Allows for polar alignment  as required for long exposure astrophotography and imaging.  There are no returns on this item.  \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eEquatorial alignment is required for astrophotography and imaging exposures longer than about 15 seconds. The Wedge is mounted between a telescope and the tripod to accomplish the tilt of an equatorial type mount that matches the observer's latitude and permits precise polar alignment of your telescope. The wedge allows the astrophotographer to align the telescope's axis of rotation with the Earth's axis of rotation. This alignment eliminates stars in your long exposure photograph from appearing as a long arc, trail or streak due to an effect known as field rotation. For images under approximately 15 seconds a wedge is not necessary and the telescope can be set up in altitude-azimuth (alt-az) configuration as normally used for visual observation.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Celestron","offers":[{"title":"Default Title","offer_id":45974629613827,"sku":"U2409-LP-CELWEDGE","price":75.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1979\/5379\/files\/461254800_3879925165660366_5470849236443917234_n.jpg?v=1727301946","url":"https:\/\/milehighastro.com\/products\/used-celestron-basic-wedge-for-c9-25-and-c11","provider":"Mile High Astronomy","version":"1.0","type":"link"}
