Hi All,

I am trying to use VPhot to analyze a .FIT file of NG7990.

When I use GCVS to identify the variables in the field it mis- identifies them.

Can someone help?

I have attached some screenshots of what I did.

Thanks

The problem is with the WCS solution. I took the liberty of downloading your image, running it through Astrometry.net and re uploading. Now VPhot can now pick out the stars.

I shared the new image back to you.
