We are getting close to the 2.0.0 stable release and the full manual. The manual will soon become available on the website and also in PDF format. Both versions will be identical and once released, will start to follow the APP release cycle and thus will stay up-to-date to the latest APP version.

I seem to be having this dialog box throw up when trying to perform flats calibration with Master Dark Flats loaded. The same issue does not occur if I specify a Master BIAS though, so I am wondering if it is taking into account the Master Dark Flats. I create two sets of master flats, one that has been MDF corrected and the other that has been BIAS corrected.

As you can see my Flat frames have the same exposure, gain etc as my MDF:

Just not sure why it is complaining and wanting to know if the MDF is being applied to the flats

Regards

Simon

Found the issue, when I loaded the original Dark Flats, for some reason they were loaded in as Darks, so it made them MD's as opposed to MDF's, might have been user error or a glitch in the Matrix

I do have a follow on issue though

When adding the Dark Flats with their appropriate filter, if you choose Hydrogen-alpha, Oxygen-III it might not map the MDF to your flat frams if you camera saves them as Ha and OIII, it throws the same message. This is because the Filter Tag in the FITS Header do not match.

You have to make sure you choose the right one
