[. . . ] This orientation gives the best focus but is not critical. We do not recommend using chrome-coated glass gobos in the MAC 500/E. They absorb more heat than enhanced aluminum gobos and are likely to break or oxidize. If used, their lifetime can be extended somewhat by inserting the gobos with the coated side towards the lamp.

Gobos less than 0. 5 mm thick may need to be secured with a drop of high temperature silicone adhesive when used in the static positions.

For best focus, the coated side of glass gobos should face out, away from the lamp. Textured glass gobos must be inserted with the smooth side facing in, towards the lamp. Uncoated side towards lamp Coated Glass Gobos Coated side towards stage When an object is held up to the uncoated side, there is a space between the object and its reflection. The edge can be seen through the uncoated side. When an object is held up to the coated side, there is no space between the object and its reflection. The edge cannot be seen through the coated side. Textured Gobos Smooth side towards lamp Textured side towards stage Gobos and Color Filters 17 Metal and image gobos The metal gobos supplied with the MAC 500/E may be used in either wheel. They are black on one side to reduce reflections; the black side must face out, away from the lamp.

The additional friction will keep the gobo from spinning. 18 MAC 500/E User Manual Changing rotating gobos WARNING! Disconnect the fixture from AC power before removing any cover. Without tools 1. Remove the top head cover as described under "Accessing parts" on page 21. Turn the gobo wheel until the easiest access to the desired gobo position is obtained. Turn the color wheel until the open position is over the gobo position. Push the gobo and retaining spring out of the back of the holder. Avoid letting the spring and gobo fall into the head. Insert the retaining spring with the bend facing out, away from the gobo. Working through the open position in the color wheel, push the gobo and spring all the way down into the gobo holder. With needlenose pliers With a little practice, this method is faster than the above method. Turn the gobo wheel until the easiest access to the desired gobo position is obtained.
