Antlia Solar Discover Dualband mini is a modern astronomical filter dedicated to use in astrophotography of the solar surface.

The Antlia Solar Discover Dualband mini filter provides significantly better image quality and detail compared to traditional solar films. The optical design of the filter has been developed to provide the best protection for photosensitive matrices while optimizing transmission windows in the CaK, CaH and Hα bands.

Note! The Antlia Solar Discover Dualband mini filter is designed to work exclusively with ultra-sensitive astronomical cameras and is not recommended for visual observations. Using a filter with angle attachments requires the use of an additional ERF filter.
