Sorry, I believe that should be 150 mm for the aperture..

Hi,
My Baader solar film arrived today after a hiccup where the first
parcel was lost. This replacement one was already opened (probably to
check for dangerous goods?) so I`m wondering if the first parcel was
deemed as dangerous!? Here`s a couple of photos of the mask on the
cake spring form. The aperture of the hole in the cardboard sheets is
a little over 6 inches (about 150 cms or so), the spring form is 280
cm & the scope is a C9.25... My only question at this stage is how
flat must the film be held?...Ray, I`ll try your off axis suggestion
when I have more cardboard..

Mark.
