  If you're planning to do a lot of filming and don't want to spend a lot
  of money, I suggest investing in (retrofitting?) a long persistence
  phosphor monitor for your Sun.  It is possible to get a good picture
  by aiming a NTSC camera at it.

  Personally, I have used this technique at 30Hz interlaced (shooting
  off a RGB monitor), and had very good results.  In fact, as long as
  you keep glare off the screen, the results are very comparable to
  encoding the signal from RGB to NTSC.
