All Sky ST-237AS CCD Camera ##IN STOCK##
Many observatories use an all sky camera to monitor changing sky and weather conditions. Until now, obtaining high quality 180 degree views of the sky required an expensive large format CCD and a similarly expensive fish eye camera lens. Now the ALL SKY cameras make this possible for much less. The lens used in the ALL SKY cameras is a high quality custom mounted 1.24mm F/2.8 fisheye. In order to illuminate the TC-237 CCD with the full field of the fish eye, the rear of the lens must be mounted very close to the CCD. To place the lens at the correct distance, a special housing has been designed that replaces the CCD chamber. The shutter or filter wheel must be removed and a new face plate will be made to cover the front of the camera head. The face plate will have provisions for a cap that may be used to take dark frames and for protection when the camera head is not in use.
