sky.sao.ru or n2.sao.ru. The grabber card is of BT848/878 type with two TV inputs.
  Hight-sensitive observational TV-cameras from BTA focuses are connected to this input channels. When observers utilize grabbed frames (e.g. accumulate them or start autoguiding tool), the special program (originated from webcam) convert every resulting image to JPEG format and copy it to Web-site.
  So you can see changes only during observation night and only in one channel. At daytime you ordinary see the last image of the last night.
