1. PRODUCT DESCRIPTION

  • Blocks IR light from CCD and CMOS sensors resulting in sharper images of stars and extended objects
  • Prevents damage of expensive H-alpha solar filters by IR (and UV) light
  • Mounted in 2" cell; stackable with other 2" filters
  • Comes with protective plastic case

Most telescopes, especially refractors, are not designed to focus infrared (IR) light to the same plane as visible light. For visual observing, this doesn't matter because the human eye cannot see infrared. But silicon CCD and CMOS sensors in astronomy cameras are very sensitive to IR, so out-of-focus IR light can result in blurry images and bloated stars. By cutting out IR, the ZWO IR-CUT filter results in much sharper images of astronomical objects.

The ZWO IR-Cut filter is also useful for solar work because it blocks infrared (and ultraviolet) light from reaching and damaging expensive H-alpha solar filters.

This IR-CUT filter comes with a protective plastic case and is housed in a 2" cell with internal threads so you can stack filters together. Thread specification M48x0.75.

Note: Occasionally, the product you receive might have a slightly different cosmetic appearance or labeling than what is shown. This can often change from batch to batch according to the whims of the manufacturer. However, you will always receive a brand new, original product as described above.
