When you have a nice workable flat-field box, can you pass along the design and instructions for use? --- astrodeb@charter.net wrote: ditto for me.
The following are some notes I made on a prototype knock-off of a white light box for astrophotography that I made from a plastic kitchen trash can: http://members.csolutions.net/fisherka/astronote/atm/tclb/index.html Often it is not possible to make an astrophotography white-flat using the twilight sky. A white-light box is a convenient aid for making such flats. The Berry and Burnell HAIP book suggests a wood and foam board design for a light box. No plans were provided. HAIP at page 126. An internet search, a periodical literature search and a review of leading ATM books revealed no published plans for a white light box for astrophotography. Therefore, I tried the following plastic and glue knock-off of a variation on Berry and Burnell's design. Schematics and notes are posted here for reference by other amateur astrophotographers. Hope this is of use and interest to group members. Any comments or suggestions on the above, and links to any alterantive web-posted plans for light boxes, would be appreciated.
