I have an image of the Rosette nebula that astrobin was able to platesolve without problems, but PI won't for some reason. I am not getting enough star pair matches. Clearly I am doing something wrong here. Have any of you experienced this with the plate solve system in PI? I was hoping to apply some photmetric color calibration to my image.
One thing I did notice is that when I acquire the focal length and pixel size from the image they appear to be incorrect. I am imaging at 510mm (Orion 80ED with 0.85 FR) and use a Canon 500D which has a pixel size of 4.7 microns from my understanding. PI reports the focal length at 996 mm and a pixel size of 9. I have tried it with PI's values and values I enter directly with the same result.
I have used the tool in PI to set the coordinates on NGC2244 and those look correct.
I am sure that I must be missing something simple here - any hints?
