Lens Types, Resolution, and Sensor Coverage

[@jackhammond1253]

Hi Nick. Thank you for this good technical video. But can you recommend me a manual teleconverter to extend my bridge camera, {camera is Chinese product with 8M, and it is 4k for photos, and HD for video, with 30mm manual lens, f.1.6 and optical magnification 20x times and digital zoom 4x times}.I need this extension for the night-sky, because the zoom creates aberration for objects being far away. Thanks again, and I am awaiting for your response..
