Astrophotography by Dennis Friedman

After doing much reading and surfing I realized that to produce quality Astrodigital images I needed to employ digital calibration techniques. These techniques require the preparation of dark frames, flat frames, dark flat frames and bias frames. Of the four suggested methods to produce these frames I selected the Lightbox technique because it would be the easiest one for me to employ (and build) and would also allow me to generate results that would be replicable as needed.

 I came across an inexpensive and easy to assemble Lightbox which can be used to produce quality flat frames and dark flat frames.

I will be posting some flat frames, dark flat frames and bias frames when time allows
