The only PRACTICAL fixed point in the sky to aim at is an OBJECT like the sun or the moon. You can sign up for alerts for when the ISS will pass the sun or the moon from your location. Then, if you have the camera mounted on a clock-driven telescope (or other automatic means) you might have a chance of catching the sillouette as it passes in front of the lighted object.
But since the ISS transverses the sun or moon in about a SECOND, you won't have time to be fiddling with your tripod, even to center the sun/moon. If your camera is not on something that tracks, to account for the turning of the earth you would have to make sure that your field of view included the sun/moon at the specified minute. Then, as long as you weren't BLINKING at the wrong second, you could take rapid-fire shots and get something like this: http://pictures.ed-morana.com/ISSTransits/ I haven't tried it yet, but from a useable image standpoint, I think it would be much easier than what I tried to do last night. A sillouette is easier than a lit object. -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
