If you store your telescope with the Telrad attached in the shed, garden house or under a shelter, the viewfinder will bemerk exposed to dust, moisture and dirt. A Telrad viewfinder cover like the TG-TR from Telegizmos covers the entire viewfinder, not just the viewing window. This keeps the housing and the dial covered until you detect movement.<\/p>\n\n\n\n
The cover is made for the Telrad red dot finder with base<\/a>, The famous viewfinder with three red rings that sits on a separate foot on the tube.<\/p>\n\n\n\n Always turn off the Telrad before the cover goes on it, otherwise the battery will run out without you noticing merk. If the viewfinder is wet from the dew, let it dry first, because moisture under a cover dries poorly.<\/p>\n\n\n\n If you often have a fogged window during observation, then also look at the dew cap for the Telrad viewing window<\/a>. You can find more parts for your viewfinder at accessories for seekers<\/a>.<\/p>","protected":false},"excerpt":{"rendered":" Protective cover that covers the entire Telrad viewfinder, including the window and the rotary control, for when the viewfinder is mounted on an extended telescope.<\/p>","protected":false},"featured_media":113759,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[3296],"product_cat":[3154,504,56,3093],"product_tag":[],"class_list":["post-113760","product","type-product","status-publish","has-post-thumbnail","product_brand-telegizmos","product_cat-bescherm-hoezen","product_cat-draagtassen","product_cat-telescoop-accessoires","product_cat-zoeker-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":113760,"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.
