I had qty 2 good WCS and CAL images that when stacked in VPhot had the CAL go to red. When viewed, the resulting stacked image just showed white. This is the 1st I've seen that. What's the cause?

Peter:
Even though they both show as green for WCS and Cal, what do both original images actually look like when you open them individually? Is one of them visually unusual in any way? Share them to MZK.

Look at a0139 and a0140 in http://aavsonet.aavso.org/bsm_nm/bsm_nm_210404_images/index1.html
