For sale : slit for spectro

For sale

A slit made on my demand by a turner but I don't need it....

- 2" tube is in aluminium
- Slit is in brass (easier to regulate the edges)

Interesting....
(For optimum results and minimal reflections the bevel edges of the slit plates should be mounted away from the telescope, facing towards the collimator)
