Bresser Messier NT-203s/800 EXOS-2/EQ5In the past few years the
Bresser Newton telescopes have become
the standard workhorse for Deep Sky astrophotography. We now proudly
present the second generation of this telescope, the
Bresser NT-203s/800 with Hexafoc and
fast parabolic main mirror. The Bresser
NT-203s/800 f3.9
will deliver you deeper images due to its - compared to 8" f/5 systems -
oversized primary mirror and therefore faster optical system with the
same exposure time. The
big 85 mm secondary prevents vignetting
for optimal illumination The excellent 2,5" Hexafoc focuser also does
not cause vignetting due to its large diameter and makes focussing a joy
- the smoothness and shifting-free operation sets new standards in this
price class. This groundbreaking focuser, tube rings with 44mm
universal standard dovetail and camera mounting feature and a high-end
finderscope with haircross and laser-engraved scale leave nothing to
desire even for demanding astrophotographers. The NT-203s/800 Hexafoc
has a classical tube construction with an aluminium tube. The focuser
can be upgraded with a
10:1 reduction (part No. 0625720) without problems. Also prepared for use with the
HR Coma Corrector (part No. 0510330) which eliminates coma, field-curvature and astigmatism.
Mount and
Tripod. The
BRESSER EXOS 2 is
a rugged mount with high rigidity and precision tracking for visual
observation and astrophotography. The tripod is extremely rigid to
suppress vibrations really well. This model is very well machined and
has an illuminated polar finder scope and precise graduated circles. A
powered twoaxis control (BRESSER Exos Duo) or a GoTo-Kit is available as
an optional extra. The BRESSER EXOS 2 can take the weight - depending
on length and use of up to
13 kg. This allows you to use refractors of up to 152 mm aperture and mirror telescopes of up to 203 mm aperture.
