WCS failure

[stevesmith]

I've posted this before but haven't got a solution.

We're doing photometry on a bright star in a sparse field.  The brightness forces short exposures, which result in other field stars being faint.  AIJ's WCS routine isn't able to plate-solve.

Would appreciate any help

Hi Steve,

You'll obviously need multiple star detections in the image for a successful plate solve. Watch for the light blue circles that get placed around stars in the image when the plate-solve is running. If only one or a few stars are being circled and there are other detectable stars, you may need to reduce your noise tolerance setting. Here is a set-up that usually works for my images:

Hi Karen:

Thanks, yes, that worked very well.  Astrometry solutions are working...
