Sky-Watcher Flextube 200P Primary Mirror Cooling Fan Mount

Rear cooling fan mount for a Sky-Watcher Flextube 200P telescope tube with no factory rear ventilation. Holds an 120x120mm fan (tested with Arctic F12 PWM PST) behind the primary mirror, mounted on silicone anti-vibration dampers to keep fan vibration off the optics.

What you'll need:
6x M3x10 countersunk (flat head) bolts
6x heat-set inserts, 3x8x5mm
1x 120x120mm fan (e.g. Arctic F12 PWM PST)
4x silicone anti-vibration fan mounts

Also, I've used the self-adhesive foam material on mountning plates and corresponding parts of the holder ring to avoid scratches and additional vibration.
