Les images en Halpha faites avec le newton solaire ont \u00e9t\u00e9 r\u00e9alis\u00e9es avec une lentille t\u00e9l\u00e9centrique x4 de Baader dans le montage.

Cette TZ4 semble avoir \u00e9t\u00e9 con\u00e7ue pour une lunette Zeiss de 100mm de diam\u00e8tre, ce qui est assez loin du newton de 250mm.

Cette premi\u00e8re lumi\u00e8re a \u00e9t\u00e9 faite dans le rouge, afin de disposer de beaucoup de flux et limiter les temps de pose pour figer la turbulence.<\/p>\n
