To make use of that you need to know the image center and FOV to work out "d".
eg APS-C long axis 23.3mm. At 11mm -> 93° FOV so pointed at dec -45 with that axis aligned n/s some stars are on the equator.

Andrew,
Yes that's right. That's why I say declination of the stars in the field closest to the equator rather than dec of the stars at the center of the field of view.
