Robert,
The photos were taken from the North East corner of Lake Massapoag at 42d 06’39” N, 71d 10’ 35”. Your result of 42.0477 N, 71.1326 W lies 4.25nm in a direction roughly towards the rocket. Well done! My own calculation yielded 42.0346 N, 71.1172 W which is about a 1nm further out than yours but along the same direction. The difference between the true and computed positions translates into around a 10’ error in declination so perhaps with a bit more care in the measurements one might be able to do better,
Regards,
Robin Stuart
