Just turn the wheel to the open position for focusing, and then turn it again to the closed position to keep the dust out, or to image dark frames with your ccd or dslr camera.\u003c\/p\u003e\n\u003cdiv class=\"text\" align=\"left\"\u003e\u003c\/div\u003e\n\u003cdiv align=\"left\"\u003eAstrozap's unique Focusing Cap designs fit most telescopes and performs a dual function.  The cap itself contains three holes at a calculated points around the perimeter of the cap.  When the center knob is rotated, the inside panel lines up with the holes to create the Bahtinov pattern that  admits starlight, creating the unmistakable Bahtinov diffraction spikes that enable determination of the best focus point. Turn the center knob again, and the inside panel rotates, closes the holes, and converts the focusing cap into a dust cap.\u003c\/div\u003e\n\u003cdiv align=\"left\"\u003e\u003c\/div\u003e\n\u003cdiv align=\"left\"\u003eAll Astrozap Focusing Caps are made in the USA out of solid aluminum, and powder coated to resist corrosion and retain their handsome appearance for years to come.  As one imager discovered, it is good to have an Astrozap Focusing Cap handy because one never knows when the electric focuser will quit.\u003c\/div\u003e\n\u003cdiv align=\"left\"\u003e\n\u003cbr\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cspan style=\"color: #23618b; font-family: Cabin, sans-serif; font-size: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: #ffffff; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; display: inline !important; float: none;\"\u003e\u003cspan\u003e \u003c\/span\u003e\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eIn the Box\u003c\/h3\u003e\n\u003cp data-mce-fragment=\"1\"\u003eAstrozap Focusing Cap\u003cbr\u003e\u003c\/p\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eWarranty \u0026amp; Manuals\u003cbr data-mce-fragment=\"1\"\u003e\n\u003c\/h3\u003e\n\u003cp data-mce-fragment=\"1\"\u003eLimited One Year Warranty\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv align=\"left\"\u003e\u003c\/div\u003e\n\u003cdiv align=\"left\"\u003e\u003c\/div\u003e\n\u003cdiv align=\"left\"\u003e\u003c\/div\u003e","brand":"Astrozap","offers":[{"title":"85-95mm (AZ-401)","offer_id":51942517801255,"sku":"kyb1787936833167","price":59.95,"currency_code":"USD","in_stock":true},{"title":"90-100mm (AZ-402)","offer_id":51942517834023,"sku":"phx1787936833168","price":53.65,"currency_code":"USD","in_stock":true},{"title":"101-110mm (AZ-403)","offer_id":51942517866791,"sku":"esg1787936833169","price":57.62,"currency_code":"USD","in_stock":true},{"title":"110-120mm (AZ-404)","offer_id":51942517899559,"sku":"syu1787936833170","price":58.58,"currency_code":"USD","in_stock":true},{"title":"136-146mm (AZ-405)","offer_id":51942517932327,"sku":"drh1787936833171","price":58.7,"currency_code":"USD","in_stock":true},{"title":"155-165mm (AZ-406)","offer_id":51942517965095,"sku":"fgz1787936833172","price":73.85,"currency_code":"USD","in_stock":true},{"title":"180-190mm (AZ-423)","offer_id":51942517997863,"sku":"cfm1787936833173","price":86.81,"currency_code":"USD","in_stock":true},{"title":"193-204mm (AZ-407)","offer_id":51942518030631,"sku":"yyp1787936833174","price":64.52,"currency_code":"USD","in_stock":true},{"title":"216-231mm (AZ-408)","offer_id":51942518063399,"sku":"nyk1787936833175","price":87.93,"currency_code":"USD","in_stock":true},{"title":"247-266mm (AZ-409)","offer_id":51942518096167,"sku":"vhd1787936833176","price":73.71,"currency_code":"USD","in_stock":true},{"title":"280-298mm (AZ-410)","offer_id":51942518128935,"sku":"xrn1787936833177","price":110.73,"currency_code":"USD","in_stock":true},{"title":"280-304mm (AZ-411)","offer_id":51942518161703,"sku":"rfm1787936833178","price":102.11,"currency_code":"USD","in_stock":true},{"title":"298-316mm (AZ-412)","offer_id":51942518194471,"sku":"qih1787936833179","price":98.28,"currency_code":"USD","in_stock":true},{"title":"330-342mm (AZ-413)","offer_id":51942518227239,"sku":"ogz1787936833180","price":113.52,"currency_code":"USD","in_stock":true},{"title":"395-405mm (AZ-414)","offer_id":51942518260007,"sku":"owj1787936833181","price":127.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0932\/9334\/7111\/files\/astrozap-focusing-cap_1.webp?v=1787936837","url":"https:\/\/www.morningwillow.shop\/products\/astrozap-focusing-cap","provider":"My Store","version":"1.0","type":"link"}
