This versatile OAG supports full-frame astronomy cameras and features a large 10mm x 10mm prism which gives a larger field of view that makes it easier to select a guide star.\u003c\/p\u003e\n\u003cp\u003eThe Askar M54 OAG includes threaded M42, M48, and M54 adapters to easily interface with a wide range of cameras. It also includes M42 and M48 adapters and an M54 gasket for use on the telescope side. The top of the OAG has a 1.25” adapter and M42x0.75 threads to give you two options to attach the guide camera (sold separately). It also features a scaled helical focuser with 10mm of travel to help you easily achieve focus with the guide cam.\u003c\/p\u003e\n\u003cp\u003eThe Askar OAG has a thickness of 19.5mm. It includes three threaded 18mm extender rings to match the M42, M48, and M54 camera adapters to help achieve a 55mm back focus when using cameras with a sensor recessed by 17.5mm. The extender rings can be replaced by a filter wheel of the appropriate thickness and thread size (sold separately). If a camera with a back focus other than 17.5mm is used, other extender rings will be required (sold separately).\u003c\/p\u003e\n\u003cp\u003eLike all Askar products, this M54 off-axis guider is also attractively constructed with a delicate matte black anodized finish on a precision CNC-machined aluminum body.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Askar","offers":[{"title":"Default Title","offer_id":46491679522913,"sku":"nub1787928720222","price":143.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0580\/3933\/7057\/files\/askar-m54-off-axis-guider_1.jpg?v=1787928726","url":"https:\/\/www.sunlitharbor.shop\/products\/askar-m54-off-axis-guider","provider":"My Store","version":"1.0","type":"link"}
