CHROMA TECHNOLOGY H-ALPHA FILTER Size:50mm square This allows to connect two

This allows to connect two telescopes in parallel with the advantage to lower the barycenter and therefore reduce the counterweights needed

otherwise irreversible damage to eyes and equipment may occur

any 12V DC source using the supplied EFA to 5

Nebulae have a strong emission on the band of the hydrogen (H𝛼)

CHROMA TECHNOLOGY H-ALPHA FILTER Size:50mm square This allows to connect twoChroma narrowband filters are the highest performing filters on the market today. They are available with a range of bandpasses and sizes to suit any configuration where the finest image quality is of paramount importance. H alpha filters are essential for imaging nebulae and other objects which are rich in ionized hydrogen. At 656. 3nm, a narrow band emission filter is required to separate H alpha from the SII doublet (671. 6nm and 673. 1nm). All
