This was shot with a 6-inch Cooke telescope (photovisual triplet lens) on Tech Pan film, processed to get good contrast. The challenge was then to print it, while retaining a realistic appearance, without losing too much in highlight or shadow.

In this image can be seen the prominent craters Plato (dark floor, near the top), Copernicus (near edge at upper left) and Tycho (lower left). Tycho is notable for the system of bright rays radiating from it, which extend almost halfway round the moon.

The southern highlands are heavily cratered, while the dark lunar ‘seas’ are predominantly in the northern part of the moon. The seas are in reality waterless, and are likely to be ancient lava flows that have filled lower-lying areas of the surface.
……………………………………………………………………
The Cooke telescope has a 6-inch aperture triplet objective, with a long focal length of 108 inches (2,700mm), giving f/18. It is therefore slightly too long a focal length to record the whole disk of a full moon on a 35mm frame. The article H. Dennis Taylor, Optical Designer for T. Cooke & Sons gives a description of this very fine, but fatally flawed optical design.

Here is a comparison pair of images, one taken on Plus-X, the other on Tech Pan. Tech Pan is almost grainless at 20x enlargement, so the detail is superb. They were both taken on the same night, so differences are purely those between the 2 films. It’s just a pity (that’s an understatement) that Kodak discontinued this emulsion a few years ago. I do have a small stash, that I am saving for something really special.

    WELL its still Fantastic :)

  • (Gracefully accepts the praise) :-)

    I’ve got a 3D pair, similar to this that I’ve been meaning to scan for a while now – maybe I’ll do them next and put them up here for anyone who can free-view 3D images. For anyone that can, it’s an amazing image.

    Wow! What amazing clarity,, excellent work.

  • Thanks Basia. I had to wait until the early hours to get stable air for a really sharp image; not my time of day at all!
