Engineered to work together seamlessly, this system provides both high-precision focusing and arc-second resolution rotation without the cable management complexity of separate components. The integrated design simplifies your setup, requiring only a single USB cable to the ESATTO for control and power, making it a streamlined solution for automated astrophotography.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eIntegrated Focus and Rotation: The ESATTO and ARCO System\u003c\/h3\u003e\n\u003cp\u003eBy including the necessary adapter, this bundle creates a rigid, low-profile focusing and rotation assembly. This integration is designed to minimize the back focus used in your optical train while providing the robust support needed for modern imaging cameras. The two devices communicate through a short link cable, meaning you only need to connect the ESATTO focuser to your EAGLE or Windows computer to command both focus and rotation, dramatically simplifying cable routing at the telescope.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eRobotic Focusing Control with the ESATTO 2\"\u003c\/h3\u003e\n\u003cp\u003eThe ESATTO 2\" is a new-generation robotic focuser with an integrated motor and advanced electronics, eliminating the need for an external controller. It offers exceptional load capacity and precise draw tube travel, ensuring no slippage even with heavy camera and filter wheel combinations. You can control the ESATTO directly via USB or wirelessly using the Virtual HandPad on a smartphone or tablet, giving you flexible and reliable remote focusing for any setup.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eArc-Second Precision with the ARCO 2\" Camera Rotator\u003c\/h3\u003e\n\u003cp\u003eThe ARCO 2\" rotator delivers incredible rotational accuracy, with a resolution of one arc-second per step. This level of precision makes it a superior tool for both perfectly framing your deep-sky targets and for acting as a field de-rotator when used with an alt-azimuth mount. Its slim profile adds minimal thickness to the imaging train, preserving precious back focus for other accessories like off-axis guiders or filter wheels.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eUnified Telescope Control with ASCOM and PLAY Software\u003c\/h3\u003e\n\u003cp\u003eFlexibility in control is central to the ESATTO and ARCO system.

For Electronically Assisted Astronomy (EAA), where you stack many short exposures, this rotation will blur the edges of the image. The ARCO's de-rotation function corrects for this, allowing you to create sharper, longer-duration stacked images of objects like the Hercules Cluster (M13).\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eI want to image the Rosette Nebula (NGC 2244) and get the perfect framing.
