Product information "BRESSER Messier NT203s/800 EXOS-2 PMC-Eight GoTo Telescope Set"
An optimal set for ambitious astrophotographers: the BRESSER Messier NT203s/800 Telescope with EXOS-2 PMC-Eight GoTo Mount. With its short f/3.9 focal ratio, this 203-mm telescope with a parabolic primary mirror allows deep sky imaging with short exposure times. The large 85 mm secondary mirror ensures optimal field illumination, while the high-quality 2.5" Hexafoc focuser enables vignetting-free photography. The modern mount impresses with its precise GoTo control and easy operation via the ExploreStars app, ensuring accurate tracking and intuitive sky navigation.
The Telescope
The BRESSER Messier Newton Telescopes have established themselves as reliable workhorses for astrophotography in recent years. With the Messier NT203s/800 with Hexafoc, we present the latest generation of these devices. The photo-Newton with a parabolic primary mirror and a fast focal ratio of 203 mm (8") f/3.9 enables deeper exposures in the same amount of time. The large 85 mm secondary mirror guarantees optimal field illumination, and the high-quality 2.5" Hexafoc focuser ensures vignetting-free photography. The tube rings with a 44-mm universal dovetail bar and handle with camera mounting option, along with an excellent bright crosshair finder, round out this high-quality device.
The focuser can also be upgraded with a 10:1 reduction gear (Art. No.: 0625720). For pinpoint star imaging, the optional HR Coma Corrector (Art. No. 0510330) can be used. This is designed for both visual and photographic use, significantly improving image quality, especially in the outer areas of the field.
The Mount
The EXPLORE SCIENTIFIC EXOS-2 PMC-Eight GoTo Mount is equipped with a modern and highly precise GoTo control system. It consists of a robust Wi-Fi controller unit that provides all necessary interfaces. The NEMA-11 stepper motors are directly connected to this unit via cable, and a ST-4 compatible autoguider port is also available. The control system also supports micro-step operation to ensure precise tracking.
Intuitive operation via app and graphical star map
The ExploreStars app, specifically developed for the PMC-Eight system, impresses with its well-designed, intuitive graphical interface. The current alignment stars for control initialization, as well as all celestial objects in the database, are displayed as a star map with additional text information. All these objects can be conveniently viewed and selected.
Powerful controller unit with Open GoTo for customization
At the heart of the controller unit is a fully autonomous 2-channel multi-processor with 8 CPUs and a Wi-Fi Ethernet 10/100 adapter with IP functionality. This allows remote operation via browser, ASCOM, app, or serial connection. With Open GoTo, custom firmware can also be written and loaded into the controller unit, allowing customization of device functions and the creation of custom object lists, etc.
Polar finder included
The included and pre-installed polar finder scope enables quick and precise polar alignment for long exposure times without unwanted star trails. The integrated LED lighting unit further enhances the user experience of the polar finder.

EXPLORE SCIENTIFIC 2" Variable Polarizing Filter

(25.32% saved)
Universally usable variable polarizing filter with a 2" filter thread.This variable polarizing filter allows for a continuous adjustment of the image brightness. This is very helpful to level strong differences in contrast of different observation objects individually. Particularly for lunar and planetary observations but also for solar observations this filter prevents an outshining of details.Solar observations ONLY together with an adequate solar filter !!! Particularly when a Herschel wedge is used and with large objective lens apertures the use of the variable polarizing filter can reduce the brightness of the observation object to a confortable level. The large adjustment range of 40% to 1% light transmission and the neutral grey filter effect create a comfortable and unadulterated image.The handling is very simple. The desired filtering level is set by turning the two sides of the housing against each other.A 2.0" filter thread on both sides (female/male) allow for the simultaneous use of additional colour filters.FEATURESvariable polarizing filterindividually adjustable image brightnessmade from high-quality optical glassblack anodized aluminium housing2.0" filter thread on both sidesSCOPE OF DELIVERYpolarizing filterprotective box
