RE: [APML] Blue Witch in a Red Sea
Stuart,
The schmidt has three diagonal vanes, and a big rectangular film canister
hanging in each side of the film holder for the other three spikes.
Maybe I should add some more? ;)
Chris

Chris, a beautiful shot! I would not have believed there was so much H-Alpha
in that region but I
guess most folks are so focused on pulling the blue out that the red is
lost. Wow!
The six diffraction spikes on Rigel - are they caused by the spider holding
the film roll? Why six
and not four?
