Two missing figures

Size and optical density. A solar film is bought on exactly those two things: how much area it covers and how much light it transmits. Neither appears in this listing, and the neighbouring sheet from another seller at least publishes an aperture range.

The text that travels

The same five sentences appear on this listing, on the GMBYLBY sheet and on the ihwfaityu sheet. Different sellers, identical copy. Whatever those sentences describe, they were not written about any one of the three.

What using film actually involves

Cutting it, mounting it flat in a cell that cannot fall off the tube, inspecting it for pinholes and creases before every use, and storing it so that it is not creased between sessions. Every one of those steps belongs to the buyer with a film sold as a sheet.

What this page will not say

Whether it is safe to use. It reports what is published — and here, what is not — and defers to the instructions supplied with the product.

    • Three published diameters — 100 mm outer, 75 mm inner, 70 to 92 mm tube range — rather than one vague size
    • An aluminium cell holds the film flat, which matters more than the film’s brand
    • A tube at the very edge of the 70–92 mm range sits less securely than one in the middle

    Best for: Fitting the front of a telescope whose tube outside diameter has been measured first
