Hi All; I hope this is not too dumb of a question, but I'm totally new to imaging so here it goes. What are flats and darks and what do they do and how do you use them.

Thanks for your help.

These frames remove the dark current (chip noise) and optical curvature inherent to images. Here is a nice and simple tutorial:

I hope this helps.

Best,
