Part of the Optolong SHO-3nm filter kit, which includes SII 3nm, H-Alpha 3nm, and OIII 3nm narrowband filters, generally working with astronomical monochrome cooling CCD and modified DSLR imaging in each single-channel. Corresponding with RGB channel (HA, OIII, SII), photographers can process Hubble images by astronomical post processing software.
The Crayford GSO eyepiece lift with linear bearings is a modern, technically advanced spectacle lift, which is a breakthrough among this type of device. The structure was designed based on two precision bearings moving on a steel rail, which improves the precision of adjustment and ensures increased load capacity (4.1 kg) compared to standard lifts. This allows stable attachment of even heavy astrophotography accessories.
