Check the CCD window very carefully to make sure there isn't any dust. If need be, gently rub with a cotton ball to eliminate it. If there are fingerprints, blow onto the window and rub immediately with a cotton ball. The secret to good cleaning is to change cotton balls very often, otherwise greasy substances will leave traces where you just removed them!

Mount the front side onto the central body and attach it with FHc M3x30 screws.

The distance between the front of the CCD window and the front of the camera (42-mm diameter threading support plane) is about 18 mm. When the 3-mm thick optical window of the camera is in place, the focus position decreases due to the refraction in t hence the final focus position 18 - 1 = 17 mm. This has been provided to allow the use of high ratio aperture focal reducers with Audine.

Front side during assembly. Avoid running the heating resistance wires in front of the CCD. Attaching the fan: attach it in the middle of the dissipator using 4.2-mm diameter and 25-mm long steel screws. They should be screwed in between the dissipator fins (a Phillips screwdriver is required).

Fan during assembly. The fan's power supply wire should not hang out to avoid getting caught on something accidentally during camera handling.

The Audine camera dissipator is designed to hold a 50x50 mm fan used for cooling microprocessors, but a more conventional, 60x60 mm fan can also be used. The latter is more efficient and makes it possible to lower the temperature 2 or 3 more degrees Celsius. However, it has the disadvantage of being bulkier, so be careful if the camera has to fit into a telescope fork. To attach it, use piano strings (presence of holes at the top of the fins) or double-sided adhesive tape. The second solution is easy and offe vibrations related to a poorly-balanced fan. The fan should be a direct current (DC) 12V model.

Model of an Audine camera with a large-size fan. Note the presence of two threaded holes on the sides of the front part for mounting the camera on a tripod, for example (warning: one of the holes is 6 mm-metric thread, the other 6.35-mm photographic thread known as "Kodak thread".

To conclude these instructions for mechanical assembly of the Audine camera, three options should be pointed out, aimed at increasing the performance of your system or better controling its operation:

Thermal insulation of the cold drain makes it possible to gain a few precious degrees on the CCD temperature.
Efficient protection against CCD frost.
Addition of a thermal probe to determine the CCD temperature at any time.

Your Audine camera is finally finished. Congratulations! All you have to do is add a holder for your eyepiece diameter and you're ready for adventure...

Holder for 31.75 eyepiece diameter has been screwed onto the front. It gives the Audine camera scale.
