About 8 when you go down on the Friday. I might actually rrive the same time as you!

See you all in Galway.

Might need to order something a little stronger than coffee for you then Al??

Look forward to seeing you there.

Super work Phil!
Looking forward to seeing it in Galway.....and meeting up with you again of course!
I hope you are keeping notes on how you are developing this and would approciate if you could put it into some form of an article for the wesbite here.

Cracking job Phil, I would like to have seen that in person. It is one thing I really want to do - make a scope from scratch, mirror grinding and all. Have you got a picture of your set up?

Seanie.

I'll shoot some photos of my setup later, but here's a link to a Wiki describing the Bath Interferometer and how to build one. I started out trying to build the original Bath configuration but my beam-splitter cube is not a 50/50 reflective job and the fringe patterns were almost invisible. I had total success with the right-angle version which is actually pretty easy to align. I still have to work on mopping up stray internal reflections and improve the contrast by trying to get my laser to stop lasing! I'll knock up a webpage describing my efforts and results shortly.

If you want to build your own scope then you would do well to stroll through the links on the StellafaneATM website: stellafane.org/misc/links.html This is an excellent resource!

Phil.
