The PMC-Eight's 8-core processor sets it apart from conventional single-processor GOTO mounts, providing the kind of smooth, responsive tracking that astrophotographers rely on for sharp, stacked images night after night. The ExploreStars app makes polar alignment, star alignment, and object selection intuitive enough for newcomers while still offering ASCOM connectivity for experienced imagers running dedicated astronomy software. Glow-in-the-dark mount markers, smooth locking clutches, a built-in polar alignment tunnel, and a bubble level show that Explore Scientific designed this system with real-world dark-site use in mind. Whether you're imaging the Orion Nebula from your backyard, hunting Messier objects from a dark-sky site, or using the ED80 as a guide scope on a larger rig, this system adapts to how you observe. It's the kind of confident, capable setup that grows with you as your passion for astronomy deepens.\n\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eProduct Specifications\u003c\/h2\u003e\n\u003cdiv class=\"custom-product-faq\"\u003e\n\u003cdetails\u003e\n\u003csummary\u003e\u003cstrong\u003eView Product Specs\u003c\/strong\u003e\u003c\/summary\u003e\n\u003ctable border=\"1\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eItem Number\u003c\/th\u003e\n\u003ctd\u003eES-ED0806-FR0.8X-iEXOS100\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTelescope Aperture\u003c\/th\u003e\n\u003ctd\u003e80 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Length (native)\u003c\/th\u003e\n\u003ctd\u003e480 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Length (with 0.8x reducer)\u003c\/th\u003e\n\u003ctd\u003e384 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Ratio (native)\u003c\/th\u003e\n\u003ctd\u003ef\/6\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Ratio (with 0.8x reducer)\u003c\/th\u003e\n\u003ctd\u003ef\/4.8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLimiting Magnitude\u003c\/th\u003e\n\u003ctd\u003e12\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eResolution\u003c\/th\u003e\n\u003ctd\u003e1.45 arcsec\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTube Length (with dew shield)\u003c\/th\u003e\n\u003ctd\u003e18.5 in \/ 475 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTube Length (without dew shield)\u003c\/th\u003e\n\u003ctd\u003e15 in \/ 381 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTube Outer Diameter\u003c\/th\u003e\n\u003ctd\u003e91 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOptical Tube Weight\u003c\/th\u003e\n\u003ctd\u003e5.95 lb \/ 2.7 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDovetail Standard\u003c\/th\u003e\n\u003ctd\u003eVixen\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Reducer Back Spacing\u003c\/th\u003e\n\u003ctd\u003e55 mm (+\/- 2 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFocal Reducer Camera Thread\u003c\/th\u003e\n\u003ctd\u003e42 mm T-ring (standard)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMount Type\u003c\/th\u003e\n\u003ctd\u003eGerman Equatorial (GEM)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMount Connectivity\u003c\/th\u003e\n\u003ctd\u003eWiFi and Bluetooth\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMount Payload Capacity\u003c\/th\u003e\n\u003ctd\u003e19 lbs (scope + accessories + counterweights combined)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMount Weight\u003c\/th\u003e\n\u003ctd\u003e9.45 lb \/ 4.29 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTravel Tripod Weight\u003c\/th\u003e\n\u003ctd\u003e5.5 lb \/ 2.5 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTravel Tripod Collapsed Height\u003c\/th\u003e\n\u003ctd\u003e27.25 in \/ 69.21 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePMC-Eight Processor\u003c\/th\u003e\n\u003ctd\u003e8-core microcontroller\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower Source\u003c\/th\u003e\n\u003ctd\u003e8 x C batteries (not included)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eApp Compatibility\u003c\/th\u003e\n\u003ctd\u003eExploreStars (Windows, Android, Amazon, Apple)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSoftware Compatibility\u003c\/th\u003e\n\u003ctd\u003eASCOM-compliant software via free PMC-Eight ASCOM driver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/details\u003e\n\u003c\/div\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\n\u003cdiv class=\"custom-product-faq\"\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDo I need any astrophotography experience to use this bundle?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eNot necessarily. The iEXOS-100's ExploreStars app is designed to be intuitive for newcomers - it walks you through polar alignment, star alignment, and object selection step by step.
