You have a high-resolution CCD camera and a sharp Canon lens? With this adapter, you can connect both to each other for wide field imaging via the M48 system.
The adapter set consists of:
-- Canon EOS "female" Adapter for the lens
-- short male M48 Adapter (length of both 14.5mm)
-- three extension tubes with 6.8, 13.8 and 28.1 mm length
The correct distances:
Canon lenses have a back focus of 44mm. The shortest adapter length is 14.5 mm. So you have 29.5mm of backfocus you can use e.g. for a filter wheel or short off-axis-guider. If such accessories are not needed, the distance can be bridged by the bypacked spacers or M48 extensions (see "accessories" section).
