Hello all,
I took two pics of (1075) Helina the other night. I do the Astrometry on the first pic OK quite a few stars used and positions all good - but the second pic I took about half an hour later simply doesn't work. The pic is 49 x 33 mins and is only a few minutes out of alignment with the first pic, and I enter the appropriate centre coordinates. The message comes up saying only 2 stars were identified and when I opt for manual alignment the overlaid object circles are not even remotely like the star positions in the pic. Yet is it a virtual clone of the first!
Can anyone help me?
Richard
