Outline
|
A high quality and affordable Astrograph featuring a flat field,
comma free optical system optimised for CCD and DSLR sensors,
stars appear as pinpoints across the entire field. This exciting
new Maksutov-Newtonian is ideal for astrophotography and serious
visual observation.
The design offers apochromatic performance, very high image quality,
providing high-contrast, perfectly flat images, free from false colour
in a compact affordable package. The 190mm (7.5") Maksutov-Newtonian
optics provide high resolutions in a fast f/5.3 design keeping exposure
times shorter.
|
|
|
The primary mirror is figured from low-expansion Pyrex
glass where the front meniscus lens from quality BK7 Schott glass,
all optics are fully multi-coated for maximum light transmission.
The premium optics are housed in a robust rolled-steel tube for excellent
mechanical integrity featuring a quality Crayford focuser. Five internal
knife-edge baffles are included to eliminate internal reflections and
further enhance contrast outperforming similarly sized Schmidt-Newtonians
in contrast!
