Perfect for astro-photography! If your camera has a long lens, enough pixels and you enjoy the night sky, this is for you!
Based on a 58mm Canon lens cap. Should fit any camera lens by resizing it in the XY plane. Easy to use:
- place it on the lens
- point towards a bright object
- manually focus for the centre line to be right between the angled ones

20% works fine, but you be the judge of that
Only one part needs support (and I'd flip it over, for minimum amount of support material)
Focus test on nearby lights
Designed for DSLR based astro-photography, will fit on your camera's lens like a regular cap.
