New Spectra-L200 Littrow Spectroscope

[Merlin66]

Over the last few months I've been designing and building a 200mm f7 Littrow Spectroscope.

It's currently fitted with a 600 l/mm blazed grating and undergoing calibration testing.

Finally, I think the end is is sight.....

I'd like to thank Peter (Psychobilly) :icon_salut:for all the help and assistance with suppliers. Appreciated.

Peter,

Thanks:o:o

BTW it's not red.... it's "Ozzie Shiraz" ( My wife said it was Burgundy - but that's a french wine:rolleyes: )

To answer the questions:

It's fitted with a modified Vixen flip mirror (modified to a 80/20 beamsplitter) and has the QHY5 guide camera.
