Hi folks. What does this message that I keep getting mean? This is a dual narrowband image using an Optolong L-extreme. I've redone my flats and dark flats and I'm certain there is no light leakage. I haven't used any bias frames, and the gain, etc is the same as for my lights so I don't know what that's about. Which leaves underexposure.. well there's a decent image visible on the subs (see sub example attached)and it's not a dark subject (Horsehead nebula), so I'm at a bit of a loss as to what the issue is here and why it is critical Anyone, any ideas?
@abmwinnoch Alan, this has been explained by Mabula in this sticky post:

@wvreeven Ah sorry I should've checked that thanks. Just on my trial period so still finding my feet with the program. Certainly there's a lot of very helpful dialogue boxes throughout all the panels, which I appreciate.
@abmwinnoch No problem. If the explanation there doesn't answer your questions then please feel free to ask them here.
