Starry Sky Stacker and flats

[langman78]

Hi all.

I just purchased Starry Star Stacker formy Mac.
Seems like a more than capable program and pretty quick also.
I came across this tutorial today as I’m yet to introduce calibration frames.

https://sites.google.com/view/stacking-apps/preparing-master-flat-frames

The program itself only allows light, dark and flat frames to be loaded. (Fine by me keeping it simple and I’m not after cutting edge results due to limited and basic equipment).
Wondering if any users or experienced photographers could shed some light on what the author of the tutorial means by adding dark frames to go with the flat-field frames if you desire a master flat.
This seems like they are referring to a dark-flat.
Does this seem correct?

Thanks for reading

Ben

Update if anyone interested. As I assume not many here bother using SSS.
The developer refers to darks and being dark-flats. Being inexperienced I was left confused.
And just a note for past users of SSS whom have moved on to other programs because SSS wouldn't accept their native RAW files, well this has been rectified.
Gave Nebulosity a trail run and to tell you the truth Mac users, save your $.
As far as I can tell, there wasn't any noticeable improvement but then again, these inexperienced eyes it isn't surprising I guess. Time will tell if I stick with SSS but for the money ease of use (apart from my hiccup) you can't go wrong.
