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 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\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable class=\"spec-table\" style=\"width: 100%;
