WBPP - LN Reference Generation failing

[veames]

When I run WPBB on my latest 100 subs I am getting error:

"Error: Unable to compute a valid scale estimate (channel 2)"

And LN Reference generation is failing, I have used this several times before and never had this error. NOTE: I did make the registry change for long filenames.

This is a ZS73 Scope with a L-Pro filter and OSC Camera.

Usually the issue is before LN.
Typically the calibration is bad or there is oversubtraction due to lack of a pedestal.
Did you check your calibrated data? Are there zeros?

Thanks! I am very new to astrophotography, how can I verify the calibrated data/zeros?

You can use the Statistics process. With "Unclipped" not checked, you should have 99.999%+ of your pixels with a mean above zero. You can also mouse over the image with your left button down and see pixel values. The dark areas should be well above zero.
