Instead of a secondary mirror, the MAK\u003cspan\u003e \u003c\/span\u003efeatures a “secondary spot” of reflective coating applied directly to the inside of the corrector plate. Because of this, the spotting scope\u003cspan\u003e \u003c\/span\u003edoes not require occasional collimation. Also, the secondary spot is significantly smaller, giving the MAK\u003cspan\u003e \u003c\/span\u003eits signature high-contrast views.\u003c\/p\u003e \u003cp\u003eOne important thing to note about Maksutov-Cassegrain spotting scope is that the larger, heavier Maksutov corrector plate takes longer to cool down and adjust to ambient air temperature.\u003c\/p\u003e","brand":"Celestron","offers":[{"title":"Default Title","offer_id":44926772084815,"sku":"52268","price":279.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0675\/2406\/7407\/files\/52268_C90_Mak_1.jpg?v=1776998818","url":"https:\/\/hobbytechsupply.com\/products\/c90-mak-spotting-scope","provider":"Hobby Tech Supply","version":"1.0","type":"link"}
