VPHOT not recognizing WCS from T21

Mon, 11/19/2018 - 21:51

Hello all - first time poster here, but I don't think this question is overly naive.

When I upload my images to VPHOT, the WCS is not recognized. The WCS exists - Astroimagej has no trouble telling me where my pointer is, and I've verified (at least by eye) that the WCS is correct. 

The images were taken with the T21 telescope at iTelescope, although I didn't send them directly to the sever, I downloaded them and uploaded them to VPHOT.

Anyone have any thoughts why VPHOT isn't recognizing the WCS?

Please share this image with SGEO.

Must be some issue with the FITS header keywords.



Fixed - but I'll share the image for reference

I fixed it by uploading the image to astrometry.net, and then resubmitting to VPHOT. So it's probably some bad FITS keywords from T21, which isn't great.

If I can figure out how to share the fits file with you, I will.

To share, on your image list, click the box to the left of one of the images and then click the "share" link at the top. Then place "SGEO, MZK" in the next box. This will share the image with George and I.

Did you select the plate solve checkbox for your plan in iTelescope? I assume so?  Or did you use AIJ to plate solve the images you downloaded from iTelescope?

There should be lots of TR and CR headers in the fits header?
