Category: Filters
Product Description
The ZWO Methane band (CH4) filter is a special filter for photographic use.
Its FWHM is 20nm which is suitable for most IR sensitive color or mono cameras.It can reveal the detail of the target and not too dark.
It is recommended for planetary imaging such like Jupiter, Saturn and the other planets.
This filter is a 1.25″(31.7mm) filter and comes with an inner filter thread. It is protected in a plastic case.
Instead of bringing out features based on the color of the features, the Methane CH4 filter highlights aspects based on the altitude of the clouds. Bands or clouds will be brighter the higher in the atmosphere they are.
