[Utah-astronomy] Flat field

For those that image…what type of flat-field setup do you have? Did you purchase the setup or did you build your own flat-field box? What type of light source do you use? If anyone has instructions on how to build a simple flat-field light box any information (pictures would be nice) would be greatly appreciated. Make the descriptions simple. Something that someone who nearly failed shop class (really, I almost did) could understand. Failing that, give me all the technical low-down and I’ll get the wife to help me out so that it actually works when the project is completed. Dave
