You screw the corrector 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
The flattener eliminates curvature of the image field. Your pictures will therefore be uniformly sharp. Especially with large sensors, you can see the difference immediately.<\/p>\n\n\n\n
The reducer weighs only 260 grams and adds no hassle to your setup. It remains stable during long shots, so you'll always get clear and sharp results.<\/p>\n\n\n\nSpecifications<\/strong><\/h3>\n\n\n\n
