Energy Rejection:

Concentrated sunli ght can create ve ry high tem peratures where i t falls,

so care must be taken to prevent melted components or fire.

For brief observing sessio ns with le ss than 80m m of apertu re when not

using a tracking mount, it can be OK to use no energy rejection at all. Be

alert for any rise in temperature of your telescope, diagonal, or Quark.

For tele scopes un der approximately 120mm of

aperture, a scre w in UV /IR cut filter can be

employed in front of the telescope diagonal. The

UV/IR cut filter reflects UV and IR light back out

the front of the telescope, reducing temperatures

inside. Do not use a UV/IR cut filter with

oil

spaced o bjective tele scopes, or any telescope

with an integrated rear field flattener or Petzval lens. The UV/IR cut filter

must be the first optical element to receive concentrated light.

the Quark. These filters pass very little light by design and so will result

in an extremely dark image if used with the Quark.
