Testar is the authorized distributor for Antlia in Australia. Antlia planetary IR-Pass and U-Venus filters are excellent for increasing contrast and revealing fine cloud details and surface structures.


The Antlia IR-pass 685 & 850 filters are designed to boost the contrast in planetary imaging as the infrared radiation is less affected by the atmospheric turbulence (seeing). All planets will appear sharper with the highest possible contrast. 

The Antlia U-Venus filter is a special UV pass filter designed to capture the clouds of Venus but also details on Jupiter. This filter uses the latest dielectric interference coating technology to achieve high transmission in the UV band at 400 Nm and exceptional cut-off of other wavelengths (OD3).
