Antlia has introduced a new dual band 5nm filter. Meant for one-shot color cameras such as DSLRs and astronomical OSCs, the mounted, two-inch ALP-T has narrow transmission bands for H-alpha and OIII. These bands are chosen to highlight wavelengths from nebulas while reducing interference from light pollution, airglow, and other undesirable light sources.
MSRP: $380
