This adapter allows you to place the ARCO 2\" rotator directly behind the corrector for precise field de-rotation, which is essential for achieving round stars during long exposures on an alt-azimuth mount or for framing objects perfectly on an equatorial mount.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eCan I use this M48x0.75 female adapter for ARCO 2\" to connect directly to my camera?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eIt depends on your camera's connection. If your camera or filter wheel has a male M48x0.75 thread and the back focus is correct, this adapter will create the physical connection. Always verify your total back focus distance against your corrector's requirements.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eDo I need the M48x0.75 female adapter for ARCO 2\" if I am connecting to an ESATTO focuser?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThis depends on the specific ESATTO model and any reducers in your train. Many ESATTO focusers have optional adapters that terminate in M48 male threads, in which case this adapter would be the correct choice to attach the ARCO 2\" rotator.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWill this M48x0.75 adapter work with my full-frame camera and reducer on my Celestron EdgeHD telescope?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes, this is a common application. Reducers for EdgeHD telescopes often require a specific back focus and use M48 threads to connect to the camera. This adapter lets you insert the ARCO 2\" rotator into that M48-threaded imaging train, but you must ensure the final 22mm thickness of the rotator and adapter fits within your reducer's back focus budget.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eIs this adapter required to control the ARCO 2\" with a SESTO SENSO 2?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eNo, this adapter is purely a mechanical connector.
