Help with flat frames.
I need some help with my flats. I started to take some flats after noticing dust bunnies on my DSI II pro camera. Th exposure was quite low as I used the white T shirt method as I havn't built a light box as yet. However when I use it with my stacked images I loose all detail in my image and wind up with just the brightest stars. I used DSS to manipulate my images but what should I be doing with the flat and what software? Is there an idiots guide for photoshop manipulation?
All help very gratefully received.
