Unlike other small refractor astrographs, the HAC125DX features a lightening-fast f\/2 focal ratio allowing you to capture images 5x faster than standard f\/4.9 optics. With this kind of speed that means more data in less time and no need to autoguide!\u003c\/p\u003e\n\u003cp\u003eCompared to the original HAC125, the HAC125DX features a rear focusing mechanism on the primary. This allows for a wider range of cameras to be used compared to the original model and makes focusing easier when the telescope is in use. The telescope features a 16mm image circle which is ideal for IMX533 and 585 cameras. While small, at only 15.7-inches long the HAC125DX offers a powerful imaging platform for both beginners and advanced imagers.\u003c\/p\u003e\n\u003cp\u003eThe Sky-Watcher HAC125DX is the ultimate grab-and-go astrograph. Fast optics and small size make it easier to get out and enjoy the hobby you love. Attach it to your favorite portable mount and you are ready to capture the universe in virtually no time at all! The HAC125DX is not just another astrograph, it’s a Minigraph that is ready for all your astronomy adventures.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eDownload the \u003ca rel=\"noopener\" title=\"Sky-Watcher HAC125DX Minigraph Product Sheet - PDF\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0851\/2766\/files\/Sky-Watcher_HAC125_Product_Sheet.pdf?v=1743450471\" target=\"_blank\"\u003eHAC125DX Product Sheet\u003c\/a\u003e for the latest information from Sky-Watcher!\u003c\/em\u003e\u003c\/p\u003e\n\u003ctable class=\"spec-table\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eOptical Specifications\u003c\/th\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptical Design\u003c\/td\u003e\n\u003ctd\u003eHonders Advanced Catadioptric\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMirror Coating\u003c\/td\u003e\n\u003ctd\u003eRadiant Aluminum Quartz (RAQ)™ Coatings\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReflectivity\u003c\/td\u003e\n\u003ctd\u003e0.94\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMirror Type (Monolithic\/Conical\/Fused conical)\u003c\/td\u003e\n\u003ctd\u003eMangin\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCorrector Coating\u003c\/td\u003e\n\u003ctd\u003eHTMC™\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGlass Type\u003c\/td\u003e\n\u003ctd\u003eBorosilicate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary Aperture (mm)\u003c\/td\u003e\n\u003ctd\u003e125\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eF\/Ratio\u003c\/td\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFocal Length (mm)\u003c\/td\u003e\n\u003ctd\u003e250mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eImage Circle\u003c\/td\u003e\n\u003ctd\u003e16mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSecondary Obstruction by Diameter\u003c\/td\u003e\n\u003ctd\u003e53mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSecondary Obstruction by Area\u003c\/td\u003e\n\u003ctd\u003e0.425\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary cell supports (how many support points)\u003c\/td\u003e\n\u003ctd\u003eRear Support\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptical Quality\u003c\/td\u003e\n\u003ctd\u003eDiffraction limited (1\/4 wave)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCollimatable Cell\u003c\/td\u003e\n\u003ctd\u003ePrimary\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eMechanical Specifications\u003c\/th\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eFocuser Type\u003c\/td\u003e\n\u003ctd\u003ePrimary focus\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFocuser Size\u003c\/td\u003e\n\u003ctd\u003ePrimary Mirror Helical\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFocuser: Dual or Single Speed\u003c\/td\u003e\n\u003ctd\u003eSingle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompression Ring\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptical Tube length\u003c\/td\u003e\n\u003ctd\u003e15.7 inches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptical Tube diameter\u003c\/td\u003e\n\u003ctd\u003e6.3 inches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOptical Tube weight\u003c\/td\u003e\n\u003ctd\u003e8.4 pounds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eAccessories\u003c\/th\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eIncluded finder\u003c\/td\u003e\n\u003ctd\u003eNone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Hardware\u003c\/td\u003e\n\u003ctd\u003eClamshell rings with V-style dovetail\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAdditional Accessories\u003c\/td\u003e\n\u003ctd\u003e1.25\" \u0026amp;
