Hi guys,
I've been having trouble with this problem and would appreciate just some direction to assist me.
I have to estimate the motion of Pluto in "/hour from observations given that the telescope is a 14inch f/11 with an AP7 CCD camera with pixels 24microns on a side.
Now we have two pictures of Pluto at epochs separated by a little more than half an hour. I assume that since the resolution of the camera is given you'd have to measure something on the picture. The other though I had was that you would need to find the image scale of the telescope (which I've done).
Image scale = [tex]d\theta/ds[/tex] = [tex]206265/F[/tex] = 52.7" per mm.
Where F is the focal length determined by the formula f=F/D.
I swear I have to use the image scale of the telescope and the resolution of the camera together to get any further in this problem, but like I said I don't really have a clue.
Thanks for any help you might be able to give
