GoPro Hero mount for 4" enclosure

[EliotBR (Eliot)]

Hi @tunadiver, thanks for sharing!

Out of interest, how’s the footage from that setup? The camera can’t be centred without taking it apart I suppose, so it wouldn’t work to use a normal dome end cap, but I’m also aware that flat lenses can have quite a bit of distortion:

Is a dome even needed? I read somewhere that even a flat window is good enough.

“Good enough” depends on your requirements. A camera with its input at the centre of a dome will have a less distorted image than one looking through a flat window, but it’s possible the reduced distortion at the edges/corners isn’t worth the extra development/expense for you. I’m hoping to make a clear guide and possibly a calculator for that at some point in future, but in the meantime you may be interested in these web pages:

• Optics of Dome Ports
• Planar Interfaces and Apparent Positions
• Dome View Ports – Best Performance Under Pressure - DeepSea Power & Light

It’s also of course possible to try out a flat end-cap and see if the results are reasonable or if a dome is required.
