The flattener corrects curvature in the field of view. Your stars and objects remain round and sharp. Especially with large camera sensors, you can immediately see the difference. Long exposure times are less necessary thanks to the \u201caccelerated\u201d optics.<\/p>\n\n\n\n![\"Skywatchers](\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/12\/Skywatchers-0.85x-150-ED-Flattener-EvoStar-1.jpg\" "\\"\\"")

You screw the reducer directly onto the focuser of your telescope. On the camera side, you use an M48 adapter. Within minutes you are ready to shoot.<\/p>\n\n\n\n
Weighing only a few hundred grams, you don't add an extra burden. The flattener remains stable during shooting and always delivers clear and sharp images.<\/p>\n\n\n\nSpecifications<\/strong><\/h3>\n\n\n\n
