With the \u003cb\u003eMessier NT203s\/800 with Hexafoc\u003c\/b\u003e, we present the current generation of these devices. The photographic Newton with a \u003cb\u003eparabolic primary mirror\u003c\/b\u003e and a fast 203mm (8\") f\/3.9 \u003cb\u003efocal ratio\u003c\/b\u003e allows for deeper captures with the same exposure time. The large \u003cb\u003e85mm secondary mirror\u003c\/b\u003e ensures optimal illumination of the field of view, and the high-quality 2.5\" Hexafoc focuser ensures \u003cb\u003evignette-free photographs\u003c\/b\u003e. Clamps with a 44mm universal dovetail bar and a handle with camera mounting option, along with an excellent bright reticle finder, complete this high-quality device.\u003cbr\u003eThe focuser can also be upgraded with a \u003cb\u003e10:1 reduction ratio\u003c\/b\u003e (Art. No.: 0625720). For pin-sharp star images, the optional \u003cb\u003eHR coma corrector\u003c\/b\u003e (Art. No. 0510330) can be used. This is designed for both visual and photographic use, significantly optimizing image performance, especially in the peripheral areas of the visual field.\u003cbr\u003e\u003cbr\u003e\n\n\u003cb\u003eThe Mount\u003c\/b\u003e\u003cbr\u003e\u003cbr\u003e The \u003cb\u003eEXPLORE SCIENTIFIC EXOS-2 PMC-Eight GoTo mount\u003c\/b\u003e is equipped with a modern and precise GoTo control system. It consists of a robust \u003cb\u003eWi-Fi control unit\u003c\/b\u003e that provides all necessary interfaces. The \u003cb\u003eNEMA-11 stepper motors\u003c\/b\u003e are connected directly to this unit via a cable, and it also features an \u003cb\u003eST-4 compatible autoguider port\u003c\/b\u003e. Additionally, the control system supports \u003cb\u003emicro-stepping\u003c\/b\u003e to ensure precise tracking.\u003cbr\u003e\u003cbr\u003e\n\n\u003cb\u003eIntuitive operation via app and graphical star chart\u003c\/b\u003e\u003cbr\u003e The \u003cb\u003eExploreStars app\u003c\/b\u003e, specifically developed for the PMC-Eight system, impresses with its intuitive and well-designed graphical interface. The alignment stars available for control initialization and all celestial objects in the database are displayed as a star chart with additional textual information. All these objects can be easily accessed and selected.\u003cbr\u003e\u003cbr\u003e\n\n\u003cb\u003ePowerful control unit with Open GoTo for customization\u003c\/b\u003e\u003cbr\u003e The heart of the control unit is a fully autonomous multi-channel processor with \u003cb\u003e8 CPUs and a 10\/100 Ethernet Wi-Fi adapter with IP functionality\u003c\/b\u003e. This allows for remote control via a browser, ASCOM, app, or serial connection. With Open GoTo, custom firmware can also be written and uploaded to the control unit, allowing for \u003cb\u003ecustomization\u003c\/b\u003e of device functions and creation of personalized object lists, etc.\u003cbr\u003e\u003cbr\u003e\n\n\u003cb\u003ePolar finder included\u003c\/b\u003e\u003cbr\u003e The \u003cb\u003epolar finder\u003c\/b\u003e, already included and pre-installed in the set, allows for \u003cb\u003equick and precise polar alignment\u003c\/b\u003e and long exposure times without unwanted star trails.
