Selling my L200 Spectroscope, beam splitter and test lamp. This was built from the original kit supplied by merlin66.


It has the original 600 lines/mm grating.


The beam splitter is a Vixen Flip Mirror modified to remove the mirror and replace it with a beam splitter plate. Currently it is fitted with a 75R/25T beam splitter plate i.e. 75% reflected to the L200 and 25% transmitted to the guide camera. There are also 6 off spare 75R/25T beam splitters, and 7 off spare 50/50 beam splitters as well as the original mirror for the Vixen.


There was an upgrade test lamp kit which is also included built into the spectroscope.


Also included is a fair collection of T mount fittings for camera mounting/focussing.


This is the next step up in spectroscopy from the staranalyser.


I was thinking that I'd keep this as a memento I was so happy with the build, but I guess I'd prefer to see it being used for what it's designed to do.



$600 plus postage or pickup in Oberon NSW.

I found some photos of it installed on my scope.


I ended up with it "sideways" to fit the SBIG ST8I on it.
