Antlia Solar Accessories

Antlia solar accessories complete the Solar Discover CaK filter assemblies and adapt them to your telescope and camera. The 2x, 3x and 5x Barlow lenses are matched to the 5Å CaK solar filter, to reach the focal ratio the filter needs and to set image scale for high-resolution calcium K imaging.

Extension tubes in 50mm and 70mm lengths help reach focus, and the adjustable aperture diaphragm for the 5Å CaK filter stops down the telescope when a slower focal ratio is required.
