The Antlia IR-pass 685 filter 1.25" is designed to boost the contrast in planetary imaging as infrared radiation is less affected by atmospheric turbulence (seeing). All planets will appear sharper with the highest possible contrast.

• Mercury: Witness the faint surface details of this elusive planet, normally hidden from view.

• Venus: See through the thick cloud cover and unveil the hidden secrets of Venus's atmosphere, especially when paired with the Antlia UV Venus filter.

• Mars: This filter truly shines for Mars, bringing out incredible geological features and even piercing through dust storms.

• Jupiter & Saturn: Witness the majestic bands and subtle details of these gas giants with unparalleled sharpness.

• Uranus and Neptune: Even these distant worlds reveal hidden beauty through the IR-Pass filter's enhanced contrast.

Specifications:

The human eye is not sensitive to infrared light so this filter is specifically designed for cameras combined with medium or large telescopes.

For larger telescopes (over 150mm), consider the Antlia IR-Pass 850 for even greater contrast.

Never look directly at the sun through any filter, including this one. Serious eye damage can occur.
