Player One Anti-Halo PRO Dual-Band 2" Ha+OIII filter

The Player One Dual-Band filter is suitable for optics with a focal ratio from f/3.6 and delivers excellent results thanks to its narrow-band design.

Excellent suppression of disturbing halos
A common problem with filters is the appearance of halos around bright stars. These disturb the appearance of an otherwise good photo considerably.
During the development of the Anti-Halo-PRO filter, special attention was therefore paid to preventing the appearance of halos.
The photo of the star Vega (above) was taken with a Canon 700D on an 8" Newtonian telescope (f/4) with an exposure time of 120 seconds and shows no halo caused by the filter. The slightly visible halo, which is offset to the upper right, was caused by the coma corrector.

High optical density outside the passbands
Unwanted wavelengths are reduced to 1/100,000, further increasing contrast and color intensity.
