Diogo sets this charge inside the asteroid the Xinglong is carrying. Screencaps and identification of found parts below the jump:
From left to right: Original screencap, lightly retouched version, heavily retouched version.
It appears to be made of found objects. The illuminated ‘top’ portion is a camping light by Black Diamond; either the Orbit or the Voyager, in either the 2014 or current model years. It is possible that parts were swapped together to make what we see on screen.
The tripod ‘base’ is a photographers’ monopod base; the Benro VT2 or ST1.
Various stickers have been applied to all pieces, mostly to cover-up manufacturers’ logos.
