aguinaldo_de_paula 0 Posted January 30, 2009 Superb image. Could you share how do you manage to make the camera move along with the earth's rotation in order to keep the stars so sharp in a 45 mintes exposure? Best regards, Aguinaldo Link to comment
wmhoodphoto 0 Posted January 30, 2009 ...to all for your precious time and comments. Aguinaldo: The telescope mount has a motor drive that tracks the image. First, it must be precisely aligned with the Earth's axis of rotation--which usually takes about 45 minutes. Then, once the exposure is started, minute corrections must be made during the entire exposure due to periodic errors inherrent in the motors. This is done either manually thru a "guiding eyepiece", or with a CCD autoguider/imaging devise. Next to correct focus, this is the most critical step. Link to comment
