If you don\u2019t want to protect the lens when you\u2019re not observing, the TG-QC from Telegizmos is an objective lens cap for a 4-inch refractor that you place on the front. This keeps dust, dirt, and fingerprints away from the lens.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The cap is intended for <a href=\"https:\/\/www.telescoop.nl\/en\/telescopes\/refracting-telescopes\/\">Refracting telescopes<\/a> of 4 inches and runs across the front of the tube or the mist cap.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Before ordering, measure the outer diameter of the front of your tube or dome cap and compare it with the size of the cap. Refractors of 4 inches vary in this respect depending merk on the model. Do not put the cap back on until the lens is dry. If dew appears after observing it, let it evaporate first. If the lens still needs cleaning, check the lens cap. <a href=\"https:\/\/www.telescoop.nl\/en\/telescope-accessories\/cleaning-and-maintenance\/\">cleaning and maintenance<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you want to cover the entire telescope, there is the <a href=\"https:\/\/www.telescoop.nl\/en\/protective-case-for-4-inch-refractor-tg-r4-telescope\/\">cover for 4 inch refractors<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"<p>Telegizmos protective cap for the front of a 4 inch refractor, so dust, dirt and fingers stay away from the lens.<\/p>","protected":false},"featured_media":113751,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[3296],"product_cat":[3154,504,3150,56],"product_tag":[],"class_list":["post-113752","product","type-product","status-publish","has-post-thumbnail","product_brand-telegizmos","product_cat-bescherm-hoezen","product_cat-draagtassen","product_cat-schoonmaak-en-onderhoud","product_cat-telescoop-accessoires","first","instock","taxable","shipping-taxable","purchasable","product-type-simple"],"bundled_by":[],"bundle_stock_status":"instock","bundle_stock_quantity":null,"bundle_virtual":false,"bundle_layout":"","bundle_add_to_cart_form_location":"","bundle_editable_in_cart":false,"bundle_sold_individually_context":"","bundle_item_grouping":"","bundle_min_size":"","bundle_max_size":"","bundle_price":[],"bundled_items":[],"bundle_sell_ids":[],"acf":[],"jetpack_sharing_enabled":true,"jetpack-related-posts":[{"id":111636,"url":"https:\/\/www.telescoop.nl\/en\/zwo-seestar-s50-pro\/","url_meta":{"origin":113752,"position":0},"title":"ZWO Seestar S50 Pro","author":"Info telescoop","date":"25-08-2026","format":false,"excerpt":"The ZWO Seestar S50 Pro is the successor to the Seestar S50: 50 mm quadruplet APO (260 mm, f\/5.2), two 8.3 MP 4K sensors, a 63-degree wide-angle camera for the Milky Way up to 8K, three built-in filters, a 10,000 mAh battery (up to 9 hours), and 128 GB of storage.
