I think I got my Osram flouro's from an IGA store in Melbourne.
It's coming together!
Your should make up a dial scale for the adjusting screw; then you can zero it @ zero image and calibrate by central wavelength - making it much easier to use in the dark on the scope. Adding a small back light red LED to the slit makes it visible and easier to position a star.
Just my 2c as usual!!
