Hmm, I don't know, with 19 detected stars, it should be fairly easy to solve. By eye, I don't recognize how your image aligns with the DSS image -- is it rotated?
I also see that the image you submitted has some strange histogram stretch or something applied to it. Can you submit the original? Weird stretches usually make it difficult to correctly detect stars in the image (it's hard to estimate the noise level and rank stars by brightness).
What instrument / telescope / camera did your image come from? Are the pixels square? Are the 19 detected sources in your image actually stars, or are there some cosmic rays also?
