PCC appears to be doing a full plate solve, but ends with "Insufficient Photometric Data: Got 0 samples..."

Hi
Without knowing more about your image, it is difficult to say. Is it a wide field of view? Small FOV? Deep? NB...etc etc. (In focus??)
All of that being said, the first parameter to adjust as a blind guess is under Photometry. Uncheck the automatic magnitude limit and try something like 12 or 13th magnitude.

Target is a tile field around NGC1909 (Witch Head). FOV is 106'x140'. Filters are LRGB. Focus is best I could get with @focus3 on a Cyan night per ClearSky chart. All tiles have been ImageSolved. Scope is an NP101is with .8x FL reducer. FL= 435mm. Pixel size is 3.8mm.
Should have added that PCC works with some of my images.
Follow up: Turning off the Automatic Magnitude limits and setting Magnitude to 13 got my image to calibrate. Tried another problem image and that worked also. Does this mean the problem's fixed?

Yes, this is a good solution for the issue you presented. You want to match the catalog faint threshold with something commensurate with your data so there is a good correspondence between the two of them. Does this mean I made a good guess? I am "Seldom" correct. I had to do it... it was there...

And I seldom get useable answers to my questions... So far the PI forum is batting way better than Cloudy Nights.
