Hawksmoor

Spectrometer Mk3 has moved on a bit - started to put the separate parts together and in a '4 year old kid with a new toy' sort of way I could not resist poking the fibre optic cable out the window and squinting down the camera end of the beast. Low and behold when I inserted the 0.15mm. slit and 600 line/mm. grating I could see a small displaced but definite continuous spectrum. Will it actually work? - "Tension mounts and then gets off again"

Sheds is off tomorrow as we have visitors - but maybe at the weekend ?
