Hi complete newbie to VPHOT - trying to get some images uploaded to do some testing.

I have the following error which I dont understand - any help appreciated.

STEP 1: TELESCOPE
STEP 2: TEST IMAGE
STEP 3: REVIEW HEADER
STEP 4: UPLOAD IMAGES
STEP 5: SUMMARY

 

UPLOAD:
The image was successfully uploaded

PROCESSING:
The image was successfully un-zipped, and FITS header read

FITS HEADER:
 

 

Invalid or missing exposure time (EXPTIME or EXPOSURE). Can not continue.

Please return to the previous step and upload another file

 

 

The loaded header shows EXPTIME in loaded!?

Fits Headers

Hi Keith:

Edit: What kind of camera/image was this "DSLR? Was TG filter debayered and TG saved as fits file?

VPhot "requires" certain fits headers to work properly. AIJ does not provide them all.  ;-(

So, you need to add them:

1. By hand edit (bad)

2. By using something like maxim ($) or "F2W2HDU (header software- look it up)

3. Use upload wizard (not quick upload) in VPhot and fill in needed info.

Despite what it says, were all the required headers present?

Since you stated that "exptime" was there, send me one of the images attached to an email to kenmenstar@gmail.com. I'll take a look too.
